A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that utilizes citrate as a sole carbon source. It is pathogenic for humans, causing enteric fevers, gastroenteritis, and bacteremia. Food poisoning is the most common clinical manifestation. Organisms within this genus are separated on the basis of antigenic characteristics, sugar fermentation patterns, and bacteriophage susceptibility.
Salmonella Food Poisoning
Salmonella paratyphi A
Salmonella paratyphi B
Distinct units in some bacterial, bacteriophage or plasmid GENOMES that are types of MOBILE GENETIC ELEMENTS. Encoded in them are a variety of fitness conferring genes, such as VIRULENCE FACTORS (in "pathogenicity islands or islets"), ANTIBIOTIC RESISTANCE genes, or genes required for SYMBIOSIS (in "symbiosis islands or islets"). They range in size from 10 - 500 kilobases, and their GC CONTENT and CODON usage differ from the rest of the genome. They typically contain an INTEGRASE gene, although in some cases this gene has been deleted resulting in "anchored genomic islands".
Gene Expression Regulation, Bacterial
A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.
Salmonella paratyphi C
Electrophoresis, Gel, Pulsed-Field
Gel electrophoresis in which the direction of the electric field is changed periodically. This technique is similar to other electrophoretic methods normally used to separate double-stranded DNA molecules ranging in size up to tens of thousands of base-pairs. However, by alternating the electric field direction one is able to separate DNA molecules up to several million base-pairs in length.
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Drug Resistance, Multiple, Bacterial
A whiplike motility appendage present on the surface cells. Prokaryote flagella are composed of a protein called FLAGELLIN. Bacteria can have a single flagellum, a tuft at one pole, or multiple flagella covering the entire surface. In eukaryotes, flagella are threadlike protoplasmic extensions used to propel flagellates and sperm. Flagella have the same basic structure as CILIA but are longer in proportion to the cell bearing them and present in much smaller numbers. (From King & Stansfield, A Dictionary of Genetics, 4th ed)
The lipopolysaccharide-protein somatic antigens, usually from gram-negative bacteria, important in the serological classification of enteric bacilli. The O-specific chains determine the specificity of the O antigens of a given serotype. O antigens are the immunodominant part of the lipopolysaccharide molecule in the intact bacterial cell. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)
Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.
Microbial Sensitivity Tests
A family of gram-negative, facultatively anaerobic, rod-shaped bacteria that do not form endospores. Its organisms are distributed worldwide with some being saprophytes and others being plant and animal parasites. Many species are of considerable economic importance due to their pathogenic effects on agriculture and livestock.
Colony Count, Microbial
Enumeration by direct count of viable, isolated bacterial, archaeal, or fungal CELLS or SPORES capable of growth on solid CULTURE MEDIA. The method is used routinely by environmental microbiologists for quantifying organisms in AIR; FOOD; and WATER; by clinicians for measuring patients' microbial load; and in antimicrobial drug testing.
Drug Resistance, Bacterial
A parasexual process in BACTERIA; ALGAE; FUNGI; and ciliate EUKARYOTA for achieving exchange of chromosome material during fusion of two cells. In bacteria, this is a uni-directional transfer of genetic material; in protozoa it is a bi-directional exchange. In algae and fungi, it is a form of sexual reproduction, with the union of male and female gametes.
Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed)
Drug Resistance, Microbial
The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).
Those components of an organism that determine its capacity to cause disease but are not required for its viability per se. Two classes have been characterized: TOXINS, BIOLOGICAL and surface adhesion molecules that effect the ability of the microorganism to invade and colonize a host. (From Davis et al., Microbiology, 4th ed. p486)
Polymerase Chain Reaction
In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
DNA Transposable Elements
Discrete segments of DNA which can excise and reintegrate to another site in the genome. Most are inactive, i.e., have not been found to exist outside the integrated state. DNA transposable elements include bacterial IS (insertion sequence) elements, Tn elements, the maize controlling elements Ac and Ds, Drosophila P, gypsy, and pogo elements, the human Tigger elements and the Tc and mariner elements which are found throughout the animal kingdom.
The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

Sequence Analysis, DNA
Thin, hairlike appendages, 1 to 20 microns in length and often occurring in large numbers, present on the cells of gram-negative bacteria, particularly Enterobacteriaceae and Neisseria. Unlike flagella, they do not possess motility, but being protein (pilin) in nature, they possess antigenic and hemagglutinating properties. They are of medical importance because some fimbriae mediate the attachment of bacteria to cells via adhesins (ADHESINS, BACTERIAL). Bacterial fimbriae refer to common pili, to be distinguished from the preferred use of "pili", which is confined to sex pili (PILI, SEX).
Mutagenesis where the mutation is caused by the introduction of foreign DNA sequences into a gene or extragenic sequence. This may occur spontaneously in vivo or be experimentally induced in vivo or in vitro. Proviral DNA insertions into or adjacent to a cellular proto-oncogene can interrupt GENETIC TRANSLATION of the coding sequences or interfere with recognition of regulatory elements and cause unregulated expression of the proto-oncogene resulting in tumor formation.
A complex sulfated polymer of galactose units, extracted from Gelidium cartilagineum, Gracilaria confervoides, and related red algae. It is used as a gel in the preparation of solid culture media for microorganisms, as a bulk laxative, in making emulsions, and as a supporting medium for immunodiffusion and immunoelectrophoresis.
A technique for identifying individuals of a species that is based on the uniqueness of their DNA sequence. Uniqueness is determined by identifying which combination of allelic variations occur in the individual at a statistically relevant number of different loci. In forensic studies, RESTRICTION FRAGMENT LENGTH POLYMORPHISM of multiple, highly polymorphic VNTR LOCI or MICROSATELLITE REPEAT loci are analyzed. The number of loci used for the profile depends on the ALLELE FREQUENCY in the population.
A dilated cavity extended caudally from the hindgut. In adult birds, reptiles, amphibians, and many fishes but few mammals, cloaca is a common chamber into which the digestive, urinary and reproductive tracts discharge their contents. In most mammals, cloaca gives rise to LARGE INTESTINE; URINARY BLADDER; and GENITALIA.
Lethal Dose 50
The phenomenon by which a temperate phage incorporates itself into the DNA of a bacterial host, establishing a kind of symbiotic relation between PROPHAGE and bacterium which results in the perpetuation of the prophage in all the descendants of the bacterium. Upon induction (VIRUS ACTIVATION) by various agents, such as ultraviolet radiation, the phage is released, which then becomes virulent and lyses the bacterium.
Bacterial Secretion Systems
In GRAM NEGATIVE BACTERIA, multiprotein complexes that function to translocate pathogen protein effector molecules across the bacterial cell envelope, often directly into the host. These effectors are involved in producing surface structures for adhesion, bacterial motility, manipulation of host functions, modulation of host defense responses, and other functions involved in facilitating survival of the pathogen. Several of the systems have homologous components functioning similarly in GRAM POSITIVE BACTERIA.
Animals which have become adapted through breeding in captivity to a life intimately associated with humans. They include animals domesticated by humans to live and breed in a tame condition on farms or ranches for economic reasons, including LIVESTOCK (specifically CATTLE; SHEEP; HORSES; etc.), POULTRY; and those raised or kept for pleasure and companionship, e.g., PETS; or specifically DOGS; CATS; etc.
Bacterial Outer Membrane Proteins
An antibiotic first isolated from cultures of Streptomyces venequelae in 1947 but now produced synthetically. It has a relatively simple structure and was the first broad-spectrum antibiotic to be discovered. It acts by interfering with bacterial protein synthesis and is mainly bacteriostatic. (From Martindale, The Extra Pharmacopoeia, 29th ed, p106)
A bacterial DNA topoisomerase II that catalyzes ATP-dependent breakage of both strands of DNA, passage of the unbroken strands through the breaks, and rejoining of the broken strands. Gyrase binds to DNA as a heterotetramer consisting of two A and two B subunits. In the presence of ATP, gyrase is able to convert the relaxed circular DNA duplex into a superhelix. In the absence of ATP, supercoiled DNA is relaxed by DNA gyrase.
Deliberate stimulation of the host's immune response. ACTIVE IMMUNIZATION involves administration of ANTIGENS or IMMUNOLOGIC ADJUVANTS. PASSIVE IMMUNIZATION involves administration of IMMUNE SERA or LYMPHOCYTES or their extracts (e.g., transfer factor, immune RNA) or transplantation of immunocompetent cell producing tissue (thymus or bone marrow).
Acute illnesses, usually affecting the GASTROINTESTINAL TRACT, brought on by consuming contaminated food or beverages. Most of these diseases are infectious, caused by a variety of bacteria, viruses, or parasites that can be foodborne. Sometimes the diseases are caused by harmful toxins from the microbes or other chemicals present in the food. Especially in the latter case, the condition is often called food poisoning.
Evaluation Studies as Topic
One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.
The presence of viable bacteria circulating in the blood. Fever, chills, tachycardia, and tachypnea are common acute manifestations of bacteremia. The majority of cases are seen in already hospitalized patients, most of whom have underlying diseases or procedures which render their bloodstreams susceptible to invasion.
Porins are protein molecules that were originally found in the outer membrane of GRAM-NEGATIVE BACTERIA and that form multi-meric channels for the passive DIFFUSION of WATER; IONS; or other small molecules. Porins are present in bacterial CELL WALLS, as well as in plant, fungal, mammalian and other vertebrate CELL MEMBRANES and MITOCHONDRIAL MEMBRANES.
Sensitivity and Specificity
Components of the Salmonella flagellar export apparatus and classification of export substrates. (1/3075)Until now, identification of components of the flagellar protein export apparatus has been indirect. We have now identified these components directly by establishing whether mutants defective in putative export components could translocate export substrates across the cytoplasmic membrane into the periplasmic space. Hook-type proteins could be exported to the periplasm of rod mutants, indicating that rod protein export does not have to precede hook-type protein export and therefore that both types of proteins belong to a single export class, the rod/hook-type class, which is distinct from the filament-type class. Hook-capping protein (FlgD) and hook protein (FlgE) required FlhA, FlhB, FliH, FliI, FliO, FliP, FliQ, and FliR for their export to the periplasm. In the case of flagellin as an export substrate, because of the phenomenon of hook-to-filament switching of export specificity, it was necessary to use temperature-sensitive mutants and establish whether flagellin could be exported to the cell exterior following a shift from the permissive to the restrictive temperature. Again, FlhA, FlhB, FliH, FliI, and FliO were required for its export. No suitable temperature-sensitive fliQ or fliR mutants were available. FliP appeared not to be required for flagellin export, but we suspect that the temperature-sensitive FliP protein continued to function at the restrictive temperature if incorporated at the permissive temperature. Thus, we conclude that these eight proteins are general components of the flagellar export pathway. FliJ was necessary for export of hook-type proteins (FlgD and FlgE); we were unable to test whether FliJ is needed for export of filament-type proteins. We suspect that FliJ may be a cytoplasmic chaperone for the hook-type proteins and possibly also for FliE and the rod proteins. FlgJ was not required for the export of the hook-type proteins; again, because of lack of a suitable temperature-sensitive mutant, we were unable to test whether it was required for export of filament-type proteins. Finally, it was established that there is an interaction between the processes of outer ring assembly and of penetration of the outer membrane by the rod and nascent hook, the latter process being of course necessary for passage of export substrates into the external medium. During the brief transition stage from completion of rod assembly and initiation of hook assembly, the L ring and perhaps the capping protein FlgD can be regarded as bona fide export components, with the L ring being in a formal sense the equivalent of the outer membrane secretin structure of type III virulence factor export systems.

Sensitivity, specificity, and predictive values of three Salmonella rapid detection kits using fresh and frozen poultry environmental samples versus those of standard plating. (2/3075)To reduce human exposure to Salmonella spp. in poultry products, broiler chicken flocks have been tested by culture methods. Since the standard techniques may take 3 to 5 days, rapid detection methods have been developed. In this study we tested the performance of three rapid tests originally developed for food samples by using environmental samples obtained from poultry houses. These rapid tests were Reveal, an enzyme-linked immunosorbent assay from Neogen Corp.; BIND, a bacterial ice nucleation detection method from Idetek Corp.; and a filter monitor method from Future Medical Technologies, Inc. For the standard culture, brilliant green with novabiocin and xylose-lysine-tergitol-4 agar were used for presumptive identification, and identities were confirmed by using poly-O antisera. Environmental samples were collected from farms belonging to an integrated poultry company prior to chick placement and 1 week before slaughter. Sensitivities, specificities, and predictive values with 95% confidence intervals were calculated. Statistical differences were determined by using McNemar's chi square test. The sensitivities of the different tests were not stable, varying widely between sample times, and were affected by freezing of the samples. All of the rapid tests had low sensitivities, which led to many false-negative results. All tests were able to detect Salmonella spp. at a concentration of 10 CFU/ml in at least one of four trials. The BIND and Reveal tests were simple to use with multiple samples and reduced laboratory time by up to 1 day. Based on our results, we do not recommend that any of these rapid tests, in their present state of development, be utilized with environmental samples collected with drag swabs. (+info)
The Salmonella invasin SipB induces macrophage apoptosis by binding to caspase-1. (3/3075)Recently, Salmonella spp. were shown to induce apoptosis in infected macrophages. The mechanism responsible for this process is unknown. In this report, we establish that the Inv-Spa type III secretion apparatus target invasin SipB is necessary and sufficient for the induction of apoptosis. Purified SipB microinjected into macrophages led to cell death. Binding studies show that SipB associates with the proapoptotic protease caspase-1. This interaction results in the activation of caspase-1, as seen in its proteolytic maturation and the processing of its substrate interleukin-1beta. Caspase-1 activity is essential for the cytotoxicity. Functional inhibition of caspase-1 activity by acetyl-Tyr-Val-Ala-Asp-chloromethyl ketone blocks macrophage cytotoxicity, and macrophages lacking caspase-1 are not susceptible to Salmonella-induced apoptosis. Taken together, the data demonstrate that SipB functions as an analog of the Shigella invasin IpaB. (+info)
Evaluation of accuracy and repeatability of identification of food-borne pathogens by automated bacterial identification systems. (4/3075)The performances of five automated microbial identification systems, relative to that of a reference identification system, for their ability to accurately and repeatedly identify six common food-borne pathogens were assessed. The systems assessed were the MicroLog system (Biolog Inc., Hayward, Calif.), the Microbial Identification System (MIS; MIDI Inc., Newark, Del.), the VITEK system (bioMerieux Vitek, Hazelwood, Mo.), the MicroScan WalkAway 40 system (Dade-MicroScan International, West Sacramento, Calif.), and the Replianalyzer system (Oxoid Inc., Nepean, Ontario, Canada). The sensitivities and specificities of these systems for the identification of food-borne isolates of Bacillus cereus, Campylobacter jejuni, Listeria monocytogenes, Staphylococcus aureus, Salmonella spp., and verotoxigenic Escherichia coli were determined with 40 reference positive isolates and 40 reference negative isolates for each pathogen. The sensitivities of these systems for the identification of these pathogens ranged from 42.5 to 100%, and the specificities of these systems for the identification of these pathogens ranged from 32.5 to 100%. Some of the systems had difficulty correctly identifying the reference isolates when the results were compared to those from the reference identification tests. The sensitivity of MIS for the identification of S. aureus, B. cereus, E. coli, and C. jejuni, for example, ranged from 47.5 to 72. 5%. The sensitivity of the Microlog system for the identification of E. coli was 72.5%, and the sensitivity of the VITEK system for the identification of B. cereus was 42.5%. The specificities of four of the five systems for the identification of all of the species tested with the available databases were greater than or equal to 97.5%; the exception was MIS for the identification of C. jejuni, which displayed a specificity of 32.5% when it was tested with reference negative isolates including Campylobacter coli and other Campylobacter species. All systems had >80% sensitivities for the identification of Salmonella species and Listeria species at the genus level. The repeatability of these systems for the identification of test isolates ranged from 30 to 100%. Not all systems included all six pathogens in their databases; thus, some species could not be tested with all systems. The choice of automated microbial identification system for the identification of a food-borne pathogen would depend on the availability of identification libraries within the systems and the performance of the systems for the identification of the pathogen.

How intracellular bacteria survive: surface modifications that promote resistance to host innate immune responses. (5/3075)Bacterial pathogens regulate the expression of virulence factors in response to environmental signals. In the case of salmonellae, many virulence factors are regulated via PhoP/PhoQ, a two-component signal transduction system that is repressed by magnesium and calcium in vitro. PhoP/PhoQ-activated genes promote intracellular survival within macrophages, whereas PhoP-repressed genes promote entrance into epithelial cells and macrophages by macropinocytosis and stimulate epithelial cell cytokine production. PhoP-activated genes include those that alter the cell envelope through structural alterations of lipopolysaccharide and lipid A, the bioactive component of lipopolysaccharide. PhoP-activated changes in the bacterial envelope likely promote intracellular survival by increasing resistance to host cationic antimicrobial peptides and decreasing host cell cytokine production.

Lipopolysaccharides (LPS) of oral black-pigmented bacteria induce tumor necrosis factor production by LPS-refractory C3H/HeJ macrophages in a way different from that of Salmonella LPS. (6/3075)Some lipopolysaccharide (LPS) preparations from S- or R-form members of the family Enterobacteriaceae and oral black-pigmented bacteria (Porphyromonas gingivalis and Prevotella intermedia) are known to activate LPS-refractory C3H/HeJ macrophages. When contaminating proteins are removed from R-form LPS of Enterobacteriaceae by repurification, however, this ability is lost. In the present study, we investigated the capacity of LPS from P. gingivalis, P. intermedia, Salmonella minnesota, and Salmonella abortusequi to induce production of tumor necrosis factor (TNF) in gamma interferon-primed C3H/HeJ macrophages before and after repurification. P. abortusequi S-LPS was fractionated by centrifugal partition chromatography into two LPS forms: SL-LPS, having homologous long O-polysaccharide chains, and SS-LPS having short oligosaccharide chains. Prior to repurification, all LPS forms except SL-LPS induced TNF production in both C3H/HeJ and C3H/HeN macrophages. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed that repurification removed contaminating protein from the preparations, and repurified SS-LPS and S. minnesota Ra-LPS no longer stimulated TNF production in C3H/HeJ macrophages, although C3H/HeN macrophages remained responsive. In contrast, repurified oral bacterial LPS retained the capacity to induce TNF production in C3H/HeJ macrophages. Oral bacterial LPS preparations also were not antagonized by excess inactive, repurified SL-LPS; Ra-LPS; Rhodobacter sphaeroides lipid A, a competitive LPS antagonist, or paclitaxel, an LPS agonist, and they were comparatively resistant to polymyxin B treatment. Nevertheless, oral bacterial LPS was less toxic to D-galactosamine-treated C3H/HeN mice than was LPS from Salmonella. These findings indicate that the active molecule(s) and mode of action of LPS from P. gingivalis and P. intermedia are quite different from those of LPS from Salmonella. (+info)
The cyclic structure of microcin J25, a 21-residue peptide antibiotic from Escherichia coli. (7/3075)Microcin J25 (MccJ25) is the single representative of the immunity group J of the microcin group of peptide antibiotics produced by Enterobacteriaceae. It induces bacterial filamentation in susceptible cells in a non-SOS-dependent pathway [R. A. Salomon and R. Farias (1992) J. Bacteriol. 174, 7428-7435]. MccJ25 was purified to homogeneity from the growth medium of a microcin-overproducing Escherichia coli strain by reverse-phase HPLC. Based on amino acid composition and absolute configuration determination, liquid secondary ion and electrospray mass spectrometry, extensive two-dimensional NMR, enzymatic and chemical degradations studies, the structure of MccJ25 was elucidated as a 21-residue peptide, cyclo(-Val1-Gly-Ile-Gly-Thr- Pro-Ile-Ser-Phe-Tyr-Gly-Gly-Gly-Ala-Gly-His-Val-Pro-Glu-Tyr-Phe21- ). Although MccJ25 showed high resistance to most of endoproteases, linearization by thermolysin occurred from cleavage at the Phe21-Val1 bond and led to a single peptide, MccJ25-L. While MccJ25 exhibited remarkable antibiotic activity towards Salmonella newport and several E. coli strains (minimal inhibitory concentrations ranging between 0.01 and 0.2 microgram.mL-1), the thermolysin-linearized microcin showed a dramatic decrease of the activity, indicating that the cyclic structure is essential for the MccJ25 biological properties. As MccJ25 is ribosomally synthesized as a larger peptide precursor endowed with an N-terminal extremity, the present study shows that removal of this extension and head-tail cyclization of the resulting propeptide are the only post-translational modifications involved in the maturation of MccJ25, that appears as the first cyclic microcin.

Presence of Campylobacter and Salmonella in sand from bathing beaches. (8/3075)The purpose of this study was to determine the presence of thermophilic Campylobacter spp. and Salmonella spp. in sand from non-EEC standard and EEC standard designated beaches in different locations in the UK and to assess if potentially pathogenic strains were present. Campylobacter spp. were detected in 82/182 (45%) of sand samples and Salmonella spp. in 10/182 (6%). Campylobacter spp. were isolated from 46/92 (50%) of samples from non-EEC standard beaches and 36/90 (40%) from EEC standard beaches. The prevalence of Campylobacter spp. was greater in wet sand from both types of beaches but, surprisingly, more than 30% of samples from dry sand also contained these organisms. The major pathogenic species C. jejuni and C. coli were more prevalent in sand from non-EEC standard beaches. In contrast, C. lari and urease positive thermophilic campylobacters, which are associated with seagulls and other migratory birds, were more prevalent in sand from EEC standard beaches. Campylobacter isolates were further characterized by biotyping and serotyping, which confirmed that strains known to be of types associated with human infections were frequently found in sand on bathing beaches.

Epidemiology of Salmonella sp. in California cull dairy cattle: prevalence of fecal shedding and diagnostic accuracy of pooled...
Background The primary objective of this cross-sectional study was to estimate the crude, seasonal and cull-reason stratified prevalence of Salmonella fecal shedding in cull dairy cattle on seven California dairies. A secondary objective was to estimate and compare the relative sensitivity (Se) and specificity (Sp) for pools of 5 and 10 enriched broth cultures of fecal samples for Salmonella sp. detection. Methods Seven dairy farms located in the San Joaquin Valley of California were identified and enrolled in the study as a convenience sample. Cull cows were identified for fecal sampling once during each season between 2014 and 2015, specifically during spring, summer, fall, and winter, and 10 cows were randomly selected for fecal sampling at the day of their sale. In addition, study personnel completed a survey based on responses of the herd manager to questions related to the previous four months herd management. Fecal samples were frozen until testing for Salmonella. After overnight enrichment in
Efficiency of Plating Media and Enrichment Broths for Isolating Salmonella Species from Human Stool Samples: A Comparison Study
A comparative study was performed to evaluate best practice culture media and enrichment broths for recovering Salmonella species from human stool samples. A total of 1297 human stools were collected and processed in this study. Evaluation of agar media was carried out by direct plating (DP), 1096 stool samples were inoculated on Modified Semisolid Rappaport-Vassiliadis (MSRV), Xylose-Lysine-Deoxycolate (XLD), MacConkey (MAC), and Hektoen Enteric (HE) agars. Evaluation of enrichment broths were carried out by enrichment all 1297 stool samples in Selenite broth (SB), Rappaport-Vassiliadis (RV) broth, and Buffered Peptone Water (BPW), followed by plating on MSRV, MAC, and HE agars. A total of 102 Salmonella-positive stools by DP, 85.3% (87/102) were recovered utilizing MSRV while recovery from XLD, MAC, and HE agars were 34.3% (35/102), 34.3% (35/102), and 29.4% (30/102) respectively. A total 299/1297 stools samples were Salmonella-positive on at least one plating medium after enrichment procedure were 77

Designation of Salmonella enterica sp. nov., nom. rev., as the Type and Only Species of the Genus Salmonella: Request for an...
Since the publication of the Approved Lists of Bacterial Names, the type species of the genus Salmonella has been S. choleraesuis. At the time of publication of the Approved Lists, five Salmonella species had standing in the nomenclature, and the description of S. choleraesuis was the same as that of the serotype of that name. Several studies have shown that the genus Salmonella consists of only one species, and the strict application of the Bacteriological Code would recognize S. choleraesuis (the type species) as the single Salmonella species. This can lead to confusion and hazards since the specific epithet is also the name of a serovar (serovar Choleraesuis). This confusion is increased by the common practice of using serovar names as if they represented species names (e.g., S. typhi, S. choleraesuis, and S. typhimurium). Some serovars (e.g., Salmonella choleraesuis subsp. choleraesuis serovar Typhi) are highly pathogenic and cause a disease different from that caused by other serovars (e.g. S.

AU - Morningstar, Brenda R.. AU - Wünschmann, Arno. PY - 2012/12/14. Y1 - 2012/12/14. N2 - Snakes are considered to be a source of Salmonella infection for humans, but little is known about the actual serotype prevalence in healthy snakes over time. Twelve snakes involved in a public outreach program, representing seven different species, were tested weekly for shedding of Salmonella sp. over a period of 10 consecutive weeks. The snakes were housed in close proximity but in separate exhibits. Fresh fecal samples (when available) or cloacal swabs were cultured for Salmonella sp., and subsequent Salmonella isolates were serotyped. As representatives of the feed source, the feces of two mice and the intestines of one rat were cultured weekly. Fecal samples from 11 of the 12 snakes were positive for Salmonella at least ...

Course of immune responses generated by live Salmonella vaccine in pigs | Mitacs
Salmonella is the second most frequent cause of foodborne illness in Canada and pork is one of sources for human salmonellosis. Salmonella has also the potential to cause clinical disease in pigs. Salmonella is commonly found on Ontario swine farms. Thus control strategies should be implemented. Vaccination appears to be one of the most promising approaches. In Canada, there is currently available a live Salmonella Choleraesuis vaccine for use in pigs and a live Salmonella Typhimurium vaccine for use in poultry. However, the course of immune responses induced by the above vaccines in 11 pigs is not well studied. The objective of this proposal is to evaluate and compare the immune responses produced by these two Salmonella vaccines in pigs. This research can provide a better understanding of pig immune responses against Salmonella attenuated vaccines and will help to develop new vaccines for controlling Salmonella on Ontario swine farms.. ...
The role of two periplasmic copper- and zinc-cofactored superoxide dismutases in the virulence of Salmonella choleraesuis |...
Periplasmic copper- and zinc-cofactored superoxide dismutases ([Cu,Zn]-SODs, SodC) of several Gram-negative pathogens can protect against superoxide-radical-mediated host defences, and thus contribute to virulence. This role has been previously defined for one [Cu,Zn]-SOD in various Salmonella serovars. Following the recent discovery of a second periplasmic [Cu,Zn]-SOD in Salmonella, the effect of knockout mutations in one or both of the original sodC-1 and the new sodC-2 on the virulence of the porcine pathogen Salmonella choleraesuis is investigated here. In comparison to wild-type, while sodC mutants - whether single or double - showed no impairment in growth, they all showed equally enhanced sensitivity to superoxide and a dramatically increased sensitivity to the combination of superoxide and nitric oxide in vitro. This observation had its correlate in experimental infection both ex vivo and in vivo. Mutation of sodC significantly impaired survival of S. choleraesuis in interferon γ-stimulated

Salmonella - Academic Kids
Salmonella is a genus of rod-shaped Gram-negative enterobacteria that causes typhoid fever, paratyphoid and foodborne illness. Salmonella does not ferment lactose. It is motile in nature and produces hydrogen sulfide. Disease-causing salmonellae have recently been re-classified into a single species, Salmonella enterica, which has numerous strains or serovars. Salmonella typhi is a well known serovar that causes typhoid fever. Other salmonellae are frequent causes of foodborne illness, and can especially be caught from poultry and more generally from food that has been cooked or frozen, and not eaten straight away. In the mid to late 20th century, Salmonella enterica serovar Enteritidis was a common contaminant of eggs. This is much less common now with the advent of hygiene measures in egg production and the vaccination of laying hens to prevent samonella colonisation. Many different salmonella serovars also cause severe diseases in animals other than human beings. ...

Food safety, Salmonella - Raw Essentials | Real Food For Cats & Dogs
Many dogs and cats naturally carry Salmonella (mostly Salmonella typhimurium) in their digestive tracts. The report states that studies have found a 1-15% prevalence of Salmonella in the faeces of healthy dogs, and 1-18% in healthy cats.. According to the report, Salmonella is the most common food-borne bacteria. Around 1.4 million people in the U.S. contract Salmonella infections each year. About 1,000 of these die. About half of all Salmonella infections are from restaurants; and are often traced to infected, but asymptomatic, food handlers. Many of us have Salmonella infections and feel no ill effects. Meat, poultry, eggs, milk, fruits and vegetables can be contaminated with Salmonella. Processed foods can be easily infected in a contaminated plant. Recent food recalls for Salmonella have involved nuts, chocolate bars, peppers, and peanut butter. SALMONELLA INFECTION DOES NOT ALWAYS CAUSE ILL-HEALTH.

System Dynamics Simulation Model of Salmonella Contamination of Broile by Karen Dazo Galarneau
Salmonella has been studied and researched for more than a hundred years and yet it remains a problem for human and animal health. The goal of this dissertation was to apply the systems thinking approach to Salmonella contamination and develop a System Dynamics (SD) simulation model for Salmonella contamination in the chill tank of a poultry processing plant. But first the appropriate carcass rinse sampling method that would not impact on the resulting Salmonella contamination status of the broiler carcass was studied. Kappa agreement analysis was used to evaluate three sampling methods. The adjacent rinse method was found to be the best method. In the absence of actual data, literature data was used to develop a literature-based SD simulation model of Salmonella contamination of broiler carcasses in the chill tank. The literature-based SD model is the first application of system dynamics simulation modeling in the poultry-processing field. The model was able to show and simulate the dynamic and non
Animal Protein Producers - Check & Trace Salmonella
The first priority in case of a Salmonella contamination it to trace the source as soon as possible. To facilitate an efficient search it is good to know that different sources of Salmonella contamination are often associated with distinct Salmonella serotypes. Therefore, it is essential in any Salmonella reduction program to know which serotype is the culprit. The traditional Kauffmann-White method for confirming and serotyping Salmonella takes at least several days to obtain an end result. Also, up to 10 - 15% of cases yield inconclusive results. This is why Check-Points developed Check & Trace Salmonella, which overcomes these hurdles. It provides a rapid Salmonella confirmation and serotyping method based on DNA technology for routine use in any laboratory. With a single test - which can be performed in one day - it confirms the presence of Salmonella and identifies the serotype. If you suspect a Salmonella contamination in your poultry farm, Check & Trace Salmonella is the fastest and most ...

Salmonella on pig farm | CID LINES
Salmonellosis is a bacterial disease caused by strains of Salmonella. It occurs in animals and humans. In both cases it is an enteric disease of varying severity, usually involving diarrhoea. With pigs, however, most Salmonella infections are without symptoms. Salmonella infection is a Public Health Concern. Many strains of Salmonella are zoonotic agents, spreading to man from contaminated animal origin food products. In humans Salmonellosis is one of the most common causes of food poisoning. The commonest serotypes causing disease in humans are Salmonella Enteritidis and Salmonella Typhimurium. National control measures, often including legislation, have been implemented in many countries. In the European Union the Zoonoses Directive (EC/2003/2160) was enacted in 2003 to minimize Salmonella infection in pigs.. ...

A new photonics biosensor configuration comprising a Double-side Ring Add-drop Filter microring resonator (DR-ADF) made from SiO2-TiO2 material is proposed for the detection of Salmonella bacteria (SB) in blood. The scattering matrix method using inductive calculation is used to determine the output signals intensities in the blood with and without presence of Salmonella. The change in refractive index due to the reaction of Salmonella bacteria with its applied antibody on the flagellin layer loaded on the sensing and detecting microresonator causes the increase in through and dropper ports intensities of the output signal which leads to the detection of SB in blood. A shift in the output signal wavelength is observed with resolution of 0.01 nm. The change in intensity and shift in wavelength is analyzed with respect to the change in the refractive index which contributes toward achieving an ultra-high sensitivity of 95,500 nm/RIU which is almost two orders higher than that of reported from single
FDA alert warns pet owners of Salmonella contamination in raw food | LexBlog
Food contaminated with Salmonella bacteria does not usually look, smell, or taste spoiled. Anyone can become sick with a Salmonella infection. Infants, children, seniors, and people with weakened immune systems are at higher risk of serious illness because their immune systems are fragile, according to the CDC.. Anyone who has eaten any of the recalled products and developed symptoms of Salmonella infection should seek medical attention. Sick people should tell their doctors about the possible exposure to Salmonella bacteria because special tests are necessary to diagnose salmonellosis. Salmonella infection symptoms can mimic other illnesses, frequently leading to misdiagnosis.. Symptoms of Salmonella infection can include diarrhea, abdominal cramps, and fever within 12 to 72 hours after eating contaminated food. Otherwise, healthy adults are usually sick for four to seven days. In some cases, however, diarrhea may be so severe that patients require hospitalization.. Older adults, children, ...

FSIS policy, precedent means Salmonella petition faces tough sledding | LexBlog
A petition to USDAs Food Safety and Inspection Service asking for the listing of 31 Salmonella strains as meat and poultry adulterants raises a question. How did FSIS respond the last time someone wanted to list Salmonella as an adulterant?. That someone was the Center for Science in the Public Interest, which spent much of the past decade trying to persuade FSIS to declare four Salmonella strains as adulterants because they are antibiotic-resistant (ABR) strains. The four ABRs are: Hadar, Heidelberg, Newport, and Typhimurium.. The new petition, filed Sunday by food safety attorney Bill Marler, asks FSIS to declare adulterant status for the four ABS strains and 27 others that he calls the Salmonella Outbreak Serotypes.. They are: Salmonella Agona, Anatum, Berta, Blockely, Braenderup, Derby, Dublin, Enteritidis, Hadar, Heidelberg, I 4,,12:i:-, Infantis, Javiana, Litchfield, Mbandaka, Mississippi, Montevideo, Muenchen, Newport, Oranienburg, Panama, Poona, Reading, Saintpaul, Sandiego, ...

The GeneChip Porcine Genome Array was used to identify the transcriptional response upon either Salmonella typhimurium (ST) or Salmonella choleraesuis (SC) infection in two porcine epithelial cell lines (IPEC-J2, from jejunum and IPI-2I, from ileum) during 2 and 4 hours post infection. The objectives in this study were first, to identify the different response between the epithelial cell lines from different gut regions; second, to study how the Salmonella serotypes used could elicit a different host response; and third, to determine the effect of the time-points on the differentially gene expression. Overall design: Epithelial cells were seeded into 6-well tissue culture plates and grown to confluence in 5% CO2 at 37ºC. Monolayers were infected for 1 h. with Salmonella typhimurium or Salmonella choleraesuis serotypes (MOI 1:10) or incubated with media alone (Control cells). Extracellular bacteria were removed, and cultures were further incubated during 2 and 4 h. in the presence of 50 µg/ml of the

FREE Preventing and Treating Salmonella Infections Essay
Salmonella caused by an infectious agent (pathogen) that is called Salmonella enteriditis. The bacteria is larger than a virus; but, is visible with a microscope. It is a microscopic living creature that passes from the feces of people or animals to others. It has been causing illnesses for over 100 years. It infects the cell, multiples within it then bursts the cell. Special effect protein factors are required for salmonella intestinal invasion and the induction of fluid secretion and inflammatory responses. Salmonella is most common in birds, mainly poultry. Newborn calves are also susceptible to the bacteria. The feces from the dam could get in the mouth of the calf after being born. Salmonella enteritidis and Salmonella enteric are which causes human disease. Salmonellosis spreads to people by ingestion of Salmonella bacteria that is from contaminated food. Salmonella is worldwide and can contaminate almost any food type, but outbreaks of the disease have highly involved raw eggs, raw meat, ...

INFECTION-IMMUNITY IN EXPERIMENTAL SALMONELLOSIS | JEM
Salmonella enteritidis is highly virulent for the mouse causing an infection resembling mouse typhoid. Survivors of the infection are completely resistant to reinfection and eliminate a large challenge dose of virulent organisms within 72 hr. The antigenically related Salmonella gallinarum was almost avirulent for the mouse but animals vaccinated with this organism were equally capable of eliminating a lethal dose of virulent S. enteritidis. Living Salmonella pullorum, on the other hand, was quickly eliminated from the tissues of normal mice. Vaccination with this organism failed to evoke an effective bactericidal mechanism. Alcohol-killed vaccines of these three Salmonellae all produced an increase in blood clearance rate, but gave only marginal protection against S. enteritidis. Liver and spleen counts on these mice revealed a 1 to 2 day delay before any net increase in the total bacterial population could be observed. Immunization of mice with increasing doses of living Salmonella montevideo ...

Multidrug resistant (MDR) Salmonella are a leading cause of foodborne diseases and serious human health concerns worldwide. In this study we detected MDR Salmonella in broiler chicken along with the resistance genes and class 1 integron gene intl1. A total of 100 samples were collected from broiler farms comprising 50 cloacal swabs, 35 litter and 15 feed samples. Overall prevalence of Salmonella was 35% with the highest detected in cloacal swabs. Among the Salmonella, 30 isolates were confirmed as S. enterica serovar Typhimurium using molecular methods of PCR. Disk diffusion susceptibility test revealed that all the Salmonella were classified as MDR with the highest resistance to tetracycline (97.14%), chloramphenicol (94.28%), ampicillin (82.85%) and streptomycin (77.14%). The most prevalent resistance genotypes were tetA (97.14%), floR (94.28%), blaTEM-1 (82.85%) and aadA1 (77.14%). In addition, among the MDR Salmonella, 20% were positive for class 1 integron gene (intl1). As far as we know, this is

Salmonella - LABOKLIN GMBH & CO.KG LABOR FÜR KLINISCHE DIAGNOSTIK
Salmonella belong to the family Enterobacteriaceae and are found in the intestines of animals and humans. In most cases, infection occurs faecal-orally or by feeding raw meat. Salmonella infections affect almost all animal species. Compared to herbivorous pets, dogs and cats are more resistant to salmonella infections. Under favourable conditions, salmonellosis causes diarrhoea with vomiting and fever; in young animals, the disease can also become septicaemic. In reptiles and amphibians, salmonella can be part of the normal intestinal flora. In these animals, clinically relevant salmonelloses are associated with immune deficiency. According to the Robert Koch Institute (RKI), about 10% of all human salmonella infections, which cause diarrhoea, are related to direct contact with excreting dogs, cats and particularly reptiles. For some time now, ESBL producers have also been detected among salmonella, especially in livestock. Because of the ESBL problem, creating an antibiogram is essential. In ...
Survival of inoculated Salmonella on the shell of hens eggs and its potential significance : WestminsterResearch
The aim of this research was to evaluate the risk of inoculated Salmonella persisting on the outside of the shell of hens eggs. Hens eggs were surface inoculated with a cocktail of Salmonella strains and stored for up to 54 days at 4, 10 and 20 °C and at 80 and 90% relative humidity. Salmonella survival showed an irregular pattern, with extremes of high recovery and no recovery. However, salmonellae were always recovered after resuscitation. Monte Carlo simulation of different scenarios using relevant assumptions indicated that the distribution of surviving Salmonella was skewed towards low numbers, suggesting higher chances of Salmonella persisting on the eggs in low numbers (,104 cfu egg−1). Although numbers were low, the research demonstrated the ability of salmonellae to survive on the shells of eggs following contamination and this clearly has safety implications for handling of eggs in the food industry and the domestic environment. ...

Salmonella choleraesuis was the most invasive serotype observed. S. panama, S. typhimurium and S. schwarzengrund were the commonest causes of EII among those serotypes usually causing gastroenteritis. Pre-existing underlying disease, particularly immunosuppressive disease, was the most important risk factor that may have predisposed adult patients to have EII. Old age (≥ 60 years) and isolation of invasive serotypes were also frequently associated with EII in adult patients. The ...

Control of Invasive Salmonella Disease in Africa: Is There a Role for Human Challenge Models? - Oxford Vaccine Group
Invasive Salmonella disease in Africa is a major public health concern. With evidence of the transcontinental spread of the Salmonella Typhi H58 haplotype, improved estimates of the burden of infection and understanding of the complex interplay of factors affecting disease transmission are needed to assist with efforts aimed at disease control. In addition to Salmonella Typhi, invasive nontyphoidal Salmonella are increasingly recognized as an important cause of febrile illness and mortality in sub-Saharan Africa. Human experimental oral challenge studies with Salmonella can be used as a model to offer unique insights into host-pathogen interactions as well as a platform to efficiently test new diagnostic and vaccine candidates. In this article, we review the background and use of human challenge studies to date and discuss how findings from these studies may lead to progress in the control of invasive Salmonella disease in Africa.
Salmonella enterica subsp. enterica isolated from chicken carcasses and environment at slaughter in Reunion Island: prevalence,...
Salmonella contamination of 71 chicken broiler flocks was investigated at the slaughterhouse in Reunion Island between October 2007 and January 2009. Samples were collected from live broiler chickens and chicken carcasses as well as the slaughterhouse environment. Salmonella spp. was isolated from 40 of 71 (56 % with a confidence interval 5 % [45-67]) broiler chicken flocks at slaughter. The most prominent serovars were Blockley (31 %), Typhimurium and Brancaster (14 %), Hadar (10 %), Salmonella multidrug resistant clinical organisms serotypes 1,4,,12:i:-, and Virchow (8 %) and Livingstone, St. Paul, Seftenberg, Llandoff, Infantis and Indiana. At the farm, 27 % of the broiler chicken flocks tested positive for Salmonella spp. Salmonella spp. was isolated from 124 of 497 environmental samples (25 %). In most cases, there was no relationship between pulsed field gel electrophoresis (PFGE) pattern and antibiotic resistance pattern. The predominant Salmonella serovars were susceptible to most of the

ISSN 1678-9946. http://dx.doi.org/10.1590/S0036-46651996000500001.. Serovars of a total of 5,490 Salmonella strains isolated during the period of 1991-95, from human infections (2,254 strains) and from non-human materials (3,236 strains) were evaluated. In the studied period, 81 different serovars were determined among human isolates. Salmonella Enteritidis corresponded to 1.2% in 1991, 2% in 1992, 10.1% in 1993, 43.3% in 1994, and 64.9% in 1995 of all isolates. A significant rise on the isolation of this serovar was seen since 1993 linked to food poisoning outbreaks. It is reported also an increase on the isolation of S. Enteritidis from blood cultures, associated mainly with patients with immunodeficiency syndrome. S. Enteritidis was prevalent among one hundred and thirty different serovars isolated ...
EFSA assesses risk of Salmonella from pig meat | European Food Safety Authority
The Panel found evidence suggesting that the human cases attributable to Salmonella in pig meat will mainly depend on the levels of Salmonella in pigs and pig meat, as well as on consumption patterns and the relative importance of the other sources of Salmonella.. The Panel evaluated a series of measures to reduce the number of human cases of Salmonella. These included ensuring pigs in breeding holdings are free from Salmonella, ensuring that the feed is also free from Salmonella, adequate cleaning and disinfection of holdings, avoiding contamination during slaughter, and decontaminating carcasses. The Panel indicated that these measures should be used in combination and based on the individual situation of each Member State; and that a hundredfold reduction of the number of Salmonella bacteria on contaminated carcasses would result in a 60-80% reduction of the cases of human salmonellosis originating from pig meat consumption.. The experts also indicated that in order to reduce Salmonella in ...
Growth and Survival of Listeria monocytogenes and Salmonella on Whole and Sliced Cucumbers - PubAg
Cucumbers were associated with four multistate outbreaks of Salmonella in the United States between 2013 and 2016. This study evaluated the fate of Listeria monocytogenes and Salmonella on whole and sliced cucumbers at various storage temperatures. Cucumbers were inoculated with five-strain cocktails of L. monocytogenes or Salmonella, air dried, and stored at 23 ± 2, 4 ± 2, and −18 ± 2°C. Whole and sliced cucumber samples were enumerated on nonselective and selective media at 0, 0.21, 1, 2, 3, and 4 days (23 ± 2°C); 0, 1, 2, 3, 7, 14, and 21 days (4 ± 2°C); and 0, 7, 28, 60, 90, and 120 days (−18 ± 2°C). For Salmonella, additional time points were added at 8 and 17 h (23 ± 2°C) and at 17 h (4 ± 2°C). Population levels were calculated for whole (CFU per cucumber) and sliced (CFU per gram) cucumbers. Both pathogens grew on whole and sliced cucumbers held at ambient temperatures. At 23 ± 2°C, L. monocytogenes and Salmonella populations significantly increased on whole (2.3 and ...
Frontiers | Study of Salmonella Typhimurium Infection in Laying Hens | Microbiology
Members of Salmonella enterica are frequently involved in egg and egg product related human food poisoning outbreaks worldwide. In Australia, Salmonella Typhimurium is frequently involved in egg and egg product related foodborne illness and Salmonella Mbandaka has also been found to be a contaminant of the layer farm environment. The ability possessed by Salmonella Enteritidis to colonise reproductive organs and contaminate developing eggs has been well described. However, there are few studies investigating this ability for Salmonella Typhimurium. The hypothesis of this study was that the Salmonella Typhimurium can colonise the gut for a prolonged period of time and that horizontal infection through feces is the main route of egg contamination. At 14 weeks of age hens were orally infected with either S. Typhimurium PT 9 or S. Typhimurium PT 9 and Salmonella Mbandaka. Salmonella shedding in feces and eggs was monitored for 15 weeks post infection. Egg shell surface and internal contents of eggs laid

Outbreaks of Human Salmonella Infections Associated with Live Poultry, United States, 1990-2014 - Volume 22, Number 10-October...
Backyard poultry flocks have increased in popularity concurrent with an increase in live poultry-associated salmonellosis (LPAS) outbreaks. Better understanding of practices that contribute to this emerging public health issue is needed. We reviewed outbreak reports to describe the epidemiology of LPAS outbreaks in the United States, examine changes in trends, and inform prevention campaigns. LPAS outbreaks were defined as ≥2 culture-confirmed human Salmonella infections linked to live poultry contact. Outbreak data were obtained through multiple databases and a literature review. During 1990-2014, a total of 53 LPAS outbreaks were documented, involving 2,630 illnesses, 387 hospitalizations, and 5 deaths. Median patient age was 9 years (range <1 to 92 years). Chick and duckling exposure were reported by 85% and 38% of case-patients, respectively. High-risk practices included keeping poultry inside households (46% of case-patients) and kissing birds (13%).

Thomson International Onions Linked to Salmonella Newport Outbreak
Noted food safety attorney Fred Pritzker, who has represented many clients sickened with Salmonella infections in lawsuits, said, When produce is eaten without a kill step, it is critical that growers, processors, and producers are confident those products are not contaminated with pathogens. Now hundreds of people are sick in two countries just because they bought red onions or ordered food made with that product in restaurants.. In the U.S. outbreak, many ill people are in lines clusters, which are two more more people who dont live in the same household who ate at the same restaurant, attended a common event, or shopped at the same grocery store before they got sick. Twenty-two illness clusters have been identified in seen states. Many of the people in those clusters ate red onions.. The traceback information collected from those clusters identified Thomson International of Bakersfield, California as a likely source of red onions. Because of the way onions are grown and harvested, other ...
Identification of a virulence locus encoding a second type III secretion system in Salmonella typhimurium | PNAS
Mapping the insertion points of 16 signature-tagged transposon mutants on the Salmonella typhimurium chromosome led to the identification of a 40-kb virulence gene cluster at minute 30.7. This locus is conserved among all other Salmonella species examined but is not present in a variety of other pathogenic bacteria or in Escherichia coli K-12. Nucleotide sequencing of a portion of this locus revealed 11 open reading frames whose predicted proteins encode components of a type III secretion system. To distinguish between this and the type III secretion system encoded by the inv/spa invasion locus known to reside on a pathogenicity island, we refer to the inv/spa locus as Salmonella pathogenicity island (SPI) 1 and the new locus as SPI2. SPI2 has a lower G+C content than that of the remainder of the Salmonella genome and is flanked by genes whose products share greater than 90% identity with those of the E. coli ydhE and pykF genes. Thus SPI2 was probably acquired horizontally by insertion into a ...
Salmonella - Simple English Wikipedia, the free encyclopedia
Salmonella is a genus of bacteria. It is a major cause of illness throughout the world. The bacteria are generally passed on to humans by eating or drinking food of animal origin which has the bacteria in it, mainly meat, poultry, eggs and milk. Bacteria from the genus Salmonella can cause diseases, such as diarrhea, cholera and typhus. These bacteria are zoonotic, meaning they can infect both animals and humans.. Salmonella is closely related to the Escherichia genus and are found worldwide in cold- and warm-blooded animals (including humans), and in the environment. They cause illnesses like typhoid fever, paratyphoid fever, and foodborne illness.. Salmonella is also extremely dangerous, and like most diseases, weaker humans like the old and young could easily die from it. Salmonella can only be killed in food by cooking at high temperatures. This is called denatured.. ...
Salmonella infection acquired from reptilian pets | Archives of Disease in Childhood
Salmonella species are widely distributed in animals and most infections in humans are acquired from eating contaminated foodstuffs. Salmonella serotypes of subgroups III and IV are found in reptiles such as turtles, terrapins, lizards, and snakes. Infections of humans associated with handling these animals have been regularly described.1 Terrapins and turtles were first implicated as vectors of salmonellosis, particularly of Salmonella java.These reptiles were popular as domestic pets in the 1970s and 1980s and were noted then to cause infections, particularly in children.2 After a series of outbreaks public health measures were introduced for the care and management of terrapins.3 Iguanas are now popular as exotic pets, especially in the USA. Their association with salmonella infection in young children has been noted by paediatricians in that country. A study in Colorado implicated green iguanas in five cases of salmonella infection in children. The same rare serotype was isolated from ...

S. enterica. • S. bongori Salmonella enterica, which is of the greatest public health concern, is comprised of six subspecies:. o S. enterica subsp. enterica (I). o S. enterica subsp. salamae (II). o S. enterica subsp. arizonae (IIIa). o S. enterica subsp. diarizonae (IIIb). o S. enterica subsp. houtenae (IV). o S. enterica subsp. indica (VI). Salmonella is further subdivided into serotypes, based on the Kaufmann-White typing scheme first published in 1934, which differentiates Salmonella strains by their surface and flagellar antigenic properties. Salmonella spp. are commonly referred to by their serotype names. For example, Salmonella enterica subsp. enterica is further divided into numerous serotypes, including S. Enteritidis and S. Typhimurium, which are common in the U.S. (Note that species names are italicized, but serotype names are not.). When Kaufmann first proposed the scheme, 44 serotypes had been discovered. As of 2007, the number of serotypes discovered was 2,579.. 2. ...
Genetic surveillance of endemic bovine Salmonella Infantis infection
Background: Salmonella serovar Infantis is endemic in Finnish food-producing animals since the 1970s. The purpose of this study was to describe the molecular epidemiology of the infection in cattle during 1985-2005, to follow the persistence of the feed-related outbreak strain from 1995 in the cattle population, and to analyse the stability of XbaI-banding patterns in individual herds during long-lasting infections. Methods: Salmonella Infantis isolates from 478 cattle herds (n = 588), covering 73% of the subclinically or clinically infected herds, were typed by pulsed-field gel electrophoresis (PFGE) using XbaI. DNA fragments larger than 125 kb were counted in PFGE types because of high plasmid background. Ribotyping and IS200-typing with BanI-digested DNA were done on 57 selected isolates. Results: The isolates associated with the infection consisted of 51 PFGE types with genetic similarity (F value) between 0.58 and 0.95. From 1985 to 2003, the major type appeared on 68% of the farms. The ...
Prime-boost vaccination with attenuated Salmonella Typhimurium ΔznuABC and inactivated Salmonella Choleraesuis is protective...
Salmonellosis is a public health problem primarily caused by consumption of pork products contaminated with S. Typhimurium . On the contrary, S. Choleraesuis, a host-adapted serovar in pigs, causes a typhoid-like disease in piglets, which is characterized by reduced growth and, in the most severe cases, a high mortality rate, and hence mainly representing an economic problem [1, 18]. S. Choleraesuis is not considered to be a major agent of zoonotic infections, although some cases of human infection have been recorded, especially in Asia .. Vaccination of pigs could represent a valid control system in countries with a high prevalence of salmonellosis in animals. Attenuated vaccines are more effective than inactivated ones in protecting against enteric diseases, due to their ability to induce cell-mediated and mucosal immunity . To address this issue, in previous study we assessed the safety and efficacy of S. Typhimurium ΔznuABC strain in different models of infection [11-16]. In the ...
Human Salmonella Reduced by Almost One-Half | The Poultry Site
To combat human salmonellosis it is important to reduce Salmonella in animals and derived products so that food is safer for consumers.. In 2003, the EU set up comprehensive control measures for zoonoses, considering Salmonella as a priority. Enhanced Salmonella programmes in poultry were implemented in all EU Member States and targets were set for reducing the bacteria in poultry flocks (laying hens, broilers and turkeys).. To support the reduction of Salmonella in the food chain, EFSA has advised on the risks for public health from infected animals and provided recommendations and advice on control and reduction measures, such as reduction targets in poultry and poultry meat and the use of vaccines and antimicrobials for the control of Salmonella.. EFSA has also evaluated the impact of different control measures for Salmonella in pigs.. EFSA has assisted decision-makers by analysing the results of EU-wide baseline surveys on the prevalence of Salmonella in food and food-producing animals, ...
Validation of baking to control Salmonella serovars in hamburger bun manufacturing, and evaluation of Enterococcus faecium ATCC...
With the implementation of the Food and Drug Administrations Food Safety Modernization Act, the food industry must scientifically verify that current production processes provide sufficient protection against pathogens. This study was conducted to validate a simulated commercial baking process for hamburger buns to control Salmonella spp. contamination and to determine the appropriateness of using non-pathogenic surrogates (Enterococcus faecium ATCC 8459 or Saccharomyces cerevisiae) for in-plant process validation studies. Wheat flour was separately inoculated (~6 log CFU/g) with three Salmonella serovars (Typhimurium, Newport or Senftenberg) or E. faecium. Dough was formed, proofed, and baked to mimic commercial manufacturing conditions. Non-inoculated dough was used to evaluate S. cerevisiae (Bakers yeast) survival during baking. Buns were baked for 9, 11 and 13 min in a conventional oven set at 218°C, with internal bun temperature profiles recorded. Salmonella serovars and S. cerevisiae ...

Another Resistant Salmonella Strain Emerges | Food Safety News
In a study published online Wednesday in the Journal of Infectious Diseases, an international team of researchers led by Frances Pasteur Institute describes the emergence of a multidrug-resistant strain of Salmonella, this one a variant of S. Kentucky.. The new strain is highly resistant to several antimicrobials, notably ciprofloxacin, the main antibiotic used to treat severe cases of Salmonella poisoning. Ciprofloxacin is part of the fluoroquinolone class of antibiotics, the report explains.. The scientists say the highly resistant Salmonella Kentucky, which likely emerged in Africa, infected 489 people in France, England, Wales and Denmark between 2000 and 2008, and has turned up in imported spices in North America.. While S. Kentucky is the most common Salmonella serotype found in U.S. poultry, it has caused few illnesses, the report notes. But the scientists theorize that widespread use of fluoroquinolones in Nigeria and Morocco may have helped this variant develop drug resistance. ...
Salmonella can often be found in the intestinal tract of reptiles. A reptile with Salmonella can possibly infect its owner.Salmonella in iguanas is a health problem that can affect their owners sometimes more than the reptile itself. Beneficial bacteria, known as probiotics, have long been known to aid the intestinal tract of humans. Now a product is available for salmonella-positive reptiles. Many reptile-related diseases can be traced to the health of the reptiles intestinal tract. A good, well-balanced probiotic offers a safe approach for the gut of reptiles. Many have said that the use of NutriBAC has increased their reptiles appetite, reversed constipation, and stopped regurgitation following feedings. A good probiotic or beneficial bacteria, like NutriBAC, is simply a tool in the husbandry of reptiles and amphibians. NutriBAC is the only probiotic patented for use in reptiles and amphibians ...

Salmonella vaccine will be commercialized in new partnership | Wellness General
If manufacturers have access to a multi-strain salmonella vaccine to immunize poultry processed for consumption, it could mark the start of an important change for the food and beverage industry.. The USDA identified salmonella as the leading cause of bacterial foodborne illness in the U.S., causing about 1.2 million illnesses annually. Although salmonella is transferrable through a range of commercially manufactured products, poultry is a particularly well-known carrier of this infection.. There is no single strain of salmonella that causes a foodborne illness, but the most common strain is salmonella enteritidis. The rate of illness for this bacteria hasnt dropped in more than 10 years, researchers from the USDAs Food Safety and Inspection Service noted. In fact, salmonella, cyclospora and campylobacter infections were up in 2018 compared to previous years, but the jump might be partly due to the wider use of culture-independent diagnostic tests, according to new research published by the ...

In more serious, rare cases, salmonella spreads through the intestines and blood stream and throughout the body, prompting an emergency situation. Young children, the elderly, and those with compromised immune systems are the most likely to have severe infections. Contact your doctors if you are showing symptoms.. Consumers are ...
Identification of drug-resistant Salmonella from food handlers at the University of Gondar, Ethiopia | BMC Research Notes |...
Salmonella species are among the most common food borne pathogens worldwide and their infection is one of the major global public health problems. During the last decade, multidrug-resistant Salmonella species have increased to a great deal, especially in developing countries. The prevalence and antimicrobial susceptibility pattern of Salmonella isolates among food handlers at the University of Gondar, Ethiopia, were described in the current investigation. A cross-sectional study was conducted from February to June, 2013 at the University of Gondar. Stool samples from selected volunteer food handlers were collected and analyzed complemented with questionnaire. Standard isolation, identification and biochemical tests were performed to identify Salmonella isolates. Antimicrobial susceptibility tests were also carried out on each isolate using Kirby-Bauer disc diffusion method. The data was entered into Epi info version 3.5.4 and analyzed using SPSS version 21. Out of 423 food handlers participated, 303(71
Molecular diversity and antibiotic resistance gene profile of Salmonella enterica serovars isolated from humans and food...
Outbreaks of Salmonellosis remain a major public health problem globally. This study determined the diversity and antibiotic resistance gene profile of Salmonella enterica serovars isolated from humans and food animals. Using standard methods, Salmonella spp. were isolated from fecal samples, profiled for antimicrobial susceptibility and resistance genes. Seventy-one Salmonella isolates were recovered from both humans and food animals comprising cattle, sheep, and chicken. Forty-four serovars were identified, with dominant Salmonella Budapest (31.8%). Rare serovars were present in chicken (S. Alfort, S. Wichita, S. Linton, S. Ealing, and S. Ebrie) and humans (S. Mowanjum, S. Huettwillen, S. Limete, and S. Chagoua). Sixty-eight percent of isolates were sensitive to all test antibiotics, while the highest rate of resistance was to nalidixic acid (16.9%; n = 12), followed by ciprofloxacin (11.3%; n = 8) and tetracycline (9.9%; n = 8). Five isolates (7%) were multidrug-resistant and antimicrobial ...
Antibiotic resistance and molecular characterization of the hydrogen sulfide-negative phenotype among diverse Salmonella...
Among 2179 Salmonella isolates obtained during national surveillance for salmonellosis in China from 2005 to 2013, we identified 46 non-H2S-producing strains originating from different sources. The isolates were characterized in terms of antibiotic resistance and genetic variability by pulsed-field gel electrophoresis and multilocus sequence typing. Mutation in the phs operon, which may account for the non-H2S-producing phenotype of the isolated Salmonella strains, was performed in this study. Among isolated non-H2S-producing Salmonella strains, more than 50% were recovered from diarrhea patients, of which H2S-negative S. Gallinarum, S. Typhimurium, S. Choleraesuis and S. Paratyphi A isolates constituted 76%. H2S-negative isolates exhibited a high rate of resistance to ticarcillin, ampicillin, and tetracycline, and eight of them had the multidrug resistance phenotype. Most H2S-negative Salmonella isolates had similar pulsed-field gel electrophoresis profiles and the same sequence type as H2S-positive

ASMscience | Salmonella spp.: Masters
This chapter highlights recent progress made toward understanding the molecular basis of Salmonella-induced enteritis. Information is scarce on the specific course of events following nontyphoidal Salmonella infection in humans because most infected individuals are rarely hospitalized. As such, observations of nontyphoidal Salmonella infection have mostly come from patients admitted to the hospital with severe fatal infections. Interactions between bacteria and intestinal tissue were examined in starved, opium-treated guinea pigs several hours after oral challenge with 108 invasive serovar Typhimurium. This study found that Salmonella closely contacts the epithelial cells lining the intestine, primarily the ileum, and thereafter elicits the local degeneration of filamentous actin in apical microvilli and the underlying terminal web. More recently, studies have turned to the use of cattle to model the pathophysiology of Salmonella-induced enteritis in humans. Following nitrogen mustard administration,
Prevalence, serotype distribution, and antimicrobial resistance of Salmonella isolated from food products in Morocco |...
Introduction: Salmonellosis is one of the most common foodborne diseases worldwide. The irrational use of antibiotics in medicine and in animal feed has greatly promoted the emergence and spread of resistant strains of non-typhoidal Salmonella.. Methodology: A total of 464 food products were collected in Tetouan from January 2010 to December 2012. The isolation and identification of Salmonella were performed according to Moroccan standard 08.0.116. All isolates were serotyped and were then tested for antibiotic resistance using the disk diffusion method.. Results: The microbiological analysis showed that 10.3% of food samples were contaminated with Salmonella. Eleven serotypes were identified: Kentucky 22.9% (11/48), Agona 16.7% (8/48), Reading 12.5% (6/48), Corvallis 8.3% (4/48), Saintpaul 8.3% (4/48), Typhimurium 6.2% (3/48), Montevideo 6.2% (3/48), Enteritidis 4.2% (2/48), and 2% (1/48) for each of Israel, Hadar, and Branderup.. Drug susceptibility testing showed that 39.6% of Salmonella were ...
