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
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
This study reports the identification of Salmonella serotypes in meat samples submitted to the Veterinary Research Institute (VRI) for diagnosis. A total of 425 Salmonella isolates were received from the Veterinary Public Health Laboratory and Regional Veterinary Laboratories, Malaysia from January to December 2009. All were serotyped for Salmonella serotypes using Kauffmann- White classification scheme. Out of the total, 31 different serotypes were identified from buffalo, beef, poultry and pork meat. The dominant serotypes identified were S. Typhimurium (12.7%), followed by S. Enteritidis (12.5%), S. Corvallis (11.6%), S. Senftenberg (11.1%) and S. Indiana (8.1%).

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.
A lethal strain of salmonella thats resistant to at leastnine antibiotics is spreading rapidly across the US. Representative Henry Waxman, D-CA, says multi-drug-resistant salmonella Newport is a growing and serious threat, and has sent a warning letter to the Dept. of Agriculture.. Salmonella can be caught from improperly stored food and rawchicken. Its found on dairy farms and lives in undercookedhamburger and cheese made from unpasteurized milk. It causesdiarrhea, abdominal pain, fever, bloody stools and vomiting,and is most dangerous to very young children, the elderlyand those with other illnesses.. Last year, at least seven outbreaks affected more than 100people. This year, 129 people have become sick, and one, aNew York leukemia patient, died after the salmonella causeda massive bloodstream infection. Salmonella Newport accounts for about 10% of the estimated1.4 million U.S. cases of salmonella poisoning each year.26% of salmonella Newport bacteria are multi-drug resistant,up from 1% ...

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.. ...
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 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. ...

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. MANY CARRIERS OF SALMONELLA SHOW NO SYMPTOMS OF DISEASE. ...
Epi Curves: Multistate Outbreak of Multidrug-Resistant Salmonella Heidelberg Infections Linked to Foster Farms Brand Chicken (Final Update)
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
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 ...

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
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, ...

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,[5],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

Rappaport Vassiliadis R10 Broth is used for the selective enrichment of Salmonella spp. from foods in a laboratory setting. Rappaport Vassiliadis R10 Broth is not intended for use in the diagnosis of disease or other conditions in humans.. Rappaport et al formulated an enrichment medium for Salmonella spp. that was modified by Vassiliadis et al. The Rappaport formulation, designated R 25/37°C, recommended incubation at 37°C. The Vassiliadis modification, designated R 10/43°C, had a reduced level of Malachite Green and recommended incubation at 43°C. Peterz later showed that incubation at 41.5 ± 0.5°C for 24 hours improved recovery of Salmonella spp. Rappaport-Vassiliadis R10 Broth is a selective enrichment medium that is used following pre-enrichment of the specimen. It has gained approval for use in analyzing milk and milk products, raw flesh foods, highly contaminated foods, and animal feeds. This medium selectively enriches for Salmonella spp. because bacteria, including other ...
Nontyphoidal Salmonella organisms cause 1.4 million illnesses annually, 95% of which are thought to be foodborne.16 It is estimated that 600 deaths occur annually from Salmonella infections, primarily among the elderly and very young.16 More than one third of all cases occur in children younger than 10 years,18 and the incidence in children younger than 1 year is 10 times higher than in the general population (128.9 vs 12.4 per 100 000).17 Ten percent of blood and central nervous system infections caused by Salmonella species as reported to the Centers for Disease Control and Prevention occur in children younger than 1 year.26 Children of all ages with chronic conditions such as sickle cell anemia are at high risk of serious complications from infections with Salmonella species.27. The dissemination of resistant Salmonella infections through the food chain is well documented. A 6-state outbreak of plasmid-mediated, multidrug-resistant Salmonella newport infection attributed to consumption of ...
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, ...

Abstract: This work reports for the first on the prevalence of Escherichia coli and Salmonella spp. in beef sold in the Tamale Metropolis. The conventional method was used to isolate Escherichia coli and Salmonella spp. from beef samples sold at the Tamale Metropolis. Seventy beef samples were obtained from seven different locations where meat is popularly sold in the Tamale Metropolis and analyzed microbiologically for Escherichia coli and Salmonella spp. by following procedures in the Bacteriological Analytical Manuel of the FDA-USA. The average prevalence of Escherichia coli was 56% and was highest in Location G (100%), followed by Location C (80%), Locations D and F (60%), Location B (50%) and Location E (40%). Escherichia coli was not isolated from Location A. The overall prevalence of Salmonella spp. in the beef samples was 31%. The location with the highest prevalence of Salmonella spp. was Location F (90%), followed by Location D (50%), Location E (30%) and Location C (20%). Locations A, ...

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

Group-A cows were inoculated orally, or inoculated orally and then IV, but none became a S dublin carrier. As expected, all 7 group-A cows responded with a marked increase in ELISA titer ...
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 ...
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. ...

N2 - To identify the risks and predictors for extraintestinal infection (EII) in patients with non-typhoidal salmonellosis, we undertook a study of 398 patients with cultures positive for non-typhoidal Salmonella seen at Chang Gung Memorial Hospital and Chang Gung Childrens Hospital between November 1993 and October 1994. 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 ...

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 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,[5],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 ...
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 ...
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 ...
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
A total of 136,915 unique blood cultures were obtained over the seven years period and total positive cultures were 17,494 (13%).

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%).

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 ...
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[1] 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.[2]. 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 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. ...
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 ...
Salmonellosis is a public health problem primarily caused by consumption of pork products contaminated with S. Typhimurium [2]. 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 [8].. 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 [19]. 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 ...
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, ...
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 outbreak of a very rare type of Salmonella bacteria, called Salmonella Nchanga, has been occurring at the same time as the Salmonella Bareilly outbreak. Based on patient interviews, and because 50% of the patients with the new type of bacteria also consumed raw sushi before becoming ill, the CDC is combining the Salmonella Bareilly investigation with the Salmonella Nchanga investigation.. FDA laboratories and two laboratories in Wisconsin have matched the two types of Salmonella taken from the raw tuna samples to the bacteria taken from stool samples of the patients.. The CDC has put together advice to consumers that anyone who eats sushi or other raw fish products should read.. Map provided courtesy of the CDC. ...
FOR IMMEDIATE RELEASE - April 30, 2012 - Diamond Pet Foods is expanding a voluntary recall to include Diamond Puppy Formula dry dog food. The company took this precautionary measure because sampling revealed Salmonella in the product. No dog illnesses have been reported.. Salmonella can affect animals eating the products and there is risk to humans from handling contaminated pet products, especially if they have not thoroughly washed their hands after having contact with the products or any surfaces exposed to these products.. People infected with Salmonella should monitor themselves for some or all of the following symptoms: nausea, vomiting, diarrhea or bloody diarrhea, abdominal cramping and fever. Rarely, Salmonella can result in more serious ailments, including arterial infections, endocarditis, arthritis, muscle pain, eye irritation, and urinary tract symptoms. Consumers exhibiting these signs after having contact with this product should contact their healthcare providers.. Pets with ...
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 ...

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 ...

The Food and Drug Administration (FDA) announced that nSpired Natural Foods is recalling a list of peanut butters due to a potential salmonella contamination. Recalled brands include Arrowhead Mills, MaraNatha, and private labels sold at Kroger, Safeway, Trader Joes, and Whole Foods.. See the complete list of 43 recalled peanut and nut butters here. The list includes unit UPCs and Best By Date ranges to watch out for. The possible contamination was discovered during a routine FDA testing and after four illnesses with possiby ties to the recall were reported. Symptoms of salmonella include fever, diarrhea (which may be bloody), nausea, vomiting, and abdominal pain. 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 ...
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
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 ...
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

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,
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 ...
