Genomic fingerprinting and development of a dendrogram for Brucella spp. isolated from seals, porpoises, and dolphins. (1/532)

Genomic DNA from reference strains and biovars of the genus Brucella was analyzed using pulsed-field gel electrophoresis (PFGE). Fingerprints were compared to estimate genetic relatedness among the strains and to obtain information on evolutionary relationships. Electrophoresis of DNA digested with the restriction endonuclease XbaI produced fragment profiles for the reference type strains that distinguished these strains to the level of species. Included in this study were strains isolated from marine mammals. The PFGE profiles from these strains were compared with those obtained from the reference strains and biovars. Isolates from dolphins had similar profiles that were distinct from profiles of Brucella isolates from seals and porpoises. Distance matrix analyses were used to produce a dendrogram. Biovars of B. abortus were clustered together in the dendrogram; similar clusters were shown for biovars of B. melitensis and for biovars of B. suis. Brucella ovis, B. canis, and B. neotomae differed from each other and from B. abortus, B. melitensis, and B. suis. The relationship between B. abortus strain RB51 and other Brucella biovars was compared because this strain has replaced B. abortus strain 19 for use as a live vaccine in cattle and possibly in bison and elk. These results support the current taxonomy of Brucella species and the designation of an additional genomic group(s) of Brucella. The PFGE analysis in conjunction with distance matrix analysis was a useful tool for calculating genetic relatedness among the Brucella species.  (+info)

Brucella outer membrane lipoproteins share antigenic determinants with bacteria of the family Rhizobiaceae. (2/532)

Brucellae have been reported to be phylogenetically related to bacteria of the family Rhizobiaceae. In the present study, we used a panel of monoclonal antibodies (MAbs) to Brucella outer membrane proteins (OMPs) to determine the presence of common OMP epitopes in some representative bacteria of this family, i.e., Ochrobactrum anthropi, Phyllobacterium rubiacearum, Rhizobium leguminosarum, and Agrobacterium tumefaciens, and also in bacteria reported to serologically cross-react with brucella, i.e., Yersinia enterocolitica O:9, Escherichia coli O:157, and Salmonella urbana. In particular, most MAbs to the Brucella outer membrane lipoproteins Omp10, Omp16, and Omp19 cross-reacted with O. anthropi and P. rubiacearum, which are actually the closest relatives of brucellae. Some of them also cross-reacted, but to a lower extent, with R. leguminosarum and A. tumefaciens. The putative Omp16 and Omp19 homologs in these bacteria showed the same apparent molecular masses as their Brucella counterparts. None of the antilipoprotein MAbs cross-reacted with Y. enterocolitica O:9, E. coli O:157, or S. urbana.  (+info)

Early acidification of phagosomes containing Brucella suis is essential for intracellular survival in murine macrophages. (3/532)

Brucella suis is a facultative intracellular pathogen of mammals, residing in macrophage vacuoles. In this work, we studied the phagosomal environment of these bacteria in order to better understand the mechanisms allowing survival and multiplication of B. suis. Intraphagosomal pH in murine J774 cells was determined by measuring the fluorescence intensity of opsonized, carboxyfluorescein-rhodamine- and Oregon Green 488-rhodamine-labeled bacteria. Compartments containing live B. suis acidified to a pH of about 4.0 to 4.5 within 60 min. Acidification of B. suis-containing phagosomes in the early phase of infection was abolished by treatment of host cells with 100 nM bafilomycin A(1), a specific inhibitor of vacuolar proton-ATPases. This neutralization at 1 h postinfection resulted in a 2- to 34-fold reduction of opsonized and nonopsonized viable intracellular bacteria at 4 and 6 h postinfection, respectively. Ammonium chloride and monensin, other pH-neutralizing reagents, led to comparable loss of intracellular viability. Addition of ammonium chloride at 7 h after the beginning of infection, however, did not affect intracellular multiplication of B. suis, in contrast to treatment at 1 h postinfection, where bacteria were completely eradicated within 48 h. Thus, we conclude that phagosomes with B. suis acidify rapidly after infection, and that this early acidification is essential for replication of the bacteria within the macrophage.  (+info)

Improved method for purification of bacterial DNA from bovine milk for detection of Brucella spp. by PCR. (4/532)

Different methods of extraction of bacterial DNA from bovine milk to improve the direct detection of Brucella by PCR were evaluated. We found that the use of a lysis buffer with high concentrations of Tris, EDTA, and NaCl, high concentrations of sodium dodecyl sulfate and proteinase K, and high temperatures of incubation was necessary for the efficient extraction of Brucella DNA. The limit of detection by PCR was 5 to 50 Brucella CFU/ml of milk.  (+info)

Outer membrane proteins Omp10, Omp16, and Omp19 of Brucella spp. are lipoproteins. (5/532)

The deduced sequences of the Omp10, Omp16, and Omp19 outer membrane proteins of Brucella spp. contain a potential bacterial lipoprotein processing sequence. After extraction with Triton X-114, these three proteins partitioned into the detergent phase. Processing of the three proteins is inhibited by globomycin, a specific inhibitor of lipoprotein signal peptidase. The three proteins were radioimmunoprecipitated from [(3)H]palmitic acid-labeled Brucella abortus lysates with monoclonal antibodies. These results demonstrate that Omp10, Omp16, and Omp19 are lipoproteins.  (+info)

Detection of antibodies to Brucella cytoplasmic proteins in the cerebrospinal fluid of patients with neurobrucellosis. (6/532)

The diagnosis of human neurobrucellosis usually relies on the detection of antibodies to Brucella lipopolysaccharide (LPS) in cerebrospinal fluid (CSF) by agglutination tests or enzyme-linked immunosorbent assay (ELISA). Here we describe the detection of immunoglobulin G (IgG) to cytoplasmic proteins (CP) of Brucella spp. by ELISA and Western blotting in seven CSF samples from five patients with neurobrucellosis. While IgG to CP (titers of 200 to 12, 800) and IgG to LPS (800 to 6,400) were found in the CSF of these patients, these antibodies were not detected in CSF samples from two patients who had systemic brucellosis without neurological involvement. The latter, however, had serum IgG and IgM to both LPS and CP. No reactivity to these antigens was found in CSF samples from 14 and 20 patients suffering from nonbrucellar meningitis and noninfectious diseases, respectively. These findings suggest that, in addition to its usefulness in the serological diagnosis of human systemic brucellosis, the ELISA with CP antigen can be used for the specific diagnosis of human neurobrucellosis.  (+info)

The 18-kDa cytoplasmic protein of Brucella species --an antigen useful for diagnosis--is a lumazine synthase. (7/532)

Previous studies have shown that the detection of antibodies to an 18-kDa cytoplasmic protein of Brucella spp. is useful for the diagnosis of human and animal brucellosis. This protein has now been expressed in recombinant form in Escherichia coli. The recombinant protein is soluble only under reducing conditions, but alkylation with iodoacetamide renders it soluble in non-reducing media. As shown by gel exclusion chromatography, this soluble form arranges in pentamers of 90 kDa. The reactivity of human and animal sera against the recombinant protein was similar to that found with the native protein present in brucella cytoplasmic fraction, suggesting that the recombinant protein is correctly folded. The protein has low but significant homology (30%) with lumazine synthases involved in bacterial riboflavin biosynthesis, which also arrange as pentamers. Biological tests on the crude extract of the recombinant bacteria and on the purified recombinant protein showed that the biological activity of the Brucella spp. 18-kDa protein is that of lumazine synthase. Preliminary crystallographic analysis showed that the Brucella spp. lumazine synthase arranges in icosahedric capsids similar to those formed by the lumazine synthases of other bacteria. The high immunogenicity of this protein, potentially useful for the design of acellular vaccines, could be explained by this polymeric arrangement.  (+info)

Competitive enzyme immunoassay for diagnosis of human brucellosis. (8/532)

The methods commonly used for human brucellosis serological testing are agglutination tests and the complement fixation test (CFT). Among the newer serological tests, primary binding assays were developed to improve sensitivity and specificity. The competitive enzyme immunoassay (CELISA) for the detection of serum antibody to Brucella is a multispecies assay which appears to be capable of differentiating vaccinal and cross-reacting antibodies from antibodies elicited by field infection in cattle. The competing monoclonal antibody used in this assay is specific for a common epitope of smooth lipopolysaccharide (S-LPS). In this study, we compared the CELISA to the classical tests for the diagnosis of human brucellosis. The CELISA cutoff value was determined to calculate its diagnostic specificity and sensitivity. A survey was performed with 911 sera. Of the sera, 341 were from an asymptomatic population that tested negative with conventional serological tests (screening and confirmatory). Based on these samples, the CELISA specificities were determined to be 99.7 and 100% with cutoff values of 28 and 30% inhibition (%I), respectively. In a further study with 393 additional sera from an asymptomatic population found negative by the conventional screening tests, the CELISA specificities were calculated to be 96.5 and 98.8% with cutoff values of 28 and 30%I. The CELISA sensitivities were determined to be 98.3 and 94.8% with cutoff values of 28 and 30%I, respectively, for sera from 116 individuals found positive by the classical tests. For the 51 culture-positive patients, CELISA was positive for 100%, the CFT was positive for 92%, and the standard tube agglutination test (TAT) was positive for 100%. The CELISA specificity was 100% for 31 sera from patients found negative by conventional serological tests but with brucellosis-like symptoms. The CELISA is fairly rapid to perform, somewhat faster than TAT, and cross-reacts less with other antigens (or antibodies) than the conventional tests. Further, the CELISA is simpler to perform that the CFT and may readily be standardized by the use of purified S-LPS antigen and monoclonal antibody for competition.  (+info)

The genus Brucella contains highly infectious species that are classified as biological threat agents. The timely detection and identification of the microorganism involved is essential for an effective response not only to biological warfare attacks but also to natural outbreaks. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) is a rapid method for the analysis of biological samples. The advantages of this method, compared to conventional techniques, are rapidity, cost-effectiveness, accuracy and suitability for the high-throughput identification of bacteria. Discrepancies between taxonomy and genetic relatedness on the species and biovar level complicate the development of detection and identification assays. In this study, the accurate identification of Brucella species using MALDI-TOF-MS was achieved by constructing a Brucella reference library based on multilocus variable-number tandem repeat analysis (MLVA) data. By comparing MS-spectra from Brucella

An anti-Brucella vaccine candidate which comprises of purified Brucella lipopolysaccharide and cocktail of four Salmonella Typhimurium (ST)-Brucella vectors was reported earlier. Each vector constitutively express highly conserved Brucella antigens (rB), viz. lumazine synthase (BLS), proline racemase subunit A (PrpA), outer membrane protein-19 (Omp19), and Cu-Zn superoxide dismutase (SOD). The present study determined relative level of protection conferred by each single strain. Upon virulent challenge, the challenge strain was recovered most abundantly in non-immunized control mice and the ST-Omp19, ST-BLS, LPS, and ST-SOD immunized mice groups showed much less burden. Indirect ELISA based assay also confirmed the induction of antigen specific IgG for each antigen delivered. In route-wise comparison of the combined vaccine candidate, intraperitoneal (IP), intramuscular (IM), and subcutaneous (SC) immunizations revealed an indication of highly efficient routes for the protection. Splenocytes of ...
The patterns of susceptibility to hydrophobic and hydrophilic drugs and the uptake of the fluorescent probe N-phenyl-naphthylamine in Brucella spp., Haemophilus influenzae, Escherichia coli, and deep rough Salmonella minnesota mutants were compared. The results show that the outer membranes of smooth and naturally rough Brucella spp. do not represent barriers to hydrophobic permeants and that this absence of a barrier relates at least in part to the properties of Brucella lipopolysaccharide. ...

Brucella species include important zoonotic pathogens that have a substantial impact on both agriculture and human health throughout the world. Brucellae are thought of as stealth pathogens that escape recognition by the host innate immune response, modulate the acquired immune response, and evade intracellular destruction. We analyzed the genome sequences of members of the family Brucellaceae to assess its evolutionary history from likely free-living soil-based progenitors into highly successful intracellular pathogens. Phylogenetic analysis split the genus into two ...

Interpretive Summary: Brucella are intracellular pathogens that cause reproductive losses in cattle and zoonotic infections in people. Live attenuated vaccines have been available for protecting domestic livestock against brucellosis for more than 60 years. Current vaccines are effective in preventing abortion and transmission of brucellosis, but poor at preventing infection or seroconversion. Current knowledge suggests that both the innate and adaptive immune responses contribute to immunity against intracellular pathogens and that binding of pathogen structures onto pattern recognition receptors (PMRs) is critical to development of protective immunity. The observations that killed bacteria or subunit vaccines do not appear to fully stimulate PMRs or mimic intracellular trafficking of live Brucella, may explain their inability to induce protection that equals that provided by live vaccines. Brucella appear to have multiple mechanisms that subvert innate and adaptive immunity and prevent or ...

When and how often laboratory tests are done may depend on many factors. The timing of laboratory tests may rely on the results or completion of other tests, procedures, or treatments. Lab tests may be performed immediately in an emergency, or tests may be delayed as a condition is treated or monitored. A test may be suggested or become necessary when certain signs or symptoms appear. Due to changes in the way your body naturally functions through the course of a day, lab tests may need to be performed at a certain time of day. If you have prepared for a test by changing your food or fluid intake, lab tests may be timed in accordance with those changes. Timing of tests may be based on increased and decreased levels of medications, drugs or other substances in the body. The age or gender of the person being tested may affect when and how often a lab test is required. Chronic or progressive conditions may need ongoing monitoring through the use of lab tests. Conditions that worsen and improve may ...

Spleen cells from mice infected with the rough Brucella melitensis strain B115 were fused with NSO myeloma cells. Hybridoma supernatants were screened in ELISA with cell walls (CW), sonicated cell extracts (CE) and rough lipopolysaccharide (R-LPS) of B. melitensis strain B115 and whole B. melitensis B115 cells. Surprisingly, 22 monoclonal antibodies (mAbs) reacting in ELISA with both CW and CE but not with R-LPS and bacterial cells were shown by immunoblot analysis and ELISA to react with smooth lipopolysaccharide (S-LPS). These mAbs also reacted in ELISA with O polysaccharides (OPS) from the smooth Brucella abortus strain 99 and the smooth B. melitensis strain 16M and thus recognize epitopes present on the O-chain. Proteinase K LPS preparations from B. melitensis B115 analysed by immunoblotting with one mAb (12G12) recognizing S-LPS of both A and M specificity displayed the typical S-LPS high-molecular-mass ladder pattern but no S-LPS was detected in the phenol/water/chloroform/light petroleum LPS
Pathogens infecting mammalian cells have developed various strategies to suppress and evade their hosts defensive mechanisms. In this line, the intracellular bacteria that are able to survive and propagate within their host cells must have developed strategies to avert their hosts killing attitude. Studying the interface of host-pathogen confrontation can provide valuable information for defining therapeutic approaches. Brucellosis, caused by the Brucella strains, is a zoonotic bacterial disease that affects thousands of humansand animals around the world inflicting discomfort and huge economic losses. Similar to many other intracellular dwelling bacteria, infections caused by Brucella are difficult to treat, and hence any attempt at identifying new and common therapeutic targets would prove beneficial for the purpose of curing infections caused by the intracellular bacteria. In THP-1 macrophage infected with Brucella melitensis we studied the expression levels of four hosts genes, i.e. EMP2, ST8SIA4

The results of various analyses (DNA fragmentation, microscopic analysis, and flow cytometry analysis) showed that Brucella infection inhibited apoptosis which spontaneously occurs in human monocytes in the absence of an activation signal and rendered macrophagic cells resistant to apoptosis induced by immunological factors.. Although the Brucella-mediated effect on monocyte apoptosis was somewhat similar to the E. coli LPS effect (references24 and 28 and our results), convergent data demonstrated that Brucella LPS cannot account for the antiapoptotic properties of the live bacteria. (i) Experiments performed in the presence of neutralizing anti-TNF-α Ab showed that TNF-α, which plays a central role in Brucella(or E. coli) LPS-induced protection of monocytes, did not participate in the ...

Brucellosis is a contagious disease of animals that also affects humans. The disease is also known as Bangs Disease. In humans, its known as Undulant Fever.. Brucellosis is one of the most serious diseases of livestock, considering the damage done by the infection in animals. Decreased milk production, weight loss, loss of young, infertility, and lameness are some of the affects on animals.. The Brucella species are named for their primary hosts: Brucella melitensis is found mostly is goats,sheep and camels, B. abortus is a pathogen of cattle, B. suis is found primarily in swine and B. canis is found in dogs.. There are two common ways people get infected with brucellosis. First, individuals that work with infected animals that have not been vaccinated against brucellosis. This would include farmers, slaughterhouse workers and veterinarians.. Related: College microbiology classes linked to Salmonella Typhimurium outbreak. They get infected through direct contact or aerosols produced by the ...
The current investigation is associated with the third known case of brucellosis from Brucella RB51 in a New York resident who who drank raw milk purchased from Millers Biodiversity Farm in Quarryville, Pennsylvania, was diagnosed with brucellosis in November 2018.. Milk samples from the dairy tested positive for Brucella strain RB51. People who consumed raw milk or raw milk products from this dairy since January 2016 may have been exposed.. As of January 22, 2019, exposures have been identified in 19 states: Alabama, California, Connecticut, Florida, Georgia, Iowa, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, and Virginia.. CDC notes that Brucella strain RB51 is a live-attenuated cattle vaccine strain, which can be shed in milk and can cause infections in humans. RB51 is resistant to rifampin and penicillin. There is no serological test available to detect RB51 infection. Blood culture is the ...

We report a case of Brucella abortus-induced brucellosis that displayed high hepatic transaminases similar to that in acute hepatitis, fourth month relapsed following doxycycline-streptomycin treatment, and developed doxycycline-related hepatotoxicity in second treatment. Brucella hepatitis may occur with various Brucella spp. and may relapse even following ...
Brucella species are small, coccobacillary, Gram-negative rods that morphologically resemble Haemophilus and Bordetella. They are nonmotile, non-acid-fast, and non-spore-forming. The cells have a typical Gram-negative structure, and the outer membrane contains proteins. The genus Brucella contains nine closely related variants that differ primarily in their preferred terrestrial or marine hosts. Taxonomists vacillate as to whether they should be called species or something else. The three most commonly infecting humans, B abortus (cattle), B melitensis (sheep, goats), and B suis (swine), will all be referred to here as Brucella abortus or simply Brucella ...
Using serology and bacterial culture, we determined the prevalence of Brucella spp. and the antibody to Brucella spp. in a feral swine (Sus scrofa) population in proximity to a cattle herd that was culture positive for Brucella abortus and Brucella suis in north-central Texas, USA. During a prospective cross-sectional quantitative study in April 2005, we collected blood and tissue samples from 40 feral swine within a 30-km radius of the infected herd. Serum samples were tested by the Rose Bengal test, particle concentration fluorescence immunoassay, and fluorescence polarization assay. In addition, tissue samples were cultured, and the Brucella species and biovar determined. Four feral swine were Brucella positive by serology, and two were culture positive for B. suis biovar 1. Of the culture-positive swine, one was concurrently antibody and culture positive, and one was culture positive only. The presumptive source of the B. suis infection in the index cattle herd was likely the surrounding feral swine
In 1999, a researcher suffered headaches, lassitude and a severe sinusitis after exposure to marine mammal strains of Brucella with which the worker was in contact. The symptoms resolved in one week after treatment with doxycycline and rifampin. The researcher had a positive titer for Brucella, and the organism was cultured from blood samples. PCR-RFLP was used to positively identify the isolates as being comparable to marine mammal Brucella (Brew and Staunton 1999). Organisms Brucella ssp. are gram-negative intracellular bacteria and are a major source of zoonoses worldwide. B. melitensus, B. abortus, and B. suis are some species commonly recognized to play a role in human and animal health. Nomenclature for marine mammal strains of Brucella has not yet been fully developed, but B. maris and B. pinnipedia have so far been named. Transmission occurs primarily through contact with aborted fetal material, and consumption of contaminated milk. ...
What is brucellosis? Brucellosis is an infectious disease caused by the bacteria of the genus Brucella. These bacteria are primarily passed among animals, and they cause disease in many different vertebrates. Various Brucella species affect sheep, goats, cattle, deer, elk, pigs, dogs, and several other animals. Humans become infected by coming in contact with animals or animal products that are contaminated with these bacteria. In humans brucellosis can cause a range of symptoms that are similar to the flu and may include fever, sweats, headaches, back pains, and physical weakness. Severe infections of the central nervous systems or lining of the heart may occur. Brucellosis can also cause long-lasting or chronic symptoms that include recurrent fevers, joint pain, and fatigue.. Back to Top How common is brucellosis? Brucellosis is not very common in the United States, where100 to 200 cases occur each year. But brucellosis can be very common in countries where animal disease control programs have ...
Brucella canis is a Gram-negative proteobacterium in the family Brucellaceae that causes brucellosis in dogs and other canids. B. canis is rod-shaped or a coccus, and is oxidase, catalase, and urease positive. The species was firstly described in United States in 1966 where mass abortions of beagles were documented. The disease is characterized by epididymitis and orchitis in male dogs, endometritis, placentitis, and abortions in females, and often presents as infertility in both sexes. Other symptoms such as inflammation in the eyes and axial and appendicular skeleton; lymphadenopathy and splenomegaly, are less common. Humans can be also infected, but occurrences are rare. B. canis is a zoonotic organism. Signs of this disease are different in both genders of dogs; females that have B. canis infections face an abortion of their developed fetuses. Males face the chance of infertility, because they develop an antibody against the sperm. This may be followed by inflammation of the testes which ...
Brucella, a Gram-negative bacterium, is classified as a potential bioterrorism agent mainly due to the low dose needed to cause infection and the ability to transmit the bacteria via aerosols. Goats/sheep, cattle, pigs, dogs, sheep and rodents are infected by B. melitensis, B. abortus, B. suis, B. canis, B. ovis and B. neotomae, respectively, the six classical Brucella species. Most human cases are caused by B. melitensis and B. abortus. Our aim was to specifically detect Brucellae with smooth lipopolysaccharide (LPS) using a highly sensitive monoclonal antibody (mAb) based immunological assay. To complement molecular detection systems for potential bioterror agents, as required by international biodefense regulations, sets of mAbs were generated by B cell hybridoma technology and used to develop immunological assays. The combination of mAbs most suitable for an antigen capture assay format was identified and an immunoassay using the Luminex xMAP technology was developed.
Neutralophilic bacteria have developed specific mechanisms to cope with the acid stress encountered in environments such as soil, fermented foods- and host compartments. In Escherichia coli, the glutamate decarboxylase (Gad)-dependent system is extremely efficient: it requires the concerted action of glutamate decarboxylase (GadA/GadB) and of the glutamate/GABA antiporter, GadC. Notably, this system is operative also in new strains/species of Brucella, among which Brucella microti, but not in the
Oceans and seas are the widest sources of biological and chemical diversity representing a prolific reserve of unexploited and/or unknown microorganisms [1, 2]. Thus, marine environments are great resources of new substances having potential applications in pharmaceutical, feed and food, fine chemicals and enzyme industries [2, 3]. The search of new microorganisms, having unique physiological and metabolic capabilities, aids to better comprehend the ecosystem and provides opportunities to discover new compounds of commercial importance. This is particularly true for marine bacteria that have been less studied than their terrestrial counterpart and are often underrated or completely ignored by many scientists [4, 5].. Among the microbial products, exopolysaccharides (EPS) have many important physiological functions and various practical applications deductible from their roles in nature.. These high molecular weight polymers represent essential components of the secreted extracellular material ...
Recent studies show that FDG-PET may contribute for precise grading and prognosis in different solid tumors, including soft tissue sarcomas [5], as high grade tumors show a much higher uptake of 18F-FDG due to a higher glycolytic phenotype [3]. Also, it was recently described that FDG-PET should be considered an important imaging modality for therapeutic monitoring in patients with high-grade STS [6, 7]. In this context, metabolic characterization of STS emerges as a possibly relevant approach for STS management, with therapeutic implications as early treatment decisions such as discontinuation of chemotherapy in non-responding patients could be based on FDG-PET criteria [7]. Importantly, the hyperglycolytic phenotype present in this type of tumors, similarly to other solid tumors, may be the basis for the use of new directed therapeutic strategies which are currently in clinical trials [29]. Therefore, tumor metabolic characterization, including MCTs as responsible for lactate efflux from ...
Brucellosis is one of the most widespread zoonosis in the world. In China, 90% of human brucellosis occurs in six northern agricultural provinces. However, there is a recent increase in the trend of human brucellosis in southern provinces with limited cases reported in the literature. Our study aims to describe the clinical features and epidemiology of brucellosis in a tertiary hospital in southern China. A retrospective case series of brucellosis was conducted between January 1, 2014 and October 31. 2018. Cases were identified based on positive Brucella serology by tube agglutination test, or positive culture from clinical specimen identified by Vitek 2 and MALDL-TOF MS. Clinical details of brucellosis including patients occupation, risk factors, and complications were analyzed. Clinical characteristics between patients from Guangdong and other provinces were also compared. A total of 13 cases of laboratory-confirmed brucellosis were identified. 7 (53.8%) of the patients were male, 6 (46.2%) were

Brucellosis is a zoonotic bacterial disease caused by Brucella spp. The virulence of these bacteria is dependent on their ability to invade and replicate within host cells. In a previous study, a putative gene bab_RS27735 encoding an amino acid ABC transporter substrate-binding protein homologous to AapJ protein was found to be involved in Brucella abortus virulence. In this study, we successfully constructed a bab_RS27735 deletion mutant, Δ27735. Compared with the wild-type strain, the lipopolysaccharide pattern of the mutant was not changed, but the growth ability was slightly defected in the exponential phase. In tolerance tests, sensitivity of the Δ27735 mutant to oxidative stress, bactericidal peptides or low pH was not different from that of the wild-type strain. Cell infection assay showed that the mutant was reduced survival within macrophages but could efficiently escape lysosome degradation. The results of a virulence test showed that the Δ27735 mutant was attenuated in a mouse model at the

Brucellosis is a common bacterial zoonotic infection but data on the prevalence among humans and animals is limited in Kenya. A cross-sectional survey was conducted in three counties practicing different livestock production systems to simultaneously assess the seroprevalence of, and risk factors for brucellosis among humans and their livestock (cattle, sheep, camels, and goats). A two-stage cluster sampling method with random selection of sublocations and households was conducted. Blood samples were collected from humans and animals and tested for Brucella immunoglobulin G (IgG) antibodies. Human and animal individual seroprevalence was 16% and 8%, respectively. Household and herd seroprevalence ranged from 5% to 73% and 6% to 68%, respectively. There was a 6-fold odds of human seropositivity in households with a seropositive animal compared with those without. Risk factors for human seropositivity included regular ingestion of raw milk (adjusted odds ratio [aOR] = 3.5, 95% confidence interval ...
Brucella abortus causes brucellosis mainly in cattle. The infection is transmitted to humans by ingestion of animal products or direct contact with infected material. While the intracellular lifestyle of Brucella is well characterized, its extracellular survival is poorly understood. In nature, bacterial persistence is associated with biofilms, where aggregated cells are protected from adversity. The inability of Brucella abortus to aggregate under aerobiosis and that fact that the replicative niche of Brucella is characterized by microaerobic conditions prompted us to investigate the capacity of this pathogen to aggregate and grow in biofilms under microaerobiotic conditions. The results show that B. abortus aggregates and produces biofilms. The aggregates tolerate desiccation better than planktonic cells do, adhere and displace even in the absence of the lipopolysaccharide-O antigen, flagella, the transcriptional regulator VjbR, or the enzymes that synthesize, transport, and modify cyclic β ...
Among animals, brucellosis is transmitted directly (contact with placenta, aborted fetus, the liquor , vaginal and/or uterus secretion) or indirectly (if infected and non-infected health herds mix while grazing or by contact with environment in which the bacteria can be found such as manure, pastures, water, etc). Most infected male animals continue to secrete Brucella via semen for the lifetime. Presence of infectious agents in udder and surrounding lymph nodes results in permanent or occasional secretion of Brucella via milk and as such it is a serious source of infection for young animals which can also be infected via uterus. In infected lambs and young goats, Brucella inhabits lymph nods of bowls and can be secreted out of their body via droppings. Infected young cattle develop the disease once they reached sexual maturity. Sheppard dogs can also spread brucellosis between ruminants but they can also get ill as well. In high humidly, low temperature and unsunny weather conditions, Brucella ...
Symptomatic seropositive family members were treated, whereas asymptomatic seropositive family members were followed-up with no treatment unless they showed symptoms and an increase in STA titers. Of eight family members followed, two were diagnosed with acute brucellosis.. Discussion. Turkey has seven geographical regions and is an important migration route between Europe and Asia. There are significant differences between regions, in terms of geographical features and economic and social development. Due to the geographic situation, Turkey is a risk factor for many infectious diseases, such as brucellosis.11 A total of 189,226 cases of human brucellosis were officially reported between 2000 and 2005, of which approximately 90,000 were registered (approximately 15,000 cases per year) in Turkey. The highest seroprevalence was observed in the eastern and southeastern regions of the country.12 Despite being endemic in Turkey, brucellosis remains underdiagnosed due to its non-specific clinical ...

Brucella spp. are zoonotic Gram-negative intracellular pathogens with the ability to survive and replicate in phagocytes. It has been shown that bacterial proteins expressed abundantly in this niche are stress-related proteins capable of triggering effective immune responses. BMEI1549 is a molecular chaperone designated DnaK that is expressed under stress conditions and helps to prevent formation of protein aggregates. In order to study the potential of DnaK as a prospective Brucella subunit vaccine, immunogenicity and protective efficacy of recombinant DnaK from Brucella melitensis was evaluated in BALB/c mice. The dnak gene was cloned, expressed in Escherichia coli, and the resulting recombinant protein used as subunit vaccine. DnaK-immunized mice showed a strong lymphocyte proliferative response to in vitro antigen stimulation. Although comparable levels of antigen-specific IgG2a and IgG1 were observed in immunized mice, high amounts of IFN-?, IL-12 and IL-6, no detectable level of IL-4 and ...

On April 23, 2011, plaintiff Christine Brucella, 77, a retiree, alleged she was walking down an aisle at Shoprite supermarket in Paramus when another shopper struck her with his shopping cart, causing her to fall. Brucella claimed she sustained a fracture to her right hip in the incident. Brucella sued Shoprite of Paramus and its buying cooperative, Wakefern Food Corporation, for negligence. She claimed the aisle was too narrow to allow her to move out of the way of the shopping cart to avoid being hit by it. Plaintiffs counsel claimed the aisle created a dangerous condition for patrons who are walking when a shopper pushing a cart suddenly appears in front them. The plaintiffs liability expert testified that the aisle needed to be 12 feet wide to assure safe passage of patrons with shopping carts. The defense argued that the aisle was the appropriate size and was not a dangerous condition. Defense counsel noted that the accident was captured on surveillance video. Counsel contended that ...

A urinary tract infection (UTI) is an infection that affects part of the urinary tract.[1] When it affects the lower urinary tract it is known as a bladder infection (cystitis) and when it affects the upper urinary tract it is known as a kidney infection (pyelonephritis).[9] Symptoms from a lower urinary tract infection include pain with urination, frequent urination, and feeling the need to urinate despite having an empty bladder.[1] Symptoms of a kidney infection include fever and flank pain usually in addition to the symptoms of a lower UTI.[9] Rarely the urine may appear bloody.[6] In the very old and the very young, symptoms may be vague or non-specific.[1][10] The most common cause of infection is Escherichia coli, though other bacteria or fungi may rarely be the cause.[2] Risk factors include female anatomy, sexual intercourse, diabetes, obesity, and family history.[2] Although sexual intercourse is a risk factor, UTIs are not classified as sexually transmitted infections (STIs).[11] ...
The word cholera is from Greek: χολέρα kholera from χολή kholē "bile". Cholera likely has its origins in the Indian subcontinent as evidenced by its prevalence in the region for centuries.[13] Early outbreaks in the Indian subcontinent are believed to have been the result of poor living conditions as well as the presence of pools of still water, both of which provide ideal conditions for cholera to thrive.[71] The disease first spread by trade routes (land and sea) to Russia in 1817, later to the rest of Europe, and from Europe to North America and the rest of the world.[13] Seven cholera pandemics have occurred in the past 200 years, with the seventh pandemic originating in Indonesia in 1961.[72] The first cholera pandemic occurred in the Bengal region of India, near Calcutta starting in 1817 through 1824. The disease dispersed from India to Southeast Asia, the Middle East, Europe, and Eastern Africa.[73] The movement of British Army and Navy ships and personnel is believed to have ...
... (TD) is a stomach and intestinal infection. TD is defined as the passage of unformed stool (one or more by some definitions, three or more by others) while traveling.[2][3] It may be accompanied by abdominal cramps, nausea, fever, and bloating.[3] Occasionally bloody diarrhea may occur.[5] Most travelers recover within four days with little or no treatment.[3] About 10% of people may have symptoms for a week.[3] Bacteria are responsible for more than half of cases.[3] The bacteria enterotoxigenic Escherichia coli (ETEC) are typically the most common except in Southeast Asia, where Campylobacter is more prominent.[2][3] About 10% to 20% of cases are due to norovirus.[3] Protozoa such as Giardia may cause longer term disease.[3] The risk is greatest in the first two weeks of travel and among young adults.[2] People affected are more often from the developed world.[2] Recommendations for prevention include eating only properly cleaned and cooked food, drinking bottled water, and ...
Protective levels of anticapsular antibodies are not achieved until 7-14 days following administration of a meningococcal vaccine, vaccination cannot prevent early onset disease in these contacts and usually is not recommended following sporadic cases of invasive meningococcal disease. Unlike developed countries, in sub-Saharan Africa and other under developed countries, entire families live in a single room of a house.[21][22] Meningococcal infection is usually introduced into a household by an asymptomatic person. Carriage then spreads through the household, reaching infants usually after one or more other household members have been infected. Disease is most likely to occur in infants and young children who lack immunity to the strain of organism circulating and who subsequently acquire carriage of an invasive strain.[23] By preventing susceptible contacts from acquiring infection by directly inhibiting colonization. Close contacts are defined as those persons who could have had intimate ...

... is a large family of Gram-negative bacteria. It was first proposed by Rahn in 1936, and now includes over 30 genera and more than 100 species. Its classification above the level of family is still a subject of debate, but one classification places it in the order Enterobacterales of the class Gammaproteobacteria in the phylum Proteobacteria.[2][3][4][5] Enterobacteriaceae includes, along with many harmless symbionts, many of the more familiar pathogens, such as Salmonella, Escherichia coli, Klebsiella, and Shigella. Other disease-causing bacteria in this family include Enterobacter and Citrobacter. Members of the Enterobacteriaceae can be trivially referred to as enterobacteria or "enteric bacteria",[6] as several members live in the intestines of animals. In fact, the etymology of the family is enterobacterium with the suffix to designate a family (aceae)-not after the genus Enterobacter (which would be "Enterobacteraceae")-and the type genus is Escherichia. ...
... are a class of gram-negative bacteria, and one of the eight classes of the phylum Proteobacteria.[1] The Betaproteobacteria are a class comprising over 75 genera and 400 species of bacteria.[2] Together, the Betaproteobacteria represent a broad variety of metabolic strategies and occupy diverse environments from obligate pathogens living within host organisms to oligotrophic groundwater ecosystems. Whilst most members of the Betaproteobacteria are heterotrophic, deriving both their carbon and electrons from organocarbon sources, some are photoheterotrophic, deriving energy from light and carbon from organocarbon sources. Other genera are autotrophic, deriving their carbon from bicarbonate or carbon dioxide and their electrons from reduced inorganic ions such as nitrite, ammonium, thiosulfate or sulfide [1] - many of these chemolithoautotrophic Betaproteobacteria are economically important, with roles in maintaining soil pH and in elementary cycling. Other economically ...

Toxoplasmosis is becoming a global health hazard as it infects 30-50% of the world human population. Clinically, the life-long presence of the parasite in tissues of a majority of infected individuals is usually considered asymptomatic. However, a number of studies show that this 'asymptomatic infection' may also lead to development of other human pathologies. ...

... [1], previously known as Enterobacter aerogenes, is a Gram-negative, oxidase negative, catalase positive, citrate positive, indole negative, rod-shaped bacterium.[2] The bacterium is approximately 1-3 microns in length, and is capable of motility via peritrichous flagella.[3] K. aerogenes is a nosocomial and pathogenic bacterium that causes opportunistic infections including most types of infections. The majority are sensitive to most antibiotics designed for this bacteria class, but this is complicated by their inducible resistance mechanisms, particularly lactamase, which means that they quickly become resistant to standard antibiotics during treatment, requiring a change in antibiotic to avoid worsening of the sepsis.

... , also known simply as typhoid, is a bacterial infection due to Salmonella typhi that causes symptoms.[3] Symptoms may vary from mild to severe and usually begin six to thirty days after exposure.[1][2] Often there is a gradual onset of a high fever over several days.[1] Weakness, abdominal pain, constipation, and headaches also commonly occur.[2][6] Diarrhea is uncommon and vomiting is not usually severe.[6] Some people develop a skin rash with rose colored spots.[2] In severe cases there may be confusion.[6] Without treatment, symptoms may last weeks or months.[2] Other people may carry the bacterium without being affected; however, they are still able to spread the disease to others.[4] Typhoid fever is a type of enteric fever along with paratyphoid fever.[3]. The cause is the bacterium Salmonella typhi, also known as Salmonella enterica serotype Typhi, growing in the intestines and blood.[2][6] Typhoid is spread by eating or drinking food or water contaminated with the feces of ...
Traditionally, gonorrhea was diagnosed with Gram stain and culture; however, newer polymerase chain reaction (PCR)-based testing methods are becoming more common.[16][28] In those failing initial treatment, culture should be done to determine sensitivity to antibiotics.[29] Tests that use polymerase chain reaction (PCR, aka nucleic acid amplification) to identify genes unique to N. gonorrhoeae are recommended for screening and diagnosis of gonorrhea infection. These PCR-based tests require a sample of urine, urethral swabs, or cervical/vaginal swabs. Culture (growing colonies of bacteria in order to isolate and identify them) and Gram-stain (staining of bacterial cell walls to reveal morphology) can also be used to detect the presence of N. gonorrhoeae in all specimen types except urine.[30][31] If Gram-negative, oxidase-positive diplococci are visualized on direct Gram stain of urethral pus (male genital infection), no further testing is needed to establish the diagnosis of gonorrhea ...
... (PUD) is a break in the inner lining of the stomach, the first part of the small intestine, or sometimes the lower esophagus.[1][7] An ulcer in the stomach is called a gastric ulcer, while one in the first part of the intestines is a duodenal ulcer.[1] The most common symptoms of a duodenal ulcer are waking at night with upper abdominal pain and upper abdominal pain that improves with eating.[1] With a gastric ulcer, the pain may worsen with eating.[8] The pain is often described as a burning or dull ache.[1] Other symptoms include belching, vomiting, weight loss, or poor appetite.[1] About a third of older people have no symptoms.[1] Complications may include bleeding, perforation, and blockage of the stomach.[2] Bleeding occurs in as many as 15% of cases.[2] Common causes include the bacteria Helicobacter pylori and non-steroidal anti-inflammatory drugs (NSAIDs).[1] Other, less common causes include tobacco smoking, stress due to serious illness, Behcet disease, ...
With a fatality risk approaching 15% within 12 hours of infection, it is crucial to initiate testing as quickly as possible, but not to wait for the results before initiating antibiotic therapy. A small amount of cerebrospinal fluid (CSF) is sent to the laboratory as soon as possible for analysis. The diagnosis is suspected, when Gram-negative diplococci are seen on Gram stain of a centrifuged sample of CSF; sometimes they are located inside white blood cells. The microscopic identification takes around 1-2 hours after specimen arrival in the laboratory.[3] The gold standard of diagnosis is microbiological isolation of N. meningitidis by growth from a sterile body fluid, which could be CSF or blood.[5] Diagnosis is confirmed when the organism has grown, most often on a chocolate agar plate, but also on Thayer-Martin agar. To differentiate any bacterial growth from other species a small amount of a bacterial colony is tested for oxidase, catalase for which all clinically relevant Neisseria show a ...
Plague has a long history as a biological weapon. Historical accounts from ancient China and medieval Europe detail the use of infected animal carcasses, such as cows or horses, and human carcasses, by the Xiongnu/Huns, Mongols, Turks and other groups, to contaminate enemy water supplies. Han Dynasty General Huo Qubing is recorded to have died of such a contamination while engaging in warfare against the Xiongnu. Plague victims were also reported to have been tossed by catapult into cities under siege. In 1347, the Genoese possession of Caffa, a great trade emporium on the Crimean peninsula, came under siege by an army of Mongol warriors of the Golden Horde under the command of Janibeg. After a protracted siege during which the Mongol army was reportedly withering from the disease, they decided to use the infected corpses as a biological weapon. The corpses were catapulted over the city walls, infecting the inhabitants. This event might have led to the transfer of the plague (Black Death) via ...
... , also known simply as paratyphoid, is a bacterial infection caused by one of the three types of Salmonella enterica.[1] Symptoms usually begin 6-30 days after exposure and are the same as those of typhoid fever.[1][3] Often, a gradual onset of a high fever occurs over several days.[1] Weakness, loss of appetite, and headaches also commonly occur.[1] Some people develop a skin rash with rose-colored spots.[2] Without treatment, symptoms may last weeks or months.[1] Other people may carry the bacteria without being affected; however, they are still able to spread the disease to others.[3] Both typhoid and paratyphoid are of similar severity.[3] Paratyphoid and typhoid fever are types of enteric fever.[7] Paratyphoid is caused by the bacterium Salmonella enterica of the serotypes Paratyphi A, Paratyphi B, or Paratyphi C growing in the intestines and blood.[1] They are usually spread by eating or drinking food or water contaminated with the feces of an infected person.[1] They may ...
