Performance of competitive and indirect enzyme-linked immunosorbent assays, gel immunoprecipitation with native hapten polysaccharide, and standard serological tests in diagnosis of sheep brucellosis. (1/314)

Competitive and standard enzyme-linked immunosorbent assays (ELISAs), rose bengal (RB), complement fixation, and agar gel immunoprecipitation with native hapten (AGID-NH) were compared by using sera from Brucella-free, Brucella melitensis-infected, and B. melitensis Rev1-vaccinated sheep. The most sensitive tests were indirect ELISA and RB, and the most specific tests were AGID-NH and competitive ELISA. We show that RB followed by AGID-NH is a simple and effective system for diagnosing sheep brucellosis.  (+info)

In vitro activities of antibiotics alone and in combination against Brucella melitensis at neutral and acidic pHs. (2/314)

Brucellae survive acidic pHs in phagolysosomes. Azithromycin, streptomycin, and quinolones were active against Brucella melitensis at pH 7.0 but not at pH 5.0; rifampin and doxycycline retained activity at pH 5.0. Regardless of pH, azithromycin-rifampin and ofloxacin-rifampin showed less synergy than established streptomycin-doxycycline and rifampin-doxycycline combinations.  (+info)

Effect of early antibiotic treatment on the antibody response to cytoplasmic proteins of Brucella melitensis in mice. (3/314)

To test whether antibiotic therapy hampers the antibody response to Brucella antigens, 30 BALB/c mice were infected with Brucella melitensis H38 and randomized for treatment with doxycycline administered intraperitoneally for 42 days starting at 7 or 28 days postinfection (p.i.) (groups DOX7 and DOX28, respectively) or for no treatment (control group). Antibodies to smooth lipopolysaccharide (LPS) reached peak levels (mean optical density [OD] = 2.618) between days 56 and 70 p.i. in the control group, and similar peak levels (mean OD = 2.486) were observed in the DOX28 group, but significantly lower peak levels (mean OD = 0.821) were observed at 28 days p.i. in the DOX7 group. The antibody response against cytoplasmic proteins depleted of LPS (CPs) reached maximal levels (mean OD = 2.402) between days 56 and 70 p.i. in the control group, but no response was detected in the DOX7 group. Anti-CP antibodies were detected in only three animals from the DOX28 group, at levels significantly lower than those in the control group (mean maximal OD = 0.791). The pattern of antibody response to an 18-kDa cytoplasmic protein of Brucella spp. was similar to that against the CP antigen. This study shows that early antibiotic treatment affects the antibody response of mice to cytoplasmic proteins of Brucella and, to a lesser extent, to LPS.  (+info)

Molecular characterization of a Brucella species large DNA fragment deleted in Brucella abortus strains: evidence for a locus involved in the synthesis of a polysaccharide. (4/314)

A Brucella melitensis 16M DNA fragment of 17,119 bp, which contains a large region deleted in B. abortus strains and DNA flanking one side of the deletion, has been characterized. In addition to the previously identified omp31 gene, 14 hypothetical genes have been identified in the B. melitensis fragment, most of them showing homology to genes involved in the synthesis of a polysaccharide. Considering that 10 of the 15 genes are missing in B. abortus and that all the polysaccharides described in the Brucella genus (lipopolysaccharide, native hapten, and polysaccharide B) have been detected in all the species, it seems likely that the genes described here might be part of a cluster for the synthesis of a novel Brucella polysaccharide. Several polysaccharides have been identified as important virulence factors, and the discovery of a novel polysaccharide in the brucellae which is probably not synthesized in B. abortus might be interesting for a better understanding of the pathogenicity and host preference differences observed between the Brucella species. However, the possibility that the genes described in this paper no longer encode the synthesis of a polysaccharide cannot be excluded. Brucellae belong to the alpha-2 subdivision of the class Proteobacteria, which includes other microorganisms living in association with eucaryotic cells, some of them synthesizing extracellular polysaccharides involved in the interaction with the host cell. The genes described in this paper might be a remnant of the common ancestor of the alpha-2 subdivision of the class Proteobacteria, and the brucellae might have lost such extracellular polysaccharide during evolution if it was not necessary for survival or for establishment of the infectious process. Nevertheless, further studies are necessary to identify the entire DNA fragment missing in B. abortus strains and to elucidate the mechanism responsible for such deletion, since only 9,948 bp of the deletion was present in the sequenced B. melitensis DNA fragment.  (+info)

Identification of an IS711 element interrupting the wboA gene of Brucella abortus vaccine strain RB51 and a PCR assay to distinguish strain RB51 from other Brucella species and strains. (5/314)

Brucella abortus vaccine strain RB51 is a natural stable attenuated rough mutant derived from the virulent strain 2308. The genetic mutations that are responsible for the roughness and the attenuation of strain RB51 have not been identified until now. Also, except for an assay based on pulsed-field gel electrophoresis, no other simple method to differentiate strain RB51 from its parent strain 2308 is available. In the present study, we demonstrate that the wboA gene encoding a glycosyltransferase, an enzyme essential for the synthesis of O antigen, is disrupted by an IS711 element in B. abortus vaccine strain RB51. Exploiting this feature, we developed a PCR assay that distinguishes strain RB51 from all other Brucella species and strains tested.  (+info)

Protection of mice against brucellosis by vaccination with Brucella melitensis WR201(16MDeltapurEK). (6/314)

Human brucellosis can be acquired from infected animal tissues by ingestion, inhalation, or contamination of the conjunctiva or traumatized skin by infected animal products. A vaccine to protect humans from occupational exposure or from zoonotic infection in areas where the disease is endemic would reduce an important cause of morbidity worldwide. Vaccines currently used in animals are unsuitable for human use. We tested a live, attenuated, purine-auxotrophic mutant strain of Brucella melitensis, WR201, for its ability to elicit cellular and humoral immune responses and to protect mice against intranasal challenge with B. melitensis 16M. Mice inoculated intraperitoneally with WR201 made serum antibody to lipopolysaccharide and non-O-polysaccharide antigens. Splenocytes from immunized animals released interleukin-2 (IL-2), gamma interferon, and IL-10 when cultured with Brucella antigens. Immunization led to protection from disseminated infection but had only a slight effect on clearance of the challenge inoculum from the lungs. These studies suggest that WR201 should be further investigated as a vaccine to prevent human brucellosis.  (+info)

Brucellar spondylitis: review of 35 cases and literature survey. (7/314)

Thirty-five patients aged 14-74 years (average, 54 years) who had brucellar spondylitis were treated between January 1991 and December 1997. The time from onset of symptoms to diagnosis of spondylitis ranged from 1 week to 8 months (median, 9 weeks). Back or neck pain (100% of patients), fever (66%), and constitutional symptoms (57%) were the most common symptoms. Cultures of blood specimens from 26 patients (74%) were positive for Brucella melitensis. The duration of antimicrobial therapy (median, 120 days; range, 45-535 days) varied according to clinical response and the presence of epidural and paravertebral masses. One of the 35 patients underwent surgical treatment of a spinal epidural abscess. Therapy failed for 9 patients (26%; 95% confidence interval [CI], 12%-43%), and 5 (14%; 95% CI, 5%-30%) had a relapse. There were no deaths or severe sequelae in this study. Brucellar spondylitis causes considerable suffering and absenteeism from work, but long-term clinical responses are favorable.  (+info)

Effects of opsonization and gamma interferon on growth of Brucella melitensis 16M in mouse peritoneal macrophages in vitro. (8/314)

Entry of opsonized pathogens into phagocytes may benefit or, paradoxically, harm the host. Opsonization may trigger antimicrobial mechanisms such as reactive oxygen or nitric oxide (NO) production but may also provide a safe haven for intracellular replication. Brucellae are natural intramacrophage pathogens of rodents, ruminants, dogs, marine mammals, and humans. We evaluated the role of opsonins in Brucella-macrophage interactions by challenging cultured murine peritoneal macrophages with Brucella melitensis 16M treated with complement- and/or antibody-rich serum. Mouse serum rich in antibody against Brucella lipopolysaccharide (LPS) (aLPS) and human complement-rich serum (HCS) each enhanced the macrophage uptake of brucellae. Combinations of suboptimal levels of aLPS (0. 01%) and HCS (2%) synergistically enhanced uptake. The intracellular fate of ingested bacteria was evaluated with an optimal concentration of gentamicin (2 microg/ml) to control extracellular growth but not kill intracellular bacteria. Bacteria opsonized with aLPS and/or HCS grew equally well inside macrophages in the absence of gamma interferon (IFN-gamma). Macrophage activation with IFN-gamma inhibited replication of both opsonized and nonopsonized brucellae but was less effective in inhibiting replication of nonopsonized bacteria. IFN-gamma treatment of macrophages with opsonized or nonopsonized bacteria enhanced NO production, which was blocked by N(G)-monomethyl L-arginine (MMLA), an NO synthesis inhibitor. MMLA also partially blocked IFN-gamma-mediated bacterial growth inhibition. These studies suggest that primary murine macrophages have limited ability to control infection with B. melitensis, even when activated by IFN-gamma in the presence of highly opsonic concentrations of antibody and complement. Additional cellular immune responses, e.g., those mediated by cytotoxic T cells, may play more important roles in the control of murine brucellosis.  (+info)

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
A case of Brucella melitensis endocarditis in a patient with cardiovascular implantable electronic device Wasl Al-Adsani, Ali Ahmad, Mohammad Al-Mousa Department of Internal Medicine, Mubarak Al-Kabeer Hospital, Jabriya, Kuwait Background: Brucellosis is a bacterial infection, caused by the nonmotile gram-negative aerobic coccobacilli. The clinical manifestation of brucellosis is variable, ranging from mild disease to severe disease. The gold standard test to confirm the diagnosis of brucellosis is assaying blood, bone marrow, or other body fluids or by tissue culture. Preferred first-line treatment in adults with uncomplicated, nonlocalized disease consists of doxycycline–aminoglycoside combination. The recommended duration of treatment is 6 weeks. Cardiovascular implantable electronic device (CIED) infection caused by brucellosis is rare and has been reported in a few case study series. We report a case of Brucella melitensis infection of CIED where, contrary to most authorities
Brucella melitensis bacteria cause persistent, intracellular infections in small ruminants as well as in humans, leading to significant morbidity and economic loss worldwide. The majority of experiments on the transcriptional responses of Brucella to conditions inside the host have been performed following invasion of cultured mammalian cells, and do not address gene expression patterns during long-term infection. Here, we examine the application of the previously developed coincidence cloning methodology to recover and characterize B. melitensis RNA from the supramammary lymph node of experimentally-infected goats. Using coincidence cloning, we successfully recovered Brucella RNA from supramammary lymph nodes of B. melitensis-infected goats at both short-term (4 weeks) and long-term (38 weeks) infection time points. Amplified nucleic acid levels were sufficient for analysis of Brucella gene expression patterns by RNA-sequencing, providing evidence of metabolic activity in both the short-term and the
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

Our aim in presenting the case is to remind the infective endocarditis which is due to this factor in the regions like our country which is endemic for ...
Brucella spp. are the etiological agents of brucellosis, a zoonotic infectious disease that causes abortion in animals and chronic debilitating illness in humans. Natural Brucella infections occur primarily through an incompletely defined mechanism of adhesion to and penetration of mucosal epithelium. In this study, we characterized changes in genome-wide transcript abundance of the most and the least invasive growth phases of B. melitensis cultures to HeLa cells, as a preliminary approach for identifying candidate pathogen genes involved in invasion of epithelial cells. B. melitensis at the late logarithmic phase of growth are more invasive to HeLa cells than mid-logarithmic or stationary growth phases. Microarray analysis of B. melitensis gene expression identified 414 up- and 40 down-regulated genes in late-log growth phase (the most invasive culture) compared to the stationary growth phase (the least invasive culture). As expected, the majority of up-regulated genes in late-log phase cultures were
Mapping the restriction fragments of the Brucella melitensis 16M genome with a new restriction endonuclease, PacI, which cut the DNA into only eight fragments, indicated that this species contains two unique and independent replicons of about 2,100 and 1,150 kb. Pulsed-field gel electrophoresis of intact DNA revealed two bands migrating the expected distances. These replicons were identified as two unique and independent chromosomes by the presence of rRNA operons and genes for heat shock proteins mapping to separate replicons. ...
Random gene inactivation used to identify cellular functions associated with virulence and survival of Brucella spp has relied heavily upon the use of the transposon Tn5 that integrates at G/C base pairs. Transposons of the mariner family do not require species-specific host factors for efficient transposition, integrate nonspecifically at T/A base pairs, and, at a minimum, provide an alternative approach for gene discovery. In this study, plasmid vector pSC189, containing both the hyperactive transposase C9 and transposon terminal inverted repeats flanking a kanamycin resistance gene, were used to deliver Himar1 transposable element into the B. melitensis genome. Conjugation was performed efficiently and rapidly in less than one generation in order to minimize the formation of siblings while assuring the highest level of genome coverage. Although previously identified groups or classes of genes required for virulence and survival were represented in the screen, additional novel identifications were
Brucellae grow and replicate in the phagolysosomes of macrophages, where the pH is 5.0 (8). Antimicrobials that penetrate this compartment and act under acidic conditions might be used as monotherapy. Only doxycycline and rifampin met these criteria, and neither is effective as monotherapy for brucellosis (9, 13). The fluoroquinolones and azithromycin had good activity at pH 7.0 but not at pH 5.0. Garcia-Rodriguez et al. (7) also found that the activity of fluoroquinolones against brucellae was two to fourfold lower at pH 5.0 than at pH 7.0. These data are supported by results of animal and clinical studies: azithromycin was less effective than doxycycline alone or with streptomycin for experimental brucellosis in mice (6), and Al-Sibai et al. (3) reported a 25% relapse rate with oral ciprofloxacin given for 6 to 8 weeks. We obtained somewhat better clinical results with oral ofloxacin, but the relapse rate was still 15% after 4 weeks (1). No relationship between in vitro susceptibility and ...

Designing a potent recombinant vaccine, using the appropriate subunits with the greatest effect on stimulating the immune system, especially in the case of intracellular pathogens such as gram negative Brucella Melitensis bacteria, is of great importance. In this study, three repeats of 27 amino acids of the immunogenic epitope derived from OMP31 antigen (3E) from the Brucella melitensis, in a protective manner against Brucellosis have been used. To fortify the delivery system of recombinant antigens, IL-2 cytokine as a molecular adjuvant was fused to recombinant constructs. Recombinant proteins were evaluated for immunological studies in a mouse model (BALB/c). The results showed that all recombinant proteins could stimulate the immune system to produce Th1 cytokines and antibodies in compare to the negative control treatments. 3E-IL2 and then OMP31-IL2 proteins stimulated higher levels of IFN-γ and IL-2 compared to the other treatments (p | 0.05). Also, the results indicated that experimental

Sulfur is an essential element for life and the metabolism of organic sulfur compounds plays an important role in the global sulfur cycle. Sulfur occurs in various oxidation states ranging from +6 in sulfate to -2 in sulfide (H2S). Sulfate reduction can occur in both an energy consuming assimilatory pathway and an energy producing dissimilatory pathway. The assimilatory pathway, which is found in a wide range of organisms, produces reduced sulfur compounds for the biosynthesis of S-containing amino acids and does not lead to direct excretion of sulfide. In the dissimilatory pathway, which is restricted to obligatory anaerobic bacterial and archaeal lineages, sulfate (or sulfur) is the terminal electron acceptor of the respiratory chain producing large quantities of inorganic sulfide. Both pathways start from the activation of sulfate by reaction with ATP to form adenylyl sulfate (APS). In the assimilatory pathway [MD:M00176] APS is converted to 3-phosphoadenylyl sulfate (PAPS) and then reduced ...

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 ...

There are four species of the Gram-negative, aerobic brucella bacillus, each comprising several biovars: Brucella melitensis (Malta fever, most commonly associated with goats, sheep, and camels), B. abortus (cattle), B. suis (pigs), and B. canis (dogs). The disease that they cause-brucellosis-occurs worldwide, but is especially prevalent in the Mediterranean region, the Indian subcontinent, Mexico, and Central and South America. Transmission is commonly by ingestion of untreated dairy products or other contaminated foods, but can also be by inhalation or inoculation....

Onze cas de brucellose ont été identifiés dans deux municipalités de Cordoba (Andalousie, Espagne). Une étude cas-témoins a été menée en prenant trois cas pour un témoin. Les cas avaient consommé du fromage non pasteurisé produit dans une ferme située dans la zone épidémique et présentaient un risque plus élevé de contracter la brucellose que les témoins ( OR = 21.6, IC95% = 1.6-639.8). Brucella melitensis serovar 3 a été identifié dans des prélèvements cliniques, des tissus de chèvre et des échantillons de lait provenant du troupeau de la ferme. Des mesures préventives ont été mises en place et l'épidémie s'est terminé après que tous les fromages suspects aient été retirés du marché. Des mesures d'hygiène plus importantes ont été instaurées à la ferme, ainsi que des actions de promotion de la santé.
En tres municipios de Córdoba (Andalucía, España) se identificaron once casos de brucelosis. Se realizó un estudio de casos y controles, seleccionando tres casos por cada control. Las personas que consumieron queso de cabra fresco sin higienizar elaborado en una granja situada en el territorio epidémico, presentaban un mayor riesgo de padecer brucelosis (OR=21,6, IC 95%=1,6-639,8). Se identificó Brucella melitensis serotipo 3 en muestras clínicas, y en tejido de cabras y muestras de leche de la granja del rebaño. Se adoptaron medidas preventivas y el brote fue contenido tras la retirada del mercado de todos los quesos sospechosos, la desinfección y limpieza adicional de la granja y la realización de actividades de promoción sanitaria.
Although not all of the differentiating genes identified were transcribed under steady state conditions, a group of genes sufficient to discriminate unambiguously between B. suis, B. melitensis, and B. abortus was identified. We present an overview of these genomic differences and the use of these f …

Leishmania major parasites reside and multiply in late endosomal compartments of host phagocytic cells. Immune control of Leishmania growth absolutely requires expression of inducible Nitric Oxide Synthase (iNOS/NOS2) and subsequent production of NO. Here, we show that CD11b+ CD11c+ Ly-6C+ MHC-II+ cells are the main iNOS-producing cells in the footpad lesion and in the draining lymph node of Leishmania major-infected C57BL/6 mice. These cells are phenotypically similar to iNOS-producing inflammatory DC (iNOS-DC) observed in the mouse models of Listeria monocytogenes and Brucella melitensis infection. The use of DsRed-expressing parasites demonstrated that these iNOS-producing cells are the major infected population in the lesions and the draining lymph nodes. Analysis of various genetically deficient mouse strains revealed the requirement of CCR2 expression for the recruitment of iNOS-DC in the draining lymph nodes, whereas their activation is strongly dependent on CD40, IL-12, IFN-gamma and ...
March 24, 2004. Goat milk sold in the United States may soon be better protected against brucellosis-causing bacteria, thanks to recent research conducted by two U.S. Department of Agriculture agencies in Ames, Iowa. A test for detecting the bacteria Brucella melitensis in bulk goat milk has been developed by research chemist Louisa Tabatabai of the Agricultural Research Services National Animal Disease Center (NADC), Barbara Martin of the Animal and Plant Health Inspection Services (APHIS) National Veterinary Services Laboratories, and graduate student Nathan Funk of Iowa State University. The test relies on an adaptation of an enzyme-linked immunoassay (ELISA) that Tabatabai helped develop in 1984 for testing cattle for B. abortus.. B. melitensis, one of six known species of Brucella bacteria that induce abortions in animals, mainly infects sheep and goats. In humans, B. melitensis infection causes Malta fever, which is characterized by fever and headaches.. Few cases of this infection in ...
Biotin (vitamin H or vitamin B7) is the essential cofactor of biotin-dependent carboxylases, such as pyruvate carboxylase and acetyl-CoA carboxylase. Mammals cannot synthesize biotin, while in bacteria, fungi, and plants it is synthesized from pimelate thioester through different pathways. In E. coli and many organisms, pimelate thioester is derived from malonyl-ACP. The pathway starts with the methylation to malonyl-ACP methyl ester, followed by the fatty acid chain elongation cycle to form pimeloyl-ACP methyl ester, which is then demethylated to form pimeloyl-ACP [MD:M00572]. Pimeloyl-ACP is converted to biotin through the final four steps in the biotin bicyclic ring assembly, which are conserved among biotin-producing organisms [MD:M00123]. In B. subtilis, biotin is derived from pimeloyl-ACP formed by oxidative cleavage of long-chain acyl-ACPs [MD:M00573]. Some bacteria synthesize biotin from pimeloyl-CoA derived from pimelate [MD:M00577]. Biotin is covalently attached to biotin-dependent ...
Brucellosis is a world-wide zoonotic disease with a major impact on the public health. Due to the high risk of laboratory acquired infection, limited laboratory investigations were performed on this organism, including detailed identification and susceptibility study. |i|Brucella melitensis|/i| is the commonest aetiological agent for human brucellosis in this region. The in vitro susceptibility pattern against selected antimicrobial agents was assessed using |i|E|/i|-test. All isolates were noted to be sensitive to all the antimicrobial agents tested except for rifampicin where elevated MIC > 1 |i|μ|/i|g/mL was noted in 30 out of 41 isolates tested.
Martinez said there have been five confirmed cases to date; however, he expects that number to climb.. Those infected are over the age of 20. The outbreak is linked to contaminated cheese..

Brucellosis generally presents with fever, malaise, weight loss and bone pain with either an abrupt or insidious onset. A 76-year-old man presented in April 2010 with fever of 103°F, severe tachycardia, tachypnoea and a blood pressure of 80/50 mm Hg requiring fluids and vasopressor support with norepinephrine. The patient had brucellosis in 1956 which was treated for many weeks with tetracycline and streptomycin. He has had no recurrences since that time. He denies recent travel outside the USA or consumption of raw dairy products. Blood cultures grew Brucella melitensis. He was treated with gentamycin, doxycycline and rifampin for 1 week and discharged home on doxycycline and rifampin. He relapsed after 2 days, requiring re-admission and a 4-week course of gentamycin. This case is most unusual in that the brucellosis presented with septic shock after a 50-year quiescence and required prolonged therapy with gentamycin to induce remission. ...
BRUCELLOSIS (Bangs Disease or Undulant fever in Humans) - Brucellosis in goats and sheep is a very serious disease caused by Brucella melitensis. Bangs disease causes spontaneous abortion in cattle and other bovines and related species, and is caused by B. abortus. In cattle, the disease is transmitted venereally and humans become infected by contacting…
The serological diagnosis of infectious diseases characterized by persistent fever is based on the agglutination reaction which undergoes between the antigen and specific antibodies which may be present in the patients serum.. The Widal reaction allows the diagnosis of infections caused by Salmonella typhi, Salmonella paratyphi Groups A, B and C.. The method has been further developed through the adoption of the somatic O and flagellar H antigens.. The Wright reaction allows the diagnosis of Brucellosis (Maltese or Mediterranean Fever) caused by 3 strains di Brucella (melitensis, abortus and suis).. The Weil-Felix reaction allows the diagnosis of Rickettsiosis and is based on the fact that three strains of Proteus (OX19, OX2 and OXK), which share somatic antigenic components with Rickettsia, are agglutinated by antibodies present in the serum of infected patients.. Listeria plus is a tube agglutination assay for titration of antibodies against Listeria.. ...

We report two laboratory-acquired Brucella melitensis infections that were shown to be epidemiologically related. Blood culture isolates were initially misidentified because of variable Gram stain results, which led to misdiagnoses and subsequent laboratory exposures. Notifying laboratory personnel who unknowingly processed cultures from brucellosis patients is an important preventive measure.

Between 1996 and 1998, a total of 2,494 samples of blood from humans and animals were collected and tested for brucellosis. This total included 1,594 samples of animal blood, collected from 1,050 sheep from 20 flocks, and 544 goats from eight herds. The serum samples were tested using the Rose Bengal test, the tube agglutination test, the complement fixation test and an enzyme-linked immunosorbent assay. Moreover, a complete history was compiled from each flock/herd. The rate of abortions in sheep due to brucellosis ranged from 0.5% to 56%, with a mean of 33.2%. The goats had a higher abortion rate. Thirty-four aborted sheep foetuses collected from these 20 flocks were bacteriologically and pathologically examined. A pure culture of Brucella melitensis biotype 3 was isolated from 21 of the aborted foetuses.. ...
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. ...
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 ...

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 ...
