A bacterial vaccine for the prevention of brucellosis in man and animal. Brucella abortus vaccine is used for the immunization of cattle, sheep, and goats.
A genus of gram-negative, aerobic bacteria that causes BRUCELLOSIS. Its cells are nonmotile coccobacilli and are animal parasites and pathogens. The bacterium is transmissible to humans through contact with infected dairy products or tissue.
Infection caused by bacteria of the genus BRUCELLA mainly involving the MONONUCLEAR PHAGOCYTE SYSTEM. This condition is characterized by fever, weakness, malaise, and weight loss.
A species of the genus BRUCELLA whose natural hosts are cattle and other bovidae. Abortion and placentitis are frequently produced in the pregnant animal. Other mammals, including humans, may be infected.
A species of the genus BRUCELLA whose natural hosts are sheep and goats. Other mammals, including humans, may be infected. In general, these organisms tend to be more virulent for laboratory animals than BRUCELLA ABORTUS and may cause fatal infections.
Suspensions of killed or attenuated microorganisms (bacteria, viruses, fungi, protozoa), antigenic proteins, synthetic constructs, or other bio-molecular derivatives, administered for the prevention, amelioration, or treatment of infectious and other diseases.
Vaccines in which the infectious microbial nucleic acid components have been destroyed by chemical or physical treatment (e.g., formalin, beta-propiolactone, gamma radiation) without affecting the antigenicity or immunogenicity of the viral coat or bacterial outer membrane proteins.
Suspensions of attenuated or killed viruses administered for the prevention or treatment of infectious viral disease.
A species of the genus BRUCELLA which are pathogenic to SHEEP.
Suspensions of attenuated or killed bacteria administered for the prevention or treatment of infectious bacterial disease.
Recombinant DNA vectors encoding antigens administered for the prevention or treatment of disease. The host cells take up the DNA, express the antigen, and present it to the immune system in a manner similar to that which would occur during natural infection. This induces humoral and cellular immune responses against the encoded antigens. The vector is called naked DNA because there is no need for complex formulations or delivery agents; the plasmid is injected in saline or other buffers.
Small synthetic peptides that mimic surface antigens of pathogens and are immunogenic, or vaccines manufactured with the aid of recombinant DNA techniques. The latter vaccines may also be whole viruses whose nucleic acids have been modified.

Vaccines or candidate vaccines containing inactivated HIV or some of its component antigens and designed to prevent or treat AIDS. Some vaccines containing antigens are recombinantly produced.
A disease of cattle caused by bacteria of the genus BRUCELLA leading to abortion in late pregnancy. BRUCELLA ABORTUS is the primary infective agent.
Vaccines consisting of one or more antigens that stimulate a strong immune response. They are purified from microorganisms or produced by recombinant DNA techniques, or they can be chemically synthesized peptides.
Semisynthetic vaccines consisting of polysaccharide antigens from microorganisms attached to protein carrier molecules. The carrier protein is recognized by macrophages and T-cells thus enhancing immunity. Conjugate vaccines induce antibody formation in people not responsive to polysaccharide alone, induce higher levels of antibody, and show a booster response on repeated injection.
Administration of vaccines to stimulate the host's immune response. This includes any preparation intended for active immunological prophylaxis.
Vaccines made from antigens arising from any of the four strains of Plasmodium which cause malaria in humans, or from P. berghei which causes malaria in rodents.
Vaccines or candidate vaccines used to prevent PAPILLOMAVIRUS INFECTIONS. Human vaccines are intended to reduce the incidence of UTERINE CERVICAL NEOPLASMS, so they are sometimes considered a type of CANCER VACCINES. They are often composed of CAPSID PROTEINS, especially L1 protein, from various types of ALPHAPAPILLOMAVIRUS.

Immunity to Brucella in mice vaccinated with a fraction (F8) or a killed vaccine (H38) with or without adjuvant. Level and duration of immunity in relation to dose of vaccine, recall injection and age of mice. (1/138)

Immunity to Brucella in the mouse, assessed by bacterial spleen counts 15 days after intraperitoneal inoculation of a standard challenge of B. abortus 544, has been studied with two vaccines, one experimental, composed of a fraction of the bacterial cell-wall (F8) extracted from B. abortus 99, the other of killed whole bacteria, B. melitensis 53 H38, taken as reference (H38). The level of primary immunity depended on the dose of vaccine, the presence of oil adjuvant and the age of the mouse. The presence of adjuvant enabled the immunization to F8 to continue beyond the first month, to reach its maximum around the fourth month, and to remain stable for at least 7 months. A booster injection 3 or 6 months after the primary vaccination reinforced existing immunity but did not increase it beyond a certain level. The effect of the recall injection was clearly demonstrated with low doses which gave a lower level of primary immunity.  (+info)

Antibody response to antigens distinct from smooth lipopolysaccharide complex in Brucella infection. (2/138)

The smooth lipopolysaccharide complex of the outer surface of smooth Brucella abortus cells is believed to be the antigenic component involved in serological tests routinely used for the diagnosis of brucellosis. Sera from cattle vaccinated or infected with B. abortus generally contain antibody directed toward the smooth lipopolysaccharide complex. The brucella organism contains a large number of other antigenically distinct components. The biological significance of some of these antigens has been demonstrated by showing that sera from infected cattle have precipitins to these components. These sera revealed up to seven distinct lines in immunoelectrophoresis with a protein-rich antigen mixture prepared from rough strain B. abortus 45/20, whereas sera from strain 19-vaccinated cattle did not reveal these lines at 4 or more months after vaccination. Monospecific antisera were prepared against six antigens in this mixture, and the purification of two of them by antibody affinity chromatography is described.  (+info)

Protection of mice against brucellosis by vaccination with Brucella melitensis WR201(16MDeltapurEK). (3/138)

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)

Complement fixation test to assess humoral immunity in cattle and sheep vaccinated with Brucella abortus RB51. (4/138)

The live attenuated Brucella abortus strain RB51 is a rifampin-resistant, lipopolysaccharide (LPS) O-chain-deficient mutant of virulent B. abortus 2308. The reduced O-chain content in RB51 prevents this bacterium from inducing antibodies detectable by the conventional serologic tests for bovine brucellosis diagnosis that mainly identify antibodies to LPS. The absence of available serologic tests for RB51 also complicates the diagnosis of possible RB51 infections in humans exposed to this strain. The purpose of this study was to evaluate the suitability of a complement fixation (CF) test performed with the rough strain B. abortus RB51, previously deprived of anticomplementary activity, in detecting anti-B. abortus RB51 antibodies in cattle and sheep experimentally vaccinated with this strain. The results of this study showed that a CF test with RB51 as the antigen is able to specifically detect antibodies following RB51 vaccination in cattle and sheep. In addition, this method could be a useful tool for detecting B. abortus RB51 infection in humans.  (+info)

Overexpression of protective antigen as a novel approach to enhance vaccine efficacy of Brucella abortus strain RB51. (5/138)

Brucella abortus strain RB51 is an attenuated rough strain that is currently being used as the official live vaccine for bovine brucellosis in the United States and several other countries. We reasoned that overexpression of a protective antigen(s) of B. abortus in strain RB51 should enhance its vaccine efficacy. To test this hypothesis, we overexpressed Cu/Zn superoxide dismutase (SOD) protein of B. abortus in strain RB51. This was accomplished by transforming strain RB51 with a broad-host-range plasmid, pBBR1MCS, containing the sodC gene along with its promoter. Strain RB51 overexpressing SOD (RB51SOD) was tested in BALB/c mice for its ability to protect against challenge infection with virulent strain 2308. Mice vaccinated with RB51SOD, but not RB51, developed antibodies and cell-mediated immune responses to Cu/Zn SOD. Strain RB51SOD vaccinated mice developed significantly (P < 0.05) more resistance to challenge than those vaccinated with strain RB51 alone. The presence of the plasmid alone in strain RB51 did not alter its vaccine efficacy. Also, overexpression of SOD did not alter the attenuation characteristic of strain RB51.  (+info)

Brucella abortus strain RB51 as a vector for heterologous protein expression and induction of specific Th1 type immune responses. (6/138)

Brucella abortus strain RB51 is a stable, rough, attenuated mutant widely used as a live vaccine for bovine brucellosis. Our ultimate goal is to develop strain RB51 as a preferential vector for the delivery of protective antigens of other intracellular pathogens to which the induction of a strong Th1 type of immune response is needed for effective protection. As a first step in that direction, we studied the expression of a foreign reporter protein, beta-galactosidase of Escherichia coli, and the 65-kDa heat shock protein (HSP65) of Mycobacterium bovis in strain RB51. We cloned the promoter sequences of Brucella sodC and groE genes in pBBR1MCS to generate plasmids pBBSODpro and pBBgroE, respectively. The genes for beta-galactosidase (lacZ) and HSP65 were cloned in these plasmids and used to transform strain RB51. An enzyme assay in the recombinant RB51 strains indicated that the level of beta-galactosidase expression is higher under the groE promoter than under the sodC promoter. In strain RB51 containing pBBgroE/lacZ, but not pBBSODpro/lacZ, increased levels of beta-galactosidase expression were observed after subjecting the bacteria to heat shock or following internalization into macrophage-like J774A.1 cells. Mice vaccinated with either of the beta-galactosidase-expressing recombinant RB51 strains developed specific antibodies of predominantly the immunoglobulin G2a (IgG2a) isotype, and in vitro stimulation of their splenocytes with beta-galactosidase induced the secretion of gamma interferon (IFN-gamma), but not interleukin-4 (IL-4). A Th1 type of immune response to HSP65, as indicated by the presence of specific serum IgG2a, but not IgG1, antibodies, and IFN-gamma, but not IL-4, secretion by the specific-antigen-stimulated splenocytes, was also detected in mice vaccinated with strain RB51 containing pBBgroE/hsp65. Studies with mice indicated that expression of beta-galactosidase or HSP65 did not alter either the attenuation characteristics of strain RB51 or its vaccine efficacy against B. abortus 2308 challenge.  (+info)

Structural, functional and immunological studies on a polymeric bacterial protein. (7/138)

The characterization of proteins from Brucella spp, the causative agent of brucellosis, has been the subject of intensive research. We have described an 18-kDa cytoplasmic protein of Brucella abortus and shown the potential usefulness of this protein as an antigen for the serologic diagnosis of brucellosis. The amino acid sequence of the protein showed a low but significant homology with that of lumazine synthases. Lumazine is an intermediate product in bacterial riboflavin biosynthesis. The recombinant form of the 18-kDa protein (expressed in E. coli) folds like the native Brucella protein and has lumazine-synthase enzymatic activity. Three-dimensional analysis by X-ray crystallography of the homolog Bacillus subtilis lumazine synthase has revealed that the enzyme forms an icosahedral capsid. Recombinant lumazine synthase from B. abortus was crystallized, diffracted X rays to 2.7-A resolution at room temperature, and the structure successfully solved by molecular replacement procedures. The macromolecular assembly of the enzyme differs from that of the enzyme from B. subtilis. The Brucella enzyme remains pentameric (90 kDa) in its crystallographic form. Nonetheless, the active sites of the two enzymes are virtually identical at the structural level, indicating that inhibitors of these enzymes could be viable pharmaceuticals across a broad species range. We describe the structural reasons for the differences in their quaternary arrangement and also discuss the potential use of this protein as a target for the development of acellular vaccines.  (+info)

Validation of the abbreviated Brucella AMOS PCR as a rapid screening method for differentiation of Brucella abortus field strain isolates and the vaccine strains, 19 and RB51. (8/138)

The Brucella AMOS PCR assay was previously developed to identify and differentiate specific Brucella species. In this study, an abbreviated Brucella AMOS PCR test was evaluated to determine its accuracy in differentiating Brucella abortus into three categories: field strains, vaccine strain 19 (S19), and vaccine strain RB51/parent strain 2308 (S2308). Two hundred thirty-one isolates were identified and tested by the conventional biochemical tests and Brucella AMOS PCR. This included 120 isolates identified as B. abortus S19, 9 identified as B. abortus strain RB51, 57 identified as B. abortus biovar 1, 15 identified as B. abortus bv. 2, 1 identified as B. abortus bv. 2 (M antigen dominant), 7 identified as B. abortus bv. 4, and 22 identified as B. abortus S2308 and isolated from experimentally infected cattle. The Brucella AMOS PCR correctly identified each isolate as RB51/S2308, S19, or a field strain of Brucella.  (+info)

Brucella abortus is a facultative intracellular bacterial pathogen, which causes abortion in cattle and undulant fever in human. B. abortus strain RB51 (Strain RB51) is the official vaccine for bovine brucellosis in the USA. B. abortus strain RB51 can be used as a vector for the over-expression of its own (homologous) as well as heterologous protective antigens. The immune system can detect these heterologous antigens and produce a response. Expressing a protein in different bacterial compartments has been shown to affect its accessibility to the immune system and the way the antigen is processed by antigen presenting cells. In order to determine if the immune response is affected by the localization of the antigen, green fluorescent protein (GFP) was expressed at three different locations in B. abortus strain RB51, outer-membrane (OM), periplasmic space (PS) and in the cytoplasmic region (CR) of B. abortus strain RB51. This localization was obtained by transforming strain RB51 with plasmids ...
Background: Lipopolysaccharides (LPSs) and several antigenic proteins of Brucella have been considered for preparation of diagnostic reagents and subunit vaccines. The objective of this study was to identify and compare immunogens of B. abortus S19 which induce humoral immune responses in human, goat and rabbit. Material and Methods: The bacterial whole cell extract was prepared in extraction buffer and resolved using two-dimensional gel electrophoresis (2-DE). The resolved antigens were reacted against human, goat and rabbit sera using western blotting. Results: At least 19, 14 and 16 immunogenic proteins were recognized in western blotting with human, goat and rabbit sera, respectively. The most abundant proteins of the bacterium with immunogenic properties in goat and rabbit but not in human, were a group of 5-6 proteins with molecular masses of 32-34 KDa and isoelectric point (pI) ranging from 4.5 to 5.7. In contrast, a group of 5 proteins with molecular weight of 45 KDa and pI in the range of 4.5

Brucellosis is a disease that can be prevented through vaccination. Yet, the effectiveness of the vaccination to fight this disease is considered weak. Fortunately, attempts to modify brucellosis vaccine is still keep going. Some brucellosis vaccines have been found and developed in the past time such as the vaccine B.abortus strain 19-BA and 104M which was made from weakened microbes which had been widely used in Uni Soviet and China. The other brucellosis vaccine that were used in the past were the phenolinsoluble peptidoglycan vaccine which was made in France and polysaccharide-protein vaccine which was used in Russia. This research attempted to see the determinant of antigenic Outer Membrane Protein (OM) 36 kDa Brucella abortus local isolation which has immunogenic character to be developed as an advanced brucellosis vaccine. The method used in this research was the Omp2 gene of Brucella abortus of local isolate employed the PCR technique. The result of the PCR was then sequenced to analyze ...
Converts alpha-N-acetylneuranimic acid (Neu5Ac) to the beta-anomer, accelerating the equilibrium between the alpha- and beta-anomers. Probably facilitates sialidase-negative bacteria to compete sucessfully for limited amounts of extracellular Neu5Ac, which is likely taken up in the beta-anomer. In addition, the rapid removal of sialic acid from solution might be advantageous to the bacterium to damp down host responses.
Ubiquinone (UQ), also called coenzyme Q, and plastoquinone (PQ) are electron carriers in oxidative phosphorylation and photosynthesis, respectively. The quinoid nucleus of ubiquinone is derived from the shikimate pathway; 4-hydroxybenzoate is directly formed from chorismate in bacteria, while it can be formed from either chorismate or tyrosine in yeast. The following biosynthesis of terpenoid moiety involves reactions of prenylation, decarboxylation, and three hydroxylations alternating with three methylations. The order of these reactions are somewhat different between bacteria and yeast. Phylloquinone (vitamin K1), menaquinone (vitamin K2), and tocopherol (vitamin E) are fat-soluble vitamins. Phylloquinone is a compound present in all photosynthetic plants serving as a cofactor for photosystem I-mediated electron transport. Menaquinone is an obligatory component of the electron-transfer pathway in bacteria ...

The roles of humoral and cell mediated immune responses in murine brucellosis were investigated in this study.B. abortus strain 19, the current vaccine strain, is known to induce an antibody as well as cell mediated immune responses, both of which protect mice against smooth strain 2308. B. abortus rough strain RB51 does not induce an o-side chain specific antibody response and yet protects mice against smooth strain 2308. Passive transfer experiments using serum and nylon wool enriched T cells obtained from micevaccinated with strain 19 and strain RB51 were carried out. Immune senum from strain 19 vaccinated mice protected against challenge with strain 2308 but not strain RB51. Nylon wool enriched T cells from strain 19 vaccinated mice protected recipient mice against challenge with both strains RB51 or 2308.

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
The Brucella abortus strain S19, a spontaneously attenuated strain, has been used as a vaccine strain in vaccination of cattle against brucellosis for six decades. Despite many studies, the physiological and molecular mechanisms causing the attenuation are not known. We have applied pyrosequencing technology together with conventional sequencing to rapidly and comprehensively determine the complete genome sequence of the attenuated Brucella abortus vaccine strain S19. The main goal of this study is to identify candidate virulence genes by systematic comparative analysis of the attenuated strain with the published genome sequences of two virulent and closely related strains of B. abortus, 9-941 and 2308. The two S19 chromosomes are 2,122,487 and 1,161,449 bp in length. A total of 3062 genes were identified and annotated. Pairwise and reciprocal genome comparisons resulted in a total of 263 genes that were non-identical between the S19 genome and any of the two virulent strains. Amongst these, 45 genes

PHE1 is a htrA cycL double gene deletion mutant of virulent Brucella abortus strain 2308 (S2308) which has previously been evaluated in the murine and caprine models of bovine brucellosis. This report describes the results of studies conducted with this mutant in the natural bovine host. Six sexually mature, non-gravid heifers were inoculated via the conjunctival sac with 1x1010 colony forming units (CFU) of either the parental S2308 or the htrA cycL gene deletion mutant, PHE1. At 4, 7 and 11 days post-inoculation, PHE1 was found to colonize the bovine host at lower levels than S2308. In a second experiment, eight heifers in mid-gestation were infected with 1x107CFU of either strain via the conjunctival sac. The virulent S2308 caused abortions or weak calves in 4/4 cows, while all four cows infected with PHE1 had healthy calves. Furthermore, PHE1 exhibited decreased resistance to killing by cultured bovine neutrophils and macrophages compared to the parental strain. These studies demonstrate that the B.
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
Brucella abortus is a Gram-negative, facultative intracellular bacterium that causes brucellosis, a worldwide zoonotic disease leading to undulant fever in humans and abortion in cattle. The immune response against this bacterium relies on the recognition of microbial pathogen-associated molecular patterns, such as lipoproteins, lipopolysaccharides and DNA; however, the immunostimulatory potential of B. abortus RNA remains to be elucidated. Here, we show that dendritic cells (DCs) produce significant amounts of IL-12, IL-6 and IP-10/CXCL10, when stimulated with purified B. abortus RNA. IL-12 secretion by DCs stimulated with RNA depends on TLR7 while IL-6 depends on TLR7 and partially on TLR3. Further, only TLR7 plays a role in IL-12 production induced by B. abortus infection. Moreover, cytokine production in DCs infected with B. abortus or stimulated with bacterial RNA was reduced upon pretreatment with MAPK/NF-κB inhibitors. By confocal microscopy, we demonstrated that TLR7 is colocalized with B.
La mayoría de las infecciones bacterianas inducen la activación de los neutrófilos polimorfonucleares (PMN), mejoran su función microbicida y promueven la supervivencia de estos leucocitos durante períodos prolongados. Brucella abortus es un patógeno sigiloso que evade la inmunidad innata, apenas activa los PMN y resiste los mecanismos de destrucción de estos fagocitos. Los intrigantes signos clínicos que se observan durante la brucelosis son el bajo número de PMN infectados por Brucella en los órganos diana y la neutropenia en una proporción de los pacientes; características que merecen una mayor atención. Aquí demostramos que B.abortus mata prematuramente a los PMN humanos de forma dosis dependiente y específica de la célula. La muerte de los PMNs es concomitante con la liberación de lipopolisacáridos intracelulares de Brucella (Br-LPS) en vacuolas. Esta molécula y su lípido A reproducen la muerte celular prematura de los PMN, un fenómeno asociado a la baja producción de ...

Brucella abortus induces an inflammatory response that stimulates the endocrine system resulting in the secretion of cortisol and dehydroepiandrosterone (DHEA). Osteoarticular brucellosis is the most common presentation of the active disease in humans and we have previously demonstrated that B. abortus infection inhibits osteoblast function. We aimed to evaluate the role of cortisol and DHEA on osteoblast during B. abortus infection. B. abortus infection induces apoptosis and inhibits osteoblast function. DHEA treatment reversed the effect of B. abortus infection on osteoblast by increasing their proliferation, inhibiting osteoblast apoptosis and reversing the inhibitory effect of B. abortus on osteoblast differentiation and function. In contrast, cortisol increased the effect of B. abortus infection. Cortisol regulates target genes by binding to the glucocorticoid receptor (GR). B. abortus infection inhibited GR-α expression. Cells responses to cortisol not only depend on GR expression but also on its
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. ...

Brucella causes a chronic and debilitating infection that leads to great economic losses and a public health burden. In this study, we demonstrated the brucellacidal effect of heat shock mediated by the induction of pro-inflammatory cytokines, reactive oxygen species (ROS) accumulation and apoptosis in murine macrophages and in mice. RAW264.7 cells were incubated at 43 °C, and BALB/c mice were subjected to whole body hyperthermia. The data showed a reduction in bacterial survival in the mice after daily heat exposure. This was accompanied by increased levels of cytokines TNF, IL-6, IL-1β and IFN-γ in the sera of the mice. Gene expression of NF-κB and inducible nitric oxide production were also induced in the mouse splenic cells. In parallel with the bacterial reduction in the mouse model, an increased bactericidal effect was observed in RAW264.7 cells after exposure to heat stress. In addition, the heat stress increased both the nuclear translocation of NF-κB and the expression of the heat shock
In this study, we isolated and characterized B. abortusRA1, a transposon-derived rough mutant of standard strain 2308. We further identified the gene disrupted by Tn5 in strain RA1 as wboA, which encodes a putative glycosyltransferase, an enzyme which appears to be essential for the biosynthesis of the O side chain in B. abortus. LPS analysis of strains RA1 and RB51 indicated that both strains lack the O side chain. However, the reason for the presence of the intermediate LPS band in strain RA1 that is lacking in strain RB51 is not known (Fig. 1). One possibility is that the mutation in strain RA1 results in exposure of a glycose that can be glycosylated by glycosyltransferases that are not able to attach specific sugars in the parent or in strain RB51. The result may be a side branch in the core, generating a new glycoform. Evidence for this is the relatively high amount of galactose present in RA1, whereas only a trace amount of this glycose is present in RB51. Unfortunately, the nature of the ...

Neurobrucellosis, which is the most morbid form of brucellosis disease, presents with inflammatory signs and symptoms. Recent experimental evidence clearly indicates that deregulation of astrocytes and microglia caused by Brucella infection creates a microenvironment in the central nervous system (CNS) in which secretion of pro-inflammatory mediators lead to destabilization of the glial structure, the damage of the blood brain barrier (BBB) and neuronal demise. This review of Brucella interactions with cells of the CNS and the BBB is intended to present recent immunological findings that can explain, at least in part, the basis for the inflammatory pathogenesis of the nervous system that takes place upon Brucella infection. [Cerrar ...
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 ...
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 ...

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.
Bacillus anthracis is a facultative intracellular bacterial pathogen that can cause cutaneous, gastrointestinal or respiratory disease in many vertebrates, including humans. Commercially available anthrax vaccines for immunization of humans are of limited duration and do not protect against the respiratory form of the disease. Brucella abortus is a facultative intracellular bacterium that causes chronic infection in animals and humans. As with other intracellular pathogens, cell mediated immune responses (CMI) are crucial in affording protection against brucellosis. B. abortus strain RB51 has been shown to be useful in eliciting protective cell mediated immunity and humoral responses against Brucella in cattle and other animal species. Since the protective antigen (PA) of B. anthracis is known to induce protective antibodies, it was decided that the objective of this research was to test whether the gene encoding PA could be expressed in Brucella producing a bivalent vaccine to protect against ...
Serological test is one of diagnostic method to detect pathogenicity brucella. Several methods are being improving such as Rose Bengal Test (RBT), Complement Fixation Test (CFT) dan Enzyme-linked Immunosorbent Assay (ELISA). Immunostick has an accuracy equivalent to ELISA and is easy to apply in the field so it is possible to be applied as a rapid test for brucellosis detection. The study aim was to know sensitivity and specificity of immunostick that were used to detecte antibody Brucella abortus using commercial antigens of B. abortus Strain 19 (S19) and B. abortus Strain 99 (S99). The test have compared with ELISA. The tests were conducted in two stages, namely (i) immunostick ability to detect antibodies in seropositive and seronegative serum, and (ii) the immunostick result were compared with ELISA result in serum grup that were be know and unknown status. A total of 250 serums were examined and result indicated that immunostick can be detect B. abortus antibodies in cattle serum with ...
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
We present a rare case of brucella endocarditis, forming a vegetation on the mitral valve. The definitive diagnosis has been made with clinical suspicion, positive serology, the demonstration of the vegetation with the echocardiography and with the production from the multiple blood culture of brucella melitensis and from the excised valve. Our patient has been successfully treated with specific antibiotherapy and the surgery of replacement of mitral valve. 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 ...

In this study, we explore the regulatory roles of pro-inflammatory cytokine tumor necrosis factor alpha (TNF) in the innate immunity of macrophages against B. abortus infection. We show that infection of macrophage with B. abortus induces marked expression and secretion of TNF which subsequently binds to TNF receptor 1 (TNFR-1) and activates a downstream signaling cascade of the innate immunity. Blocking of TNF signaling resulted in a notable increase of B. abortus survival which was associated with an increase of anti-inflammatory cytokine interleukin 10 (IL-10), a beneficial effector of Brucella survival, as well as remarkable decrease of reactive oxygen species (ROS) and nitric oxide (NO), antibrucella molecules ...
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. ...
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 ...
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

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 ...
