A modified Rose Bengal test (mRB) and an indirect ELISA (iELISA) with Protein G as the conjugate, were evaluated for the diagnosis of Brucella melitensis infection in unvaccinated sheep with a known bacteriological status, and their diagnostic efficacy was compared with that of the standard Rose Bengal (RB) and Complement Fixation (CF) tests used in the current eradication campaign in EU countr...
Brucella melitensis has been reported in limited cases of rhythm device infection and has been described as being insidious in its progression. In this report, we emphasize the role of tissue and pocket-fluid extended cultures, especially in patients coming from brucella-endemic areas. While tissue cultures may confirm diagnosis in these patients, they typically have negative blood and swab cul...
The Brucella melitensis sucB gene encoding the dihydrolipoamide succinyltransferase (E2o) enzyme (previously identified as an immunogenic protein in infected sheep) was cloned and sequenced. The amino acid sequence predicted from the cloned gene revealed 88.8 and 51.2% identity to the dihydrolipoamide succinyltransferase SucB protein from Brucella abortus and Escherichia coli, respectively. Ser...
To determine the most prevalent biovar responsible for brucellosis in sheep and goat populations of Iran, a cross-sectional study was carried out over 2 years in six provinces selected based on geography and disease prevalence. Specimens obtained from referred aborted sheep and goat fetuses were cultured on Brucella selective media for microbiological isolation. Brucellae were isolated from 265...
Brucellae replicate in a vacuole derived from the endoplasmic reticulum (ER) in epithelial cells, macrophages, and dendritic cells. In animals, trophoblasts are also key cellular targets where brucellae efficiently replicate in association with the ER. Therefore, we investigated the ability of Brucella spp. to infect human trophoblasts using both immortalized and primary trophoblasts. Brucella ...
Zoonotic pathogens are frequently hypothesized as emerging with the origins of farming, but evidence of this is elusive in the archaeological records. To explore the potential impact of animal domestication on zoonotic disease dynamics and human infection risk, we developed a model simulating the transmission of Brucella melitensis within early domestic goat populations. The model was informed ...
OBJECTIVES The aim of this study was to characterize by classical biotyping and Multi-Locus variable number tandem repeats (VNTR) Analysis (MLVA) all Brucella spp. derived from human cases in Belgium from 1996 to 2015. Final goals were to determine the species and biovar, to trace-back on genetic grounds the origin of each strain when patient history and risk factors were missing, and to survey...
Five serological assays were evaluated for the diagnosis of brucellosis in goats: the rose bengal test (RBT), complement fixation test (CFT), radial immunodiffusion (RID) with Brucella and Yersinia enterocolitica O:9 polysaccharides, counterimmunoelectrophoresis (CIEP) with cytosol, and enzyme-linked immunosorbent assay (ELISA) with polyclonal and protein G conjugates and smooth lipopolysacchar...
Introduction: brucella endocarditis is a rare but severe complication of brucellosis. Although it is observed in less than 2% of the brucellosis cases, it is the main cause responsible for up to 80% of infection-related deaths in brucellosis. case report: Herein, we present a case of brucella endocarditis that developed on a native aortic valve. the diagnosis was proven by positive blood cultur...
background and objectives: brucella melitensis infection is still a major health problem for human and cattle in developing countries and the middle east. materials and methods: in this study, in order to screen immunogenic candidate antigens for the development of a brucella subunit vaccine, a cytoplasmic protein (dnak) and an outer membrane protein (omp31) of b. melitensis were cloned, expres...
