Brucella spp. are facultative intracellular bacterial pathogens causing the zoonotic disease brucellosis. Here, we report the draft genome sequence of the Brucella melitensis strain from India designated Bm IND1, isolated from stomach contents of an aborted goat fetus.

A comparative study was conducted using data from naive bison (n = 45) and cattle (n = 46) from 8 and 6 studies, respectively, in which a standardized Brucella abortus strain 2308 experimental challenge was administered during midgestation. The incidence of abortion, fetal infection, uterine or mammary infection, or infection in maternal tissues after experimental challenge was greater (P < 0.0...

Most bacterial infections induce the activation of polymorphonuclear neutrophils (PMNs), enhance their microbicidal function, and promote the survival of these leukocytes for protracted periods of time. Brucella abortus is a stealthy pathogen that evades innate immunity, barely activates PMNs, and resists the killing mechanisms of these phagocytes. Intriguing clinical signs observed during bruc...

Brucellosis is one of the important zoonotic diseases among livestock. This study was carried out to estimate the prevalence of brucellosis and isolate Brucella spp. in sheep in Kassala State in the east of Sudan. Two thousand and five serum samples were randomly collected from nine different localities. All serum samples were examined by the Rose Bengal plate test (RBPT) and the modified RBPT ...

Brucella abortus and Mycobacterium bovis are zoonotic pathogens that cause Brucellosis and Tuberculosis in cattle respectively. Besides being a serious public health threat, these agents cause significant economic losses throughout the world. Here we use the fluorescence polarization capabilities of the SynergyTM 2 Multi-Mode Microplate Reader to run Brucella and Mycobacterium bovis antibody de...

As Brucella infections occur mainly through mucosal surfaces, the development of mucosal administered vaccines could be radical for the control of brucellosis. In this work we evaluated the potential of Brucella abortus 19 kDa outer membrane protein (U-Omp19) as an edible subunit vaccine against brucellosis. We investigated the protective immune response elicited against oral B. abortus infecti...

OBJECTIVE--To determine the feasibility of qualifying individuals or groups of Yellowstone National Park bison as free from brucellosis. DESIGN--Cohort study. SAMPLE--Serum, blood, and various samples from live bison and tissues taken at necropsy from 214 bison over 7 years. PROCEDURES--Blood was collected from bison every 30 to 45 days for serologic tests and microbiological culture of blood f...

As part of a Brucella abortus 2308 genome project carried out in our laboratory, we identified, cloned, and sequenced a genomic DNA fragment containing a locus (virB) highly homologous to bacterial type IV secretion systems. The B. abortus virB locus is a collinear arrangement of 13 open reading frames (ORFs). Between virB1 and virB2 and downstream of ORF12, two degenerated, palindromic repeat ...
