Brucella suis (B. suis) is the major cause of porcine brucellosis. Zoonosis due to B. suis infection associated with transmission by various animal species is reported. Recently an increase in brucellosis associated with feral swine transmitted B. suis infection in humans and hunting dogs is emerging. Reports on B. suis infection in carnivores including dogs is scant. This report gives a brief ...
Brucella species are the most important zoonotic pathogens worldwide and cause considerable harm to humans and animals. In this study, we presented the complete genome of B. suis 019 isolated from sheep (ovine) with epididymitis. B. suis 019 has a rough phenotype and can infect sheep, rhesus monkeys and possibly humans. The comparative genome analysis demonstrated that B. suis 019 is closest to...
Importance of urease activity on pathogenic differences among Brucella species was evaluated. In cell-free extracts, the B. suis urease showed 12 times greater specific activity than the B. melitensis urease. When Fisher-344 rats were inoculated intraperitoneally (IP), at 1 week post-inoculation (PI), B. melitensis wild type 16 M was recovered from spleens and livers in greater numbers than B. ...
The cellular fatty acid composition of Brucella canis and Brucella suis was determined by gas-liquid chromatography. The presence of relatively large amounts of a 19-carbon cyclopropane fatty acid in B. suis was a major distinguishing feature between these organisms. The gas-liquid chromatography test for cellular fatty acids provides an additional criterion for the distinction of antigenically...
INTRODUCTION Brucella suis is the causative agent of brucellosis in suidae and is differentiated into five biovars (bv). Biovars 1 and 3 possess zoonotic potential and can infect humans, whereas biovar 2 represents the main source of brucellosis in feral and domestic pigs in Europe. Both aspects, the zoonotic threat and the economic loss, emphasize the necessity to monitor feral and domestic pi...
Analysis of a Brucella suis 1330 gene fused to a gfp reporter, and identified as being induced in J774 murine macrophage-like cells, allowed the isolation of a gene homologous to nikA, the first gene of the Escherichia coli operon encoding the specific transport system for nickel. DNA sequence analysis of the corresponding B. suis nik locus showed that it was highly similar to that of E. coli e...
results we found 28 cases with positive results for b. melitensis by multiplex pcr technique which was significantly different from of sat (p<0.05). six samples were positive for b. abortus by pcr. conclusion the results of present study showed that multiplex pcr assay is a rapid and sensitive technique for diagnosis of brucellosis compared to sat. however it is more accurate when coupled with ...
Helicobacter (H.) suis can colonize the stomach of pigs as well as humans, causing chronic gastritis and other gastric pathological changes including gastric ulceration and mucosa-associated lymphoid tissue (MALT) lymphoma. Recently, a virulence factor of H. suis, γ-glutamyl transpeptidase (GGT), has been demonstrated to play an important role in the induction of human gastric epithelial cell d...
Content Update: June 15, 2007 Importance Porcine brucellosis, caused by the bacterium Brucella suis, is an economically important cause of reproductive loses in pigs. This organism can be maintained in wild and feral swine, complicating eradication efforts in domesticated pigs. One variant, found only in Europe, is also maintained in hares. Some variants of B. suis mainly affect caribou, reinde...
The 3.31-Mb genome sequence of the intracellular pathogen and potential bioterrorism agent, Brucella suis, was determined. Comparison of B. suis with Brucella melitensis has defined a finite set of differences that could be responsible for the differences in virulence and host preference between these organisms, and indicates that phage have played a significant role in their divergence. Analys...
