Brucella spp. are intracellular bacterial pathogens that cause infection in domestic and wild animals. They are often used as model organisms to study intracellular bacterial infections. Brucella VirB T4SS is a key virulence factor that plays important roles in mediating intracellular survival and manipulating host immune response to infection. In this review, we discuss the roles of Brucella V...

A multi-agency investigation followed the notification of four locally acquired human brucellosis cases in north-west NSW. Feral pig hunting within a geographically discrete region was identified as the likely exposure with Brucella suis the suspected cause. To test whether feral pigs in the region were infected with Brucella, serological testing was performed on trapped feral pigs and testicul...

Investigation of a clinical case of Brucella infection, in which the cause initially indicated Bordetella bronchiseptica, using automated identification techniques prompted a retrospective analysis of previously published cases of B. bronchiseptica infections in China and elsewhere. B. bronchiseptica infection is rarely found in humans, but more frequently in animals. Automated microbial identi...

A case is presented of brucella arthritis of the knee in a young soccer player. The diagnosis is outlined, together with possible errors of observation.

BACKGROUND: Brucellosis is a febrile zoonotic infectionand has worldwide distribution among humans as well asanimals. Although the seroprevalence of brucellosis in variousanimals has been described in Iran, there is only one report onequine brucellosis in the region. OBJECTIVES: This study wascarried out to determine the seroprevalence of brucellosis inracing clubs and private horse owners in t...

Brucella spp infections of marine mammals are often asymptomatic but have been associated with reproductive losses and deaths. Zoonotic infections originating from marine isolates have also been described. Hector's dolphins (Cephalorhynchus hectori) are an endangered species with a declining population, and the role of infectious disease in population dynamics is not fully understood. In this s...

Brucellosis is a zoonosis caused by the bacteria belonging to the genus Brucella. 1 Currently there are six recognized species of Brucellaebased on phenotypic characteristics, antigenic variations and prevalence of infection in different animal hosts. Brucella abortusin cattles, Brucella melitensis in sheep and goats, Brucella suis in pigs, Brucella canis in dogs, Brucella ovis in sheep and Bru...

Brucella spp. are stealthy bacteria that enter host cells without major perturbation. The molecular mechanism involved is still poorly understood, although numerous studies have been published on this subject. Recently, it was reported that Brucella abortus utilizes cellular prion protein (PrP(C)) to enter the cells and to reach its replicative niche. The molecular mechanisms involved were not ...

Human brucellosis is a neglected zoonotic disease and has widespread geographical distribution. Brucella melitensis has caused outbreaks and sporadic cases in Malaysia. Here, we present the whole-genome sequences of four B. melitensis strains isolated from brucellosis patients in Malaysia.

AIM To describe the various strategies for the control and eradication of B. melitensis infection in sheep and goats. METHODS The advantages and drawbacks of these strategies are discussed on the basis of the author's personal experience and a revision of the relevant literature. RESULTS Vaccination programmes in various combinations can be applied either to decrease the prevalence of infec...
