Arctic foxes (Vulpes lagopus) are susceptible to smooth Brucella (s-Brucella) infection and may be exposed such bacteria through the consumption of infected marine mammals, as implied by finding s-Brucella antibodies in polar bears (Ursus maritimus). Svalbard have not previously been investigated for s-Brucella antibodies, but antibodies detected Iceland, Alaska (USA) Russia...

B rucellosis is a zoonotic disease caused by Brucella spp. and is still a serious problem of public health for some regions around the world such as the Mediterranean Sea, Middle East, Latin America, and Asia (1). These pathogenic bacteria can infect humans as well as sheep, goats, etc. B. melitensis (sheep and goats) is the most important causative agent for human brucellosis and is followed b...

Abstract Brucella spp. are facultative intracellular bacterial pathogens that have the ability to survive and multiply in professional nonprofessional phagocytes. Successful invasion chronic persistence indicate manipulates various host cellular processes create a replication permissive niche. The essential mechanisms factors support of remain poorly understood. RNA interference (RNAi) is poten...

Sonically treated and saline-extracted antigens of Brucella ovis, B. canis, B. abortus, and B. melitensis were compared in gel diffusion, complement fixation, and serum absorption tests. All the sonically extracted antigens showed cross-reactions with sera from animals infected or immunized with these species, whereas the saline-extracted antigens were specific for the surface of the rough or s...

Agrobacterium, Sinorhizobium, and Ochrobactrum are genera closely related to Brucella but, in contrast to the latter, are not pathogenic for humans and animals. We studied by an indirect enzyme-linked immunosorbent assay (ELISA) the reactivities of brucellosis sera against cytosolic (CYT) and membrane (MA) antigens from these nonpathogenic bacteria, and we evaluated the potential usefulness of ...

With the aim of developing quantitative PCR methods for the detection and differentiation of Brucella species, the genomes of Brucella ceti, Brucella inopinata, Brucella netotomae, and Brucella suis biovar 4 were sequenced and analyzed.
