Polymeric antigen BLSOmp31 in aluminium hydroxide induces serum bactericidal and opsonic antibodies against Brucella canis in dogs

Neisseria gonorrhoeae NspA induces specific bactericidal and opsonic antibodies in mice.

Neisseria gonorrhoeae surface protein A (NspA) is a highly conserved gonococcal antigen. To explore the potential of NspA in vaccine development against gonorrhea, BALB/c mice were immunized with pcNspA containing the NspA gene from N. gonorrhoeae strain WHO-A via intramuscular (i.m.) injection, intranasal (i.n.) immunization, or intravaginal (i.vag.) immunization. Following the last DNA immuni...

A serological survey on Brucella canis in companion dogs in Ahvaz

Canine brucellosis is a zoonotic infectious disease caused by Brucella canis. This bacterium can be transmitted to humans as well as other dogs. It is a significant cause of reproductive failure, predominantly in kennels. The aim of this study was to determine the seroprevalence of Brucella canis infection in companion dogs referred to the Veterinary Hospital of Shahid Chamran University of Ahv...

Comparison between a soluble antigen-based ELISA and IFAT in detecting antibodies against Babesia canis in dogs.

An available enzyme-linked immunosorbent assay (ELISA) was studied for the detection of anti-B. canis antibodies in the sera of dogs using, indirect fluorescent antibody test (IFAT) as a reference test. ELISA uses a soluble antigenic preparation of B. canis and the optimal dilutions of the antigen, serum and conjugate were determined by check board titration, using positive and negative referen...

Human Brucella canis outbreak linked to infection in dogs.

The zoonotic risk of Brucella canis has been considered fairly high for persons who handle breeding dogs in kennels or are exposed to infected animals. Transmission to humans in other circumstances has been thought to be rare. We describe an uncommon outbreak of brucellosis caused by B. canis which, to the best of our knowledge, is the first reported in the literature. This outbreak involved si...
