Immune responses of bison and efficacy after booster vaccination with Brucella abortus strain RB51.
Thirty-one bison heifers were randomly assigned to receive saline or a single vaccination with 10(10) CFU of Brucella abortus strain RB51. Some vaccinated bison were randomly selected for booster vaccination with RB51 at 11 months after the initial vaccination. Mean antibody responses to RB51 were greater (P < 0.05) in vaccinated bison after initial and booster vaccination than in nonvaccinated...
متن کاملImmune responses and safety after dart or booster vaccination of bison with Brucella abortus strain RB51.
One alternative for management of brucellosis in Yellowstone National Park bison (Bison bison) is vaccination of calves and yearlings. Although Brucella abortus strain RB51 vaccination protects bison against experimental challenge, the effect of booster vaccinations was unknown. This study characterized immunologic responses after dart or booster vaccination of bison with Brucella abortus strai...
متن کاملImmune responses of elk to initial and booster vaccinations with Brucella abortus strain RB51 or 19.
Previous studies have suggested that currently available brucellosis vaccines induce poor or no protection in elk (Cervus elaphus nelsoni). In this study, we characterized the immunologic responses of elk after initial or booster vaccination with Brucella abortus strains RB51 (SRB51) and 19 (S19). Elk were vaccinated with saline or 10(10) CFU of SRB51 or S19 (n=seven animals/treatment) and boos...
متن کاملComplement fixation test to assess humoral immunity in cattle and sheep vaccinated with Brucella abortus RB51.
The live attenuated Brucella abortus strain RB51 is a rifampin-resistant, lipopolysaccharide (LPS) O-chain-deficient mutant of virulent B. abortus 2308. The reduced O-chain content in RB51 prevents this bacterium from inducing antibodies detectable by the conventional serologic tests for bovine brucellosis diagnosis that mainly identify antibodies to LPS. The absence of available serologic test...
متن کاملPost-exposure serological and bacteriological responses of water buffalo (Bubalus bubalis) to Brucella abortus biovar 1 following vaccination with Brucella abortus strain RB51.
Serological and bacteriological responses to Brucella abortus biovar 1 following vaccination with B. abortus strain RB51 (RB51) were evaluated in thirty domestic water buffalo (Bubalus bubalis) randomly divided into five treatment groups. Groups I to V received, respectively, the recommended dose (RD) of RB51 vaccine once, RD twice 4 weeks apart, double RD once, double RD twice 4 weeks apart, a...
