Safety of Brucella abortus strain RB51 in black bears.

In two studies conducted from October 1999 to March 2000 and December 2000 to April 2001, adult black bears (Ursus americanus) were orally inoculated with 1.4-3.1 x 10(10) colony-forming units (CFU) of Brucella abortus strain RB51 (SRB51, n=12) or 2 ml of 0.15 M NaCl solution (saline, n=11). We did not detect a difference (P>0.05) in antibody titers to SRB51 in serum obtained before vaccination...

Safety of revaccination of pregnant bison with Brucella abortus strain RB51.

From December 1998 through February 1999, a study was conducted in a Brucella-infected bison herd to evaluate the safety of booster vaccination of adult bison (Bison bison) with 6 x 10(9) colony forming units (CFU) of Brucella abortus strain RB51 (SRB51) that had previously been vaccinated as yearlings with 1 x 10(10) CFU of SRB51. Abortions or other adverse effects were not observed after SRB5...

Safety and immunogenicity of Brucella abortus strain RB51 vaccine in cross bred cattle calves in India.

Safety and immunogenicity of Brucella abortus RB51 vaccine has been evaluated in an organised dairy farm in India. All the cattle (r = 29) vaccinated with strain RB51 'responded' to the vaccine as demonstrated by iELISA using acetone killed strain RB51 antigen. The percentage responders at day 35, 60 and 90 post vaccination were 100%, 95% and 20%, respectively. Strain RB51 was able to elicit a ...

Safety of Brucella abortus strain RB51 vaccine in non-target ungulates and coyotes.

Brucellosis is endemic in free-ranging elk (Cervus elaphus) and bison (Bison bison) in the Greater Yellowstone Area (GYA; USA). It is possible that an oral brucellosis vaccine could be developed and disseminated in the GYA to reduce disease transmission. Should this occur, non-target species other than elk and bison may come in contact with the vaccine resulting in morbidity or mortality. To as...

Immune 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...
