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 کاملVaccination of Elk (Cervus canadensis) with Brucella abortus Strain RB51 Overexpressing Superoxide Dismutase and Glycosyltransferase Genes Does Not Induce Adequate Protection against Experimental Brucella abortus Challenge
In recent years, elk (Cervus canadensis) have been implicated as the source of Brucella abortus infection for numerous cattle herds in the Greater Yellowstone Area. In the face of environmental and ecological changes on the landscape, the range of infected elk is expanding. Consequently, the development of effective disease management strategies for wild elk herds is of utmost importance, not o...
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 کاملExperiences in Mexico of the vaccination in bovines and goats, with Brucella abortus RB51 strain
The control of brucellosis in Mexico since the 70's until 1998 was performed using cattle vaccination with S19 strain of Brucella abortus as a key tool. The use of strain RB51 was approved since 1998 and vaccination with strain S19 was gradually decreased until fully waived. The strain S19 was used again from 2005 and now both vaccines are applied equally to prevent brucellosis in Mexican cattl...
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...
