Experimental infection of nontarget species of rodents and birds with Brucella abortus strain RB51 vaccine.
The Brucella abortus vaccine strain RB51 (SRB51) is being considered for use in the management of bnucellosis in wild bison (Bison bison) and elk (Cervus elaphus) populations in the Greater Yellowstone Area (USA). Evaluation of the vaccines safety in non-target species was considered necessary prior to field use. Between June 1998 and December 1999, ground squirrels (Spermophilus richardsonii, ...
متن کاملSafety 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 ...
متن کاملSerologic responses in diagnostic tests for brucellosis in cattle vaccinated with Brucella abortus 19 or RB51.
Serologic responses in the particle concentration fluorescence immunoassay and the card, complement fixation, and tube agglutination tests were measured for 10 weeks after vaccination of cattle with either Brucella abortus 19 or the lipopolysaccharide O-antigen-deficient mutant, strain RB51. The responses of strain 19-vaccinated cattle were positive, whereas those of strain RB51-vaccinated catt...
متن کاملComparison of the efficacy of Brucella abortus strain RB51 and Brucella melitensis Rev. 1 live vaccines against experimental infection with Brucella melitensis in pregnant ewes.
To test the efficacy of rough Brucella strain vaccines in sheep, a vaccine recently developed in cattle (Brucella abortus strain RB51) was assessed in comparison with the conventional Rev. 1 vaccine. Forty-five ewes from twelve to fourteen months of age, from brucellosis-free flocks, were allotted to three groups of fifteen ewes each. Group one was vaccinated by the conjunctival route with 1.73...
متن کاملSafety 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...
