Abstract EN
In this study field application of RB51 vaccine combined with the policy of test and slaughter as well as application of hygienic measures for control of bovine brucellosis were carried out and evaluated in a dairy herd of cattle for two years.
Serological examination of 1280 cattle using tube agglutination buffered acidified plate antigen, Rose Bengal plate antigen and Rivals tests revealed 240 (18.75 %) positive animals with a previous history of abortion of 12 cows.
Brucella melitensis beaver 3 could be isolated from tissue specimens of slaughtered cows.
Animals that tested negative in the first examination were vaccinated with RB 51 vaccine with periodical examination every three weeks and slaughtering of positive cases.
New positive cows continued to develop up to the 5th examination then three successive sero-negative tests were obtained with release of the farm from quarantine.
Examination of animals 6, 12, 18 and 24 months post release of quarantine revealed 2, 0, 3 and one positive cases respectively the matter which clarified that the control of the outbreak using RB51 vaccine associated with policy of test and slaughter and application of hygienic measures showed some limitations.
