APPLICATION OF LIVING AGGLUTINOGENIC VACCINE OF B.ABORTUS 19 STRAINS IN IMMUNIZATION OF REINDEERS’ BRUCELLOSIS
Investigations were carried out in unfavorable brucellosis farm “Zhigansk” Zhigansky region of the Republic of Sakha (Yakutia), where 280 heads of deer were vaccinated at the age of 6–8 months by vaccine B.abortus 19 strain. The purpose of research is the use of a live vaccine from strain agglutinogens B.abortus 19 at immunization brucellosis reindeer. Periodically for 3 years were clinical observations of the animals vaccinated and serological studies in BPO, RA and RAC. The results showed that after 8 months of an immunized 1/3 calves reacted positively by BPO, and then watched the natural decrease in their number to 45 month of the greatest number of animals responded to RAC — 10.6 %. The use of a living agglutinogenic vaccine from B.abortus 19 strain shows that the vaccinated deer, regardless of gender and age, their immune system creates a sufficient intensity and duration (from 8 to 17 months) and has a high anti-epizootic efficiency. Along with this, the vaccine is expressed by the reactogenicity for the organism of reindeer, depending on the dose, it causes inhibition of their general state, a part of them — claudication, bursitis, tenosynovitis; persisting in the blood of agglutinins and complement-fixing antibodies. But the introduction of a low dose of 8 milliard m. k. has a high anti-epizootic efficiency.
