Summary. The investigations were carried out to study the features of presentation of brucellosis in reindeer during bringing of the agent in well-being herds. The work was done directly under conditions of tundra during the expedition trips in reindeer crews of MRBE «Yarsalinskoe» in Yamal district of Yamalo-Nenets Autonomous District and in the laboratory of ecology of All-Russian Research Institute of Brucellosis and Tuberculosis of Animals. Serological and bacteriological studies were performed by conventional methods. The identification of sporadic cases of positively reacting animals in herds of reindeer (up to 0.6 %), located on the stationary free from brucellosis territory, is connected with the bringing of infection during animal migration, in particular with uncontrolled regrouping of deer from private and common herds. The inclusion of veterinary measures in the technological process of company for slaughtering allowed improving the efficiency of control for epizootic situation, identifying the animals at early stages of brucellosis, establishing the fact of introduction of the agent in the safe herd, timely arresting the center of infection and preventing its spread among susceptible livestock. We used standard brucellosis (S-) antigens and serum diagnostic kits as diagnosticums. With the introduction of brucellosis agent in free herds the infection nidus formed with the spread up to 0.6 %. During the first months of infection, in the majority of infected animals (60 %) the specific brucellosis immunoglobulins of different classes were identified. With the development of infection in the half of seropositive animals the activity of antibody trapped in agglutination reaction was reduced to minimal diagnostic titers and the activity of complement-fixing antibodies increased to 1:20 – 1: 320. These indicators show the generalization of infection and the initial stage of the transition of acute course to chronic one.
Keywords: reindeer, brucellosis, nidus of infection, epizootic process.
