Reindeer husbandry is the leading branch of agriculture for the regions of the Far North. Reindeer (Rangifer tarandus) remains poorly studied from the point of view of genetics and reproduction, which hinders the intensification of development of the industry. Research is being actively conduct in the field of genetics of the productive qualities of reindeer, but the formation and functioning of its reproductive system has been little study. Hormonal regulation of the reproductive process and the formation of hormonal status at key stages of the reproductive cycle is a significant aspect of animal reproduction. Reindeer are characterized by a pronounced seasonality of reproduction, and the study of hormonal regulation of the reproductive cycle is the main aspect of the further use of assisted reproductive technologies. The work is devoted to the analysis of the level of anti-Mullerian hormone in females during the breeding season. The studies were carried out on reindeer farms of the MAU “Directorate of the Territory of Traditional Natural Resources Management of Soyots”, Buryatia, (female, n=29). The dependence of the concentration of anti-Müllerian hormone (AMH), which is a generally accepted indicator of the female ovarian reserve, on the concentration of sex hormones (progesterone, estradiol, testosterone and luteinizing hormone) in the blood serum of females was study. Hormone levels were determined by enzyme immunoassay. A higher content of sex hormones - testosterone, estradiol, progesterone and luteinizing hormone was revealed in the group of women with an AMH concentration of >1 ng/ml than in the group of women with an AMH concentration of <1 ng/ml. The significance of the differences in progesterone was p<0.05, and in estradiol – p<0.001. A low concentration of AMH (<1 ng/ml), characterizing a reduced ovarian reserve of female reindeer, corresponds to a reduced concentration of sex hormones that support reproductive function, and, conversely, a high concentration of AMH (>1 ng/ml), and, accordingly, a high ovarian reserve the reserve corresponds to an increased concentration of sex hormones - testosterone, estradiol, progesterone and luteinizing hormone.

“…microbial cells during subcutaneous administration. As a result of studies, it was found that the vaccine is harmless to this animal species and causes immunobiological changes in the body, accompanied by the production of agglutinins in high titers (1800-3200 IU/ml) and complement-binding antibodies [3,4,6]. During the entire observation period (5 months) after immunization, the number of animals showing resistance to infection with the virulent Brucella 010 culture was 80% of reindeer.…”

Living vaccines are not widely used in practice to prevent and control brucellosis in domesticated reindeer. Brucellosis vaccines from strains 19 or 82 are characterized by a high level of reactogenicity and lead to complications in vaccinated animals. When studying the reactogenic properties of the vaccine from the B. suis 245 strain in the experiment on reindeer, the reaction of the body of domesticated reindeer to the subcutaneous injection of brucella from the B. suis 245 strain was considered. At the same time, no significant differences were observed when the vaccine was administered at a dosage of 10 and 50 billion microbial cells, and the size of edema in millimeters was fixed at the level of 39.0 ± 3.5 and 44.1 ± 2.6, respectively (P> 0.05). The dynamics of the body temperature of animals depending on the method of administration and dose of the vaccine, regardless of the dosage, body temperature, like other indicators of a physiological nature, remained within the normal range. It was found that in the early stages after vaccination, the indicators of the physiological state of the animal’s body are determined by whether the oral or subcutaneous method of administration of the vaccine was used. When vaccinated by the subcutaneous method, reactogenicity was less pronounced with the introduction of 5 billion microbial cells, compared with a dose of 50 billion microbial cells.

ЭПИДЕМИОЛОГИЯ 892017, issue 1 несмотря на то, что заболеваемость сибирской язвой животных и людей в российской Федерации доведена до спорадического уровня, риски ослож-нения ситуации по-прежнему сохраняются [7,9]. это подтвердила имевшая место летом 2016 г. вспышка сибирской язвы, возникшая на полуостро-ве ямал. выявить причины и условия осложнения эпизоотолого-эпидемиологической ситуации, а так-же прогнозировать возможные негативные послед-ствия позволяет методология оценки рисков [1,10,11]. стало очевидным, что заключение об отсут-ствии или наличии той или иной степени опасности заражения сибирской язвой населения должно бази-роваться на результатах динамического изучения це-лого комплекса известных факторов риска. к их чис-лу относятся социально-экономические, природно-климатические и биологические факторы.цель исследования -определение причин и усло-вий осложнения эпизоотолого-эпидемиологической ситуации по сибирской язве на ямале путем ком-плексной оценки риска. цель исследования. анализ эпизоотологических и эпидемиологических рисков, способствовав-ших развитию вспышки сибирской язвы на полуострове ямал в июле-августе 2016 г. материалы и методы. для анализа рисков использовался комплексный подход, позволивший по материалам лите-ратурных, архивных, а также статистических данных в динамике оценить действие эпидемиологи-чески значимых социальных, природных и биологических рисков. особое внимание уделено оценке природно-климатических факторов, способствующих сохранению возбудителя в окружающей среде, таких как индекс NDVI, температура и влажность воздуха, а также почвы на различной глубине по дан-ным спутникового мониторинга. результаты и выводы. подтверждена гипотеза о стационарном не-благополучии почвенных очагов ямала, сохраняющейся опасности осложнения эпизоотологической и эпидемиологической ситуации по сибирской язве на фоне меняющихся природных и социальных фак-торов риска, а также способности возбудителя выживать в почве неопределенно длительное время.Ключевые слова: сибирская язва, B. anthracis, вспышка, ямал, эпизоотологические и эпидемиологи-ческие риски, природные и социальные факторы, биологическая опасность. Objective of the study was to analyze epizootiological and epidemiological risks contributing to the development of anthrax outbreak in the Yamal peninsular in July-August, 2016. Materials and methods. Risks were evaluated using complex approach allowing for determination of the impact of epidemiologically significant social, natural, and biological risks, based on literature sources, archival data, and statistical reports. Special focus was on the natural-climatic factors, providing for persistence of the agent in the environment, such as NDVI index, atmospheric temperature and humidity, as well as soil temperature and moisture at different depths, in accordance with satellite monitoring. Results and conclusions. Justified was the hypothesis on sustained adversity of soil foci in Yamal, remaining hazard of aggravation of epizootiological and epidemiological situation on anthrax against the ba...
