Abstract
The paper presents the results of the study and analysis of the epizootic process of anthrax among domestic animals in the Republic of Sakha (Yakutia) from 1853 to 2020. The following indicators of the epizootic process were used in the analysis: incidence rate, mortality and lethality. The object of the study comprised written reports of veterinarians of Yakutsk region to the governor about outbreaks of anthrax among domestic animals and people, quarterly and annual reporting data on the incidence rate and mortality of domestic animals, as well as statistical data on the number of farm animals in the specified period. The highest intensive manifestation of the epizootic process in cattle and horses during the study period was noted in the period until the 40s of the XX century. From the mid-forties, incidence and mortality rates were dynamically declining. The epizootic process of reindeer was characterized by an increase until the end of the 40s (1949), whereas from the 50s to the end of the 70s there was a decrease in the incidence and mortality rates. From 1980 to 1986, another increase in the epizootic process was recorded in the reindeer husbandry, followed by a decrease. Lethality of cattle ranging from 5 to 70% occurred in the period of 1946-1976, horses – in 1945-1993, deer – in 1949-1993. In other adverse years, starting from the official registration of anthrax to the mid-40s (1944-1946), it reached 100%. Overall, intensive manifestation of the epizootic process of anthrax dynamically decreased in the second half of the study period, with the exception of reindeer, in which it increased in 1980–1986 with a subsequent decrease.
