Incidence of non-specific tuberculin reactions in cattle in the Republic of Tatarstan in comparison with bovine tuberculosis epizootic situation

Abstract

This article presents the results of the analysis of the epizootic situation for bovine tuberculosis and indicators of the frequency of non-specific reactions of bovine to tuberculin in the Republic of Tatarstan in the period from 2010 to 2019. It was found that during the study period, the maximum number of primary tuberculosis-affected localities was registered in 2013, and since 2017, the territory of the Republic is still free of tuberculosis. On average, 2400 non-specific reactions are detected per year. There are also cartograms of the spread of tuberculosis and occurring of non-specific tuberculin reactions, which show that the main number of such reactions is registered geographically in the same zones where tuberculosis-affected localities are located.
