Comparison of tuberculosis epizootic tension with some parameters characterizing the epidemiological situation in areas with different incidence rates of cattle tuberculosis under present conditions showed their inverse correlation. It is suggested that with a drastic improvement of the epizootic situation, the cattle becomes an agent of natural immunization of inhabitants in poor districts, as evidenced not only by the lack of new cases of tuberculosis in human beings, but by an increase in cases with residual posttuberculous changes in the lung (14.1% of the stock breeders examined in the long poor tuberculosis area versus 3.7% in this infection-free area), as well as by high infection rates (74.2 versus 43.5%).
