[Species category of Mycobacteria isolated from cattle and environmental objects].
The results of testing the slaughtered cattle material and environment objects for the presence of Mycobacteria are presented. During 1984-1988 with a stable excretion of pathogenic Mycobacteria, the quantity of the isolated atypical Mycobacteria tended to increase. In 1984 the atypical Mycobacteria made up 24.1% of the cultures isolated from cattle (pathogenic ones being 75.9%); in 1985, 29.0%; in 1986, 31.4%; in 1987, 46.0% and in 1988, 55.8%. For the above period M. bovis amounted to an average of 98.8% with annual fluctuations between 96.65 and 99.1%. During the last 5 years M. tuberculosis cultures ranged from 0.9 to 3.3% (1.92% on the average). M. avium was isolated from cattle in 22 cases out of 212 samples of the examined material (10.3%). As a result of testing of 2397 samples of the environment objects taken from 34 farms, 391 (16.3%) atypical Mycobacteria were isolated. It is necessary to continue, with regard to environmental conditions, the study of animal responses and atypical Mycobacterium carriage in different areas of the country.
