For the last 5 years, the examination of the farms in the Ukrainian SSR revealed the following distribution of Mycobacterium cultures isolated from cattle: M. bovis, 50.5%, M. hominis, 0.4%; M. avium, 1.8%; and atypical bacilli, 47.3%. In 31% of the farms considered to be safe enough in relation to tuberculosis, tuberculin-sensitive cattle was identified, thus totalling 47.3% of these farms where as many as 15 types of atypical Mycobacteria were shown to cause its sensitization. Photochromogenic Myco. cultures were not isolated either from the cattle or from the environmental objects. Single cases of tuberculous cattle infected by the human hosts were found as a consequence of the violation of the rules adopted in the farms to prevent this disease. Bovine tuberculosis-infected people were not detected. |
