| Abstract: | Reaction to intradermal injection of tuberculin from Mycobacteria tuberculosis of the avian type proved to be negative in all the 505 students examined who never came in contact with fowl farms. Of 738 local residents it was found to be positive in 23.8% and of 320 workers of fowl farms--in 54.5% of cases. In response to the injection of Koch tuberculin and PPD-L the number of positive reactions in all the mentioned groups constituted 69-80%. A conclusion was drawn on the epidemiological danger of Mycobacteria of the avian type for the workers of fowl farms and, to a certain degree, for the surrounding population. |
