Tuberculocid activity of the some biotechnological disinfectants

Abstract

Purpose. To study the bactericidal properties of atypical mycobacteria and pathogens of tuberculosis of disinfection preparations of foreign and domestic production. Methods. The bactericidal properties of disinfectants were studied in relation to test cultures of mycobacterium mycobacterium fortuitum, M. bovis, M. avium. Disinfection preparations were used in the experiments: brilliant, bromozept 50, FAG, DZPT-2. Experiments were conducted in accordance with the guidelines [2]. Results Experiments were carried out on cultures of M. bovis and M. avium tuberculosis pathogens on test objects (batiste, tree, tile, metal, glass) taking into account biological load. Conclusions It has been established that DZPT-2 preparations at a concentration of 2% for DR under exposure of 5 hours and FAG at a concentration of 2% at exposure of 24 hours disinfect all test objects contaminated by M. bovis and M. avium with a probability of 99%. The results of the culture study are confirmed by conducting a biological study of the bactericidal properties of the drugs.
