In vitro effects of some chemotherapeutic agents on mycobacteria.

Examination of the bactericidal and bacteriostatic effects of nine antibiotics on atypical mycobacteria revealed that streptovaricin complex and streptovaricin C exerted bactericidal effects on several strains in concentrations lower than 1.0 mug/ml. An exposure to the drug for 48 hr at 37 C was necessary to effect a complete inactivation of more than 99.9% of the exposed microorganisms. The appearance of strepto-varicin-resistant mutants was observed. However, these mutants were unstable, and reversion to streptovaricin susceptibility occurred. Celesticetin salicylate, added in a concentration of 100.0 mug/ml to the medium of Olitzki and Gershon inoculated with Mycobacterium leprae, effected a complete change of the uniformly stained mycobacteria to bipolarity, which indicates the devitalization of this microorganism.
