In vitro effects of some chemotherapeutic agents on mycobacteria. 1967

A L Olitzki, and D Godinger, and M Israeli, and A Honigman

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.

D009161 Mycobacterium A genus of gram-positive, aerobic bacteria. Most species are free-living in soil and water, but the major habitat for some is the diseased tissue of warm-blooded hosts. Mycobacteria
D009166 Mycobacterium leprae A species of gram-positive, aerobic bacteria that causes LEPROSY in man. Its organisms are generally arranged in clumps, rounded masses, or in groups of bacilli side by side.
D009169 Mycobacterium tuberculosis A species of gram-positive, aerobic bacteria that produces TUBERCULOSIS in humans, other primates, CATTLE; DOGS; and some other animals which have contact with humans. Growth tends to be in serpentine, cordlike masses in which the bacilli show a parallel orientation. Mycobacterium tuberculosis H37Rv
D009675 Novobiocin An antibiotic compound derived from Streptomyces niveus. It has a chemical structure similar to coumarin. Novobiocin binds to DNA gyrase, and blocks adenosine triphosphatase (ATPase) activity.
