Effect of some antitubercular drugs on the calmodulin content of Mycobacterium tuberculosis.

The effect of the antitubercular drugs isoniazid (10 μg/ml), ethambutol (10 μg/ml), rifampicin (0.5 μg/ml) and streptomycin (1 μg/ml) on the calmodulin like protein (CAMLP) content of Mycobacterium tuberculosis HR and M. tuberculosis HR was investigated. The drugs were added to actively growing cells at their mid log phase of growth (14 days) and after 12 more hours of incubation, CAMLP was estimated. In both the mycobacteria, all the four antitubercular drugs CAMLP. [ABSTRACT FROM AUTHOR]
