[Drug sensitivity in Mycobacterium tuberculosis versus its viability, cytotoxicity, genotype, and the course of the process in patients with pulmonary tuberculosis].

The authors studied drug sensitivity, mutations in the katG, in-hA, alpC, rpoB genes, virulence via the cytotoxicity test on THP-1 cells, and the viability and genetic affiliation of 53 clinical M. tuberculosis isolates versus data on the form and dynamics of a process. Sensitive and resistant strains did not significantly differ in viability and cytotoxicity.
