Abstract excerpt
The ahpC genes of 57 clinical isolates and one in vitro mutant of Mycobacterium tuberculosis were evaluated by nucleotide sequence analyses. Although compensatory ahpC promoter mutations were identified in 8 catalase-negative, katG-defective strains, the ahpC genes of 25 catalase-positive, isoniazid-resistant isolates and 25 drug-sensitive strains were not altered.
