Abstract excerpt
The catalase-peroxidase gene (katG) and a two-gene locus (inhA) containing mutations associated with resistance to isoniazid in Mycobacterium tuberculosis were sequenced in 34 resistant and 12 susceptible strains. Virtually all resistant organisms had amino acid changes in KatG or nucleotide substitutions upstream of inhA. A region of katG encoding two amino acids frequently altered in resistant strains (residues...
