Abstract
A sample of 124 isoniazid (INH)-resistant and 88 susceptible strains o f Mycobacterium tuberculosis complex from south, central, and west Afr ica was analyzed by direct sequence analysis and PCR-restriction fragm ent length polymorphism analysis of their catalase-peroxidase (katG) g enes. Point mutations at codon 315 were found in the genomes of 64% of INH-resistant strains, but no complete deletions were identified. Mut ations at codon 463 were independent of INH resistance and were linked to the geographic origins of the strains.
