[Characterization of the katG, inhA, ahpC, kasA, and oxyR gene mutations in isoniazid-resistant and susceptible strain of Mycobacterium tuberculosis by automated DNA sequencing].

Abstract excerpt

OBJECTIVE: To study the characteristics of katG, inhA, ahpC, kasA, and oxyR gene mutations in isoniazid-resistant clinical isolates of Mycobacterium tuberculosis. METHODS: A total of 101 isoniazid-resistant and 43 susceptible strains of Mycobacterium tuberculosis were analyzed by PCR and sequence analysis of their katG, inhA, ahpC, kasA, and oxyR genes. RESULTS: (1) Sequencing of katG from 101 INH-resistant...
