Characterization of Molecular Evolution in Multi-Drug Resistant of Mycobacterium tuberculosis by rpoB Gene in Patient with Active Pulmonary Tuberculosis from Iranian Isolates.

This is the first genetic biodiversity study of Mycobacterium tuberculosis in Iran. Thus, we investigated the genetic patterns of strains isolated in the first survey of anti-tuberculosis drug-resistance by rpoB gene as part of the Global Project of Anti-tuberculosis Drug Resistance Surveillance (IAU, Iran). A 411-bp fragment of the rpoB gene, containing the sequence of the 81-bp rpoB fragment, was amplified by PCR and the rpoB gene fragments of tuberculosis strains were sequenced using the Amersham auto sequencer.
