Abstract

Background: Indonesia have many different geographic areas which could be various on the variant strains of Mycobacterium tuberculosis. The gyrB gene codes GyrB protein as sub unit compound of Gyrase enzyme that functioning in multiplication of bacteria. Detection of gyrB gene could be a marker of active multiplication of viable bacteria in the specimen from patients; and some of the DNA sequence regions were conserved and specific in the strain of Mycobacterium tuberculosis that would be a marker for identification. This research aims to analyze the sequence of gyrB gene of Mycobacterium tuberculosis clinical isolates from sputum of pulmonary TB patients in Indonesia, and determine the specific region. Method: Mycobacterium tuberculosis clinical isolates have been collected from sputum of the patients with pulmonary TB that live in some area in Indonesia. Isolation and identification of Mycobacterium tuberculosis clinical isolates using standard culture method; sequence analysis using PCR-direct sequencing of the part bases region of gyrB. Results: this study revealed that nucleotide sequence on a fragment 764 bases of gyrB gene Mycobacterium tuberculosis strains among clinical isolates almost identically to a wild type strain Mycobacterium tuberculosis H37Rv and subspecies member of Mycobacterium tuberculosis complex (MTBC), with a little difference of SNPs; there are many difference nucleotide sequence with MOTT and Gram positive or negative bacteria, except Corynebacterium diphtheriae identically with MTBC. Conclusion: the gyrB sequence in Mycobacterium tuberculosis strains among these clinical isolates from sputum of pulmonary TB patients in Indonesia have the conserved specific DNA region that almost identically with wild type strain H37Rv and MTBC.
