Random amplified polymorphic DNA analysis of Mycobacterium tuberculosis isolates resistant to Isoniazid in Indonesia

摘要

Background: M. tuberculosisis the most important etiological factor of tuberculosis. One of the factors that make TB hard to eradicate is the emergence of M. tuberculosisdrug resistance. Drug resistance in M. tuberculosisis attributed primarily to the accumulation of mutations in the drug target gene. Objectives: to analyze profile of Random Amplified Polymorphic DNA (RAPD) in M. tuberculosisisolates resistant to Isoniazid and found RAPD marker. Methods: seven Isoniazid resistant isolate of M. tuberculosisfrom Ma kassar, Indonesia strain were analyzed by RAPD method using primers OPN 02, OPN 09, OPN 20, BG 65, N 9, that amplification fragment DNA than as molecular marker. Results: The results of the present study showed high degree of polymerphism in theM.tuberculosisstrains in the population, and found that specific DNA fragment at Isoniazid resistant isolates using primer N 9 is 1450 bp as a marker. Conclusion: This study gives information about RAPD marker of M. tuberculosis strain to Isoniazid resistant.
