Resistance profiles and rpoB gene mutations of Mycobacterium tuberculosis isolates in Taiwan.
BACKGROUND/PURPOSE The rifampicin resistance of Mycobacterium tuberculosis is caused by mutations in the 81-base pair region of the rpoB gene encoding the β-subunit of RNA polymerase. Sequences of the rpoB gene of 68 isolates were analyzed to identify the mutations and to compare the mutations with their related susceptibilities. METHODS Susceptibility tests of 68 M. tuberculosis isolates, co...
متن کاملMutations in the RpoB Gene of Multidrug-Resistant Mycobacterium Tuberculosis Isolates from Semarang, Indonesia
ABSTRACTTuberculosis is an infectious disease which occurs widely in the world and becomes one of the top 10 causes of death worldwide. Mutations of the RpoB gene cause the resistance of Mycobacterium tuberculosis to rifampicin that contributes to the occurrence of MDR-TB. This study aimed to determine the pattern of rpoB gene polymorphisms in the MDR M. tuberculosis in Semarang, Indonesia. Mos...
متن کاملCharacterization of Mutations in the Rpob and Katg Gene of Mycobacterium Tuberculosis Isolates From Pasteur Institute of Tehran
Objective: The Rifampicin resistance and susceptibility of Mycobacterium tuberculosis are caused by mutations in the 81-base pair region of the rpoB gene encoding the b-subunit of RNA polymerase. Methods: Isoniazid resistance of M. tuberculosis is related to mutations in inha , oxyR and ahpC genes which 30 to 90 percent of Isoniazid resistance is occurred in 3015 codons of kat...

متن کاملRifabutin Resistance Associated with Double Mutations in rpoB Gene in Mycobacterium tuberculosis Isolates
The objective of this study was to investigate the cross-resistance between rifampin (RIF) and rifabutin (RFB) among clinical Mycobacterium tuberculosis (MTB) isolates, and the correlations between specific rpoB mutations and the minimum inhibitory concentrations (MICs) of RIF and RFB. A total of 256 RIF-resistant isolates were included from the National Tuberculosis Clinical Laboratory in Chin...
