Characterization of rpoB mutations in rifampin-resistant clinical isolates of Mycobacterium tuberculosis from Turkey by DNA sequencing and line probe assay.
Mutations in an 81-bp region of the rpoB gene associated with rifampin resistance were studied in 41 rifampin-resistant clinical strains of Mycobacterium tuberculosis isolated in Turkey. Fourteen different rpoB alleles, three of which had not been reported before, were found. A reverse hybridization-based line probe assay (the Inno-LiPA Rif.TB test) for rapid detection of the mutations was eval...
متن کاملCharacterization of rpoB mutations in rifampin-resistant clinical Mycobacterium tuberculosis isolates from Greece.
There is a geographic distribution of Mycobacterium tuberculosis strains with various rpoB gene mutations that account for rifampin resistance. We studied 17 rifampin-resistant clinical isolates from patients in Greece to identify rpoB mutations. The aim of our study was the evaluation of a commercially available line probe assay kit (INNO-LiPA Rif. TB) to detect rpoB mutations and rifampin res...
متن کاملCharacterization of rpoB mutations by line probe assay in rifampicin-resistant mycobacterium tuberculosis clinical isolates from the aegean region in Turkey.
The nature and frequency of mutations in the rpoB gene of rifampicin (RIF)-resistant Mycobacterium tuberculosis clinical isolates vary considerably according to the geographical location, and very little information is available regarding specific mutational patterns in our country. The main objective of this study was to determine the frequency of mutations in the hypervariable region of the r...
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 کاملrpoB Gene mutations and molecular characterization of rifampin-resistant Mycobacterium tuberculosis isolates from Shandong Province, China.
Sixty rifampin (RIF)-resistant and 75 RIF-susceptible Mycobacterium tuberculosis isolates from Shandong Province, China, were analyzed for rpoB gene mutations and genotyped. Mycobacterial interspersed repetitive unit (MIRU) genotype 223325173533 was overrepresented among RIF-resistant isolates. MIRU combined with IS6110 restriction fragment length polymorphism analysis as the second-line genoty...
