Research findings from S. Chakravorty et al update understanding of tuberculosis
October 7th, 2008
"Rifampin resistance is a key prognostic marker for treatment success in tuberculosis patients. Recently, Wang et al. demonstrated that Rv2629 A191C mutations were present in 99.1% of rifampin-resistant and 0% of rifampin-susceptible clinical Mycobacterium tuberculosis isolates and that overexpression of the Rv2629 191C allele in Mycobacterium smegmatis produced an eightfold increase in rifampin resistance," scientists in the United States report. "These results suggested that Rv2629 could be a cause of rifampin resistance and a valuable target for rifampin resistance detection assays. We developed a molecular-beacon assay to study the association between Rv2629 191...
