Evaluation of a PCR-based universal heteroduplex generator assay as a tool for rapid detection of multidrug-resistant Mycobacterium tuberculosis in Peru

J Clin Microbiol. 2003 Dec;41(12):5774-7. doi: 10.1128/jcm.41.12.5774-5777.2003.


Multidrug-resistant tuberculosis is an increasing health problem worldwide, especially in developing countries. The PCR-UHG-Rif assay, which detects mutations within the rpoB gene associated with rifampin resistance, was evaluated for its ability and reliability to detect and identify drug-resistant Mycobacterium tuberculosis in a developing country where tuberculosis is highly endemic.
