Abstract
A method is provided for detecting M. tuberculosis or mutants thereof, particularly rifampin-resistant MTB, in a biological sample comprising: isolating DNA from the biological sample; amplifying the isolated DNA under hybridizing conditions with a primer set that targets portions of the gene encoding rpoB; wherein the pimer set comprises at least one primer that hybridizes under hybridizing conditions to at least one signature nucleotide for M. tuberculosis; and isolating and sequencing the amplified DNA to determine the presence or absence of M. tuberculosis or mutants thereof.
