Abstract
The present invention provides primers which can be used for M. tuberculosis complex-specific detection of .alpha.-antigen DNA in a diagnostic assay performed on clinical specimens or in a culture-confirmation assay following growth of the organism in vitro. These primers and probes can also be employed in a reverse transcriptase-mediated amplification system for M. tuberculosis complex .alpha.-antigen mRNA. Such an assay provides a means by which to determine the viability of M. tuberculosis complex organisms either in clinical specimens or when grown in culture. The specific DNA or mRNA target region can be amplified using SDA, PCR, LCR, Nucleic Acid Sequence Based Amplification (NASBA), Self-sustained Sequence Replication (3SR) or Q.beta. Replicase-mediated systems. Also described are methods for the detection of the products of amplification with a radiolabeled probe by chemiluminescent assay or fluorescence polarization analysis.
