Abstract:
:Real-time isothermal nucleic acid sequence-based amplification (RT-NASBA) was applied to the detection of Mycoplasma pneumoniae. In vitro-generated M. pneumoniae RNA was used to assess the sensitivity of the assay. The 95% hit rate was 148 molecules of M. pneumoniae RNA in the amplification and 10(4) molecules of in vitro-generated RNA after nucleic acid extraction. The sensitivity of the RT-NASBA and the conventional NASBA assays corresponded to 5 color-changing units (CCU) of M. pneumoniae. In spiked throat swabs, nasopharyngeal aspirates, bronchoalveolar lavages, and sputum, the sensitivity of both NASBA assays corresponded to 5 to 50 CCU of M. pneumoniae. A total of 17 clinical specimens positive for M. pneumoniae by PCR were also positive by conventional NASBA, but one specimen was negative by RT-NASBA. These results indicate that the sensitivity of detection of M. pneumoniae by RT-NASBA in respiratory samples might be slightly reduced compared to that by conventional NASBA. However, the real-time assay is superior in speed and ease of handling.
