New Mycobacteroides abscessus subsp. massiliense strains with recombinant hsp65 gene laterally transferred from Mycobacteroides abscessus subsp. abscessus: Potential for misidentification of M. abscessus strains with the hsp65-based method.

ABSTRACT: It has been reported that lateral gene transfer (LGT) events among Mycobacteroides abscessus strains are prevalent. The hsp65 gene, a chronometer gene for bacterial phylogenetic analysis, is resistant to LGT events, particularly among mycobacterial strains, rendering the hsp65-targeting method the most widely used method for mycobacterial detection. To determine the prevalence of M. abscessus strains that are subject to hsp65 LGT, we applied rpoB typing to 100 clinically isolated Korean strains of M. abscessus that had been identified by hsp65 sequence analysis. The analysis indicated the presence of 2 rough strains, showing a discrepancy between the 2 typing methods. MLST analysis based on the partial sequencing of seven housekeeping genes, erm(41) PCR and further hsp65 PCR-restriction en
