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.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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 enzyme and polymorphism analysis (PRA) were conducted to identify the two strains. The MLST results showed that the two strains belong to M. abscessus subsp. massiliense and not to M. abscessus subsp. abscessus, as indicated by the rpoB-based analysis, suggesting that their hsp65 genes are subject to LGT from M. abscessus subsp. abscessus. Further analysis of these strains using the hsp65 PRA method indicated that these strains possess a PRA pattern identical to that of M. abscessus subsp. abscessus and distinct from that of M. abscessus subsp. massiliense. In conclusion, we identified two M. abscessus subsp. massiliense rough strains from Korean patients with hsp65 genes that might be laterally transferred from M. abscessus subsp. abscessus. To the best of our knowledge, this is the first demonstration of possible LGT events associated with the hsp65 gene in mycobacteria. Our results also suggest that there is the potential for misidentification when the hsp65-based protocol is used for mycobacterial identification.
