Abstract

Partial sequencing of the hsp65 gene was used for the identification of rapidly growing mycobacteria (RGM). A 441-bp fragment (A. Telenti, F. Marchesi, M. Balz, F. Bally, E. Böttger, and T. Bodmer, J. Clin. Microbiol. 31:175–178, 1993) was amplified and sequenced by an automated fluorescence-based method involving capillary electrophoresis. Type strains of 10 RGM species were first studied. Each species had a unique nucleotide sequence, distinguishing it clearly from the other species. A panel of strains from the four main RGM species responsible for human infections, Mycobacterium abscessus , Mycobacterium chelonae , Mycobacterium fortuitum , and Mycobacterium peregrinum , was also studied. There were few sequence differences within each of these species (<2% of bases were different from the type strain sequence), and they had no effect on species assignment. hsp65 sequencing unambiguously differentiated M. chelonae and M. abscessus , two species difficult to identify by classical methods and 16S rRNA gene sequencing. The devised procedure is a rapid and reliable tool for the identification of RGM species.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
