Abstract

A PCR assay that allows simultaneous detection of glycopeptide resistance genotypes and identification to the species level of clinically relevant enterococci (Enterococcus faecium, E. faecalis, E. gallinarum, and E. casseliflavus) was developed. This assay was based on specific amplification of internal fragments of genes encoding D-alanine:D-alanine ligases and related glycopeptide resistance proteins. The specificity of the assay was tested on 5 well-characterized glycopeptide-resistant strains and on 15 susceptible enterococcal type strains. Clinical isolates of enterococci that could not be identified to the species level by conventional methods were identified by the PCR test. This assay offers a specific and rapid alternative to antibiotic susceptibility tests, in particular for detection of low-level vancomycin resistance.

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.
