Abstract

Enterococcus faecium BM4165 and BM4178, isolated from immunocompromised patients, one treated with vancomycin, were inducibly resistant to high levels of the glycopeptide antibiotics vancomycin and teicoplanin but susceptible to the new lipopeptide daptomycin (LY146032). Strain BM4165 was also resistant to macrolidelincosamide-streptogramin B-type (MLS) antibiotics. The genes conferring resistance to glycopeptides and to MLS antibiotics in strain BM4165 were carried on plasmids pIP819 and pIP821, respectively; pIP819 also carried genes that encoded resistance to MLS antibiotics. The two plasmids, which were distinct although related, were self-transferable to other E. faecium strains. Plasmid pIP819 could also conjugate to E. faecalis, Streptococcus sanguis, S. pyogenes, S. lactis, and Listeria monocytogenes, in which it conferred inducible glycopeptide resistance, but not to S. aureus. Glycopeptide-inactivating activity was not detected, and the biochemical mechanism of resistance remains unknown. Based on this first report of transferable resistance to glycopeptides, we anticipate dissemination of resistance to these antibiotics in gram-positive cocci and bacilli in which it can be phenotypically expressed.

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.
