Abstract

The bactericidal, cell membrane–targeting lipopeptide antibiotic daptomycin (DAP) is an important agent in treating invasive Staphylococcus aureus infections. However, there have been numerous recent reports of development of daptomycin resistance (DAP‐R) during therapy with this agent. The mechanisms of DAP‐R in S. aureus appear to be quite diverse. DAP‐R strains often exhibit progressive accumulation of single nucleotide polymorphisms in the multipeptide resistance factor gene (mprF) and the yycFG components of the yycFGHI operon. Both loci are involved in key cell membrane (CM) events, with mprF being responsible for the synthesis and outer CM translocation of the positively charged phospholipid, lysyl‐phosphotidylglycerol (L‐PG), while the yyc operon is involved in the generalized response to stressors such as antimicrobials. In addition, other perturbations of the CM have been identified in DAP‐R strains, including extremes in CM order, resistance to CM depolarization and permeabilization, and reduced surface binding of DAP. Moreover, modifications of the cell wall (CW) appear to also contribute to DAP‐R, including enhanced expression of the dlt operon (involved in d‐alanylation of CW teichoic acids) and progressive CW thickening.

  • A homolog of LiaFSR (VraTSR) seems to also contribute to the DAP-R phenotype mediated by changes in MprF in S. aureus.

    “Of interest, a homolog of LiaFSR (VraTSR) seems to also contribute to the DAP-R phenotype mediated by changes in MprF in S. aureus (97).”

  • YycFG (WalKR), an essential two-component regulatory system implicated in cell-wall synthesis and homeostasis, has been found to be important to DAP-R both in enterococci and S. aureus.

    “For example, YycFG (WalKR), an essential two-component regulatory system that has been implicated in cell-wall synthesis and homeostasis, has been found to be important to DAP-R both in enterococci and S. aureus (96, 97).”

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.
