The intrinsic macrolide resistome of Escherichia coli.

PMID 38940570 · 2024

The study identified several genes involved in intrinsic macrolide resistance in E. coli, including surA, waaG, acrA, acrB, tolC, lptC, bamB, lpp, tolA, tolB, tolR, waaQ, gmhB, galU, waaP, lapC, prc, nlpI, hrpA, and pgm. These genes are associated with outer membrane integrity, efflux pumps, LPS biosynthesis, and peptidoglycan metabolism.
