摘要
Enterococci and staphylococci have evolved different resistance mechanisms to counteract glycopeptide antibiotics. High- and low-level resistance in enterococci results from new pathways of peptidoglycan biosynthesis together with elimination of peptidoglycan precursors with high affinity for glycopeptides. In staphylococci the main mechanism appears to involve sequestration of the antibiotic in the outer layers of the cell wall before it reaches the vital target sites.
