Comparative genomics reveals the correlations of stress response genes and bacteriophages in developing antibiotic resistance of Staphylococcus saprophyticus.

Research Article

PMID 38051037 · 2023

The study identifies several AMR genes in Staphylococcus saprophyticus, including mecA, blaZ, erm, erm(44)v, msr(A), and mph(C), which confer resistance to beta-lactams, macrolides, and lincosamides. The presence of these genes is associated with varying levels of resistance, and some genes, like mecA, are useful markers for predicting resistance to specific antibiotics.
