The induced β-lactam resistance of S. sciuri caused by the thickened cell wall. (A) KEGG enrichment scatter map of the upregulated differentially expressed gene in NWAF26R compared with NWAF26. (B) The expression of genes related to wall teichoic acid (WTA) synthesis pathway was upregulated in NWAF26R and highlighted with red color, the number represented the fold changes of upregulation. (C) Transmission electron microscopy (TEM) analysis of NWAF26 and its derivations at the stationary phase. NWAF26 R-R10 represents the 10th generation isolate induced from NWAF26 R without oxacillin. The standard ruler is 100 nm.
