Antibiotics promote SCC excision via ccrC1. Primer pairs corresponding to the two sides of SCCmec (EGRT-F and EGRT-R) were used to determine the ratio of the SCC-excised genome. The arrowheads indicate values below the limit of detection (<2.5 × 10⁻¹¹). One copy of the gene tpi (triosephosphate isomerase gene) was used as a reference. The bars represent the averages of three independent measurements in three different cultures, and the error bars represent the standard error of the mean. OXA, oxacillin; TEC, teicoplanin; VAN, vancomycin; GEN, gentamicin; KAN, kanamycin; TET, tetracycline; SMX, sulfamethoxazole; CIP, ciprofloxacin; TMP, trimethoprim.
