Sub-MIC vancomycin promotes S. aureus planktonic growth (A) MRSA JE2 vancomycin E-test strip MIC assay. White box indicates zoomed in area for (B) a greater bacteria accumulation occurs near the edge of E-test strip inhibitory area (C) MSSA Newman strain containing an EGFP fluorescent reporter demonstrating a brighter green fluorescent signal near the edge of the vancomycin inhibitory are a indicating more bacterial growth. Sub-MIC vancomycin promotes increased planktonic growth in (D) MRSA JE2 (E) MSSA Newman and (F) SH1000. N = 4 per treatment group. Error bars represent standard deviation. *p < 0.05, **p < 0.01.
