Fig. 2

Relative mRNA expression levels of pmrB gene in both the parental isolates and their colistin-resistant subpopulations (COL-RP). Expression was measured as a relative quantity by quantitative real-time polymerase chain reaction (qRT-PCR) using reference gene rpoB. *p < 0.05; **p < 0.01; ***p < 0.001
