Fig. 1From: Influence of PhoPQ and PmrAB two component system alternations on colistin resistance from non-mcr colistin resistant clinical E. Coli strainsThe mRNA expression levels of pmrD/phoP (A) and pmrK/pmrB/pmrA (B) in TSAREC02 and TSAREC02 WT-mgrB revertants. Values on the y axis are relative expression levels (fold change) normalized against levels in the colistin susceptible strain MG1655. * Significant differences compared to those in TSAREC02 (Student’s t-test, p < 0.05)Back to article page
