FIGURE 2.
Overexpression of AcrAB and OqxAB in clinical K. pneumoniae 1678 isolate. The expression levels of AcrA/B (A), OqxA/B (B), and related transcriptional regulators was determined by qRT-PCR. The K. pneumoniae ATCC13883 is used as the reference strain (expression = 1.0). The data represent the mean standard deviation for three independent biological replicates. Differences between different strains, regarding related gene expression, were statistically analyzed using a two-tailed Student’s t-test with Bonferroni correction. ****p < 0.0001.
