qRT-PCR-derived fold-change (FC) expression differences. Expression differences for the indicated genes derived from the comparison of strain PA20 with: 1) PA20ΔpchE, 2) PA20 pSE380::pchE, and 3) PA20 SMX-TM (PA20 exposed to 540/108 μg/L sulfamethoxazole/trimethoprim (SMX-TM)). (A) Genes of proven adhesins and global adhesin regulators. (B) Flagellar motility-associated genes. The mean FC ± SD of three trials of qRT-PCR for each indicated gene is shown.
