Fig. 4

The B. pseudomallei bprS and bprR mutants display reduced motility. Swarming motility was measured on agar plates grown at 37 °C for 18 h. Panel a, selected images of motility plates and Panel b, quantification of the motility data. Strains are B. pseudomallei wild-type (WT), directed bprS mutant (bprS), bprS transposon mutant (bprS::Tn5), bprR mutant (bprR), bprRS double mutant (bprRS), complemented bprS mutant (bprS(bprRS)), bprS mutant containing empty vector (bprS(pBHR1)) and a non-motile fliC mutant control (panel b only). Data are mean ± SEM. * = P < 0.01
