Genetic complementation of the motA(T551G) mutant isolate. (A) Motility of isolate 251/01 carrying pLVR10 (motA) or the empty vector in soft agar plates containing increasing concentrations of arabinose (in % [wt/vol]). For comparison, isolate 8/02 was included in the analysis. (B) Motility of isolates 8/02, 251/01, and motA-inactivated and recomplemented derivatives in soft agar plates. Means ± SEM are shown. **, significant difference compared to results for PT4 (P < 0.01).
