The ablation of the HP0256 gene impairs motility in H. pylori that may be restored by complementation, when hp0256 is put under the control of the promoter of flaA. Motility plate assay were performed four times. A. CCUG17874 wild-type strain; B. CCUG17874-hp0256KO; C. P79 wild-type strain; D. P79-hp0256KO; E. P79-hp0256KO complemented with pIR0601; F. P79-hp0256KO with empty vector (control).
