Motility of wild type and lrhA mutant E. coli UTI89 and APEC1. Motility of the E. coli strains was investigated by transferring mutant and wild type colonies onto the same plate containing LB with 0.3% agar, with a sterile toothpick. After incubation, the diameter of the colonies was compared [12]. The motility of the lrhA mutants is much higher than the motility of the corresponding wild type strains.
