Swarming motility assay. A swarming motility assay was performed using E. coli strains W, Crooks, K-12 (MG1655), K-12 (RP437), and B. B was negative; K-12 (MG1655) showed very minimal swarming, while K-12 (RP437), Crooks and W were positive. Assays were performed in triplicate at 25°C and at 37°C; results were similar at both temperatures (figure shows representative results from 25°C incubation).
