FIG 5.

Swarming motility assays performed in LB medium solidified with 0.6 and 1.0% agar. Swarming motility plates were inoculated with B. thuringiensis serovar israelensis strain GBJ002 and derivative lysogenic strains GBJ002/GIL01 and GBJ002/GIL16. (a) Mean values for swarming motility diameters in 0.6 and 1.0% agar at 24, 48, and 72 h. Error bars indicate standard deviation values from 9 measurements from 3 independent experiments. Means with different letters (A, B, C) indicate significant differences among the data for each experimental setup (Tukey's test, P < 0.05). (b) Bacterial swarming motility at 72 h of incubation. Similar observations were made in 3 independent experiments.
