Fig 3. Swimming motility of B. pseudomallei T24 transposon mutants.

Overnight cultures of the wild type and transposon mutants were used to inoculate 0.3% agar plates, incubated at 37°C, and swim zone diameter was measured at 24 h. Asterisks indicate a significant difference as obtained with the Mann-Whitney test utilizing the Bonferroni correction (p = 0.001) to account for multiple comparisons (n = 37). All mutants were tested at least twice in triplicate. Error bars indicate standard error of the mean.
