FIG. 7.

VopB2 and VopD2 are necessary for T3SS2-dependent enterotoxicity. The enterotoxic activities of V. parahaemolyticus mutant and complemented strains in rabbit ileal loops were examined. Fluid accumulation is the amount of fluid accumulated (in milliliters) per centimeter of ligated rabbit small intestine. The error bars indicate the standard deviations for the results of triplicate experiments. An asterisk indicates that the results are significantly different from the results obtained with the parental strain (P < 0.05).
