FIG. 1.

Survival of clinical (solid bars) and environmental (open bars) genotypes of V. vulnificus exposed to normal human serum (A) or complement-inactivated human serum (B). Each bar represents the average survival in CFU for the five strains tested of each genotype. Control columns represent cells grown in HI prior to serum exposure. Asterisks denote significant differences between genotypes at each time interval based on results of two-way ANOVA with Bonferroni posttests (*, P < 0.05; **, P < 0.01).
