FIG. 4.

Percent survival of C-genotype (solid bars) and E-genotype (open bars) strains of V. vulnificus incubated in artificial estuarine water and then removed and exposed to human serum for 1 h. Each bar represents the average survival in CFU for the five strains tested of each genotype. Results are relative to initial inoculum (control), which represent cells grown in modified HI (1,464 mosM) prior to microcosm inoculation and serum exposure. Asterisks denote significance based on results of two-way ANOVA with Bonferroni posttests (**, P < 0.01; ***, P < 0.001).
