FIG 6.

Effect of isolation source on V. vulnificus attachment to chitin. The attachment efficiencies of two clinically isolated C-genotype strains (MO6-24 and CMCP6), two environmentally isolated E-genotype strains (JY1701 and JY1305), and two E-genotype strains isolated from wound infections (E64MW and LSU1657) are shown. Error bars represent the standard errors of the means from three replicates per strain. Clinical isolates (C-clinical and E-wound) attach to chitin significantly less than environmentally isolated E-genotype (E-environ) strains. Different letters indicate statistically significant differences (one-way ANOVA, P = 0.0002).
