FIG 4.

Effect of N-acetylglucosamine (GlcNAc) on V. vulnificus attachment to chitin. Depicted is the attachment efficiencies of two C-genotype (CMCP6 and M06-24) and two E-genotype (ENV1 and JY1305) strains incubated with chitin in the presence or absence of 125 mg/ml GlcNAc. Error bars represent the standard errors of the means for two replicates of two strains. Incubation with GlcNAc resulted in a significant decrease in attachment for strains of both genotypes. Different letters indicate statistically significant differences determined by using one-way ANOVA.
