FIG 6.

Effect of incubation temperature on attachment of C- and E-genotype strains to chitin. Depicted is attachment of two C-genotype strains (CMCP6 and M06-24) and two E-genotype strains (ENV1 and JY1305) incubated with chitin at room temperature (20°C) or the human physiological temperature (37°C). Error bars represent the standard errors of the means for two replicates of two strains. Different letters indicate statistically significant differences determined by using one-way ANOVA. Increasing the incubation temperature from 20°C to 37°C resulted in a significant increase in attachment for C-genotype strains and a significant decrease in attachment for E-genotype strains.
