FIG 2.

Expression of genes involved in capsular polysaccharide production by two E-genotypes (JY1701 and JY1305) relative to two C-genotypes (CMCP6 and MO6-24) of V. vulnificus under aerobic (A) and anaerobic (B) conditions. Error bars represent the standard errors of five biological replicates, comprising three technical replicates averaged for each strain (two of each genotype). Asterisks represent statistically significant differences (**, P < 0.01; ****, P < 0.0001) between E-genotypes relative to C-genotypes of each gene transcript, based on the nonparametric Mann-Whitney test with corrected P value utilizing the Bonferroni calculation. Anaerobically, E-genotypes express significantly higher levels of wza, wzb, and wzc than C-genotypes; under aerobic conditions, significant differences were observed only for wzb and wzc.
