All the isolates of V vulnificus (n=234) were tested for the presence of the vvhA virulence gene using PCR, and 52 (21.8%) of the isolates tested positive for this gene (Fig.
vulnificus that were positive for the vvhA gene, only 51 isolates were typed using ERIC-PCR to find out the genetic relationship among the isolates.
vulnificus that tested positive for the vvhA gene were multi-drug resistant (Table 3).
In addition, this study is the first report of the presence of the vvhA gene in isolates of V.
