In Situ Gene Expression by Vibrio vulnificus

Abstract
Strains of Vibrio vulnificus incubated in situ in natural estuarine waters during warm months continued to express katG (periplasmic catalase), rpoS (stress sigma factor), tufA (elongation factor), wza, and wzb (capsule synthesis). vvhA (hemolysin) was differentially expressed between environmental and clinical isolates. These results paralleled our in vitro findings.
