Multiple Regulators Control Capsular Polysaccharide Production in Vibrio parahaemolyticus

Abstract excerpt

Vibrio parahaemolyticus, a biofouling marine bacterium and human pathogen, undergoes phase variation displaying translucent (TR) and opaque (OP) colony morphologies. Prior studies demonstrated that OP colonies produce more capsular polysaccharide (CPS) than TR colonies and that opacity is controlled by the Vibrio harveyi LuxR-type transcriptional activator OpaR. CPS has also been shown to be regulated by the...
