Vibrio parahaemolyticus is the leading cause of seafood-associated bacterial gastroenteritis and is a moderately halophilic, salt-requiring bacterium. Global gene expression profiles of V. parahaemolyticus grown under 2% and 0.66% NaCl were compared to define the low-salt stimulon. The ectABC-lysC operon for synthesis of the compatible solute ectoine, as well as three compatible solute transport systems, namely ProU (glycine betaine), OpuD1 (glycine betaine) and Pot2 (spermidine), was up-regulated under 2% NaCl relative to 0.66% NaCl. The 2% NaCl condition favored the inducible expression of OmpW, OmpN and OmpA2, while repressed the expression of OmpA1, OmpU and VP1008. These results indicated that, to master the hyperosmotic stress of saline environments, V. parahaemolyticus might not only accumulate osmoprotectants through uptake or endogenous synthesis of compatible solutes, but also remodel its profiles of outer membrane protein to restore its cell membrane. The above differentially regulated genes will provide novel candidates for the further investigation of the molecular mechanisms of osmoadaptation in V. parahaemolyticus.
