Abstract
Vibrio parahaemolyticus is a gram-negative bacterium which acts as a causative agent for food poisoning. Studies with respect to specific extracellular proteins of V. parahaemolyticus would be useful for the development of specific detection methods against V. parahaemolyticus. In our present study, outer membrane proteins (OMPs) of V. parahaemolyticus were obtained from insoluble traction of 1% sarkosyl treated-cell wall materials. SDS-PAGE analysis showed the presence of several conserved outer membrane proteins among five strains of V. parahaemolyticus, and three bands were identified as V. parahaemolyticus OMPs through MALDI-TOF analysis. Polyclonal antibodies enriched with anti-OmpU were obtained from immunized rabbits. The antibodies against these proteins may be useful for the development of detection methods for V. parahaemolyticus.
