Production and characterization of a novel monoclonal antibody against Vibrio parahaemolyticus F(0)F(1) ATP synthase's delta subunit and its application for rapid identification of the pathogen.We raised monoclonal antibodies (MAbs) against Vibrio parahaemolyticus cell extracts. One of the MAbs, designated MAb-VP34, reacted in enzyme-linked immunosorbent assays (ELISAs) with 140 V. parahaemolyticus strains, regardless of serotype or origin. MAb-VP34 did not detectably react with 96 strains belonging to 27 other Vibrio species (except for Vibrio natriegens) or with 29 non-Vibrio species. These results show that MAb-VP34 is highly specific for V. parahaemolyticus. Western blotting and ma ...201222056232
