Immunological detection of the Kanagawa phenomenon of Vibrio parahaemolyticus on modified selective media

Abstract

Selective media for Vibrio parahaemolyticus, BTB-Teepol agar and modified arabinose-ammonium sulfate-cholate agar, were modified for use in immunological detection of the thermostable direct hemolysin produced by this organism. The modified BTB-Teepol agar and modified arabinose-ammonium sulfate-cholate agar were both found to be useful for the modified Elek test and immunohalo test with antiserum (or immunoglobulin G) against the thermostable direct hemolysin. With these modified media it is possible to isolate V. parahaemolyticus and identify the Kanagawa phenomenon on a single plate and thus save time in obtaining results.
