Studies on toxinogenesis in Vibrio cholerae. II. An vitro test for enterotoxin production.
An Elek test for enterotoxin-producing strains of Vibrio cholerae is described. Thirty-five out of 37 strains of classical V. cholerae produced positive reactions, but only 1 of 69 E1 Tor vibrio strains was reactive. Tox(-) mutants of V. cholerae were also unreactive in the Elek test.
