Abstract

Two strains of cholera toxin (CT) gene-positive Vibrio cholerae O1, Ogawa, isolated from patients with diarrhoea and the hypertoxigenic V. cholerae O1, Inaba (569B), were found to produce the new cholera toxin that has earlier been demonstrated to be elaborated by CT gene-negative human and environmental isolates of V. cholerae O1. The CT gene-positive strains produce the new cholera toxin simultaneously with CT, indicating that they contain the gene coding for the new cholera toxin in addition to that of CT.
