Subdivision of V. cholerae 01 into toxins on the basis of the whole complex of signs characteristic of this species does not make it possible to judge on their epidemic importance and to use the data on identification of V. cholerae for solving practical problems. Classification of V. cholerae by their capacity for producing toxin (choleragen and hemolysin of type 1, subtype beta) removes these difficulties.
