Two Serologically Different Groups among the True Cholera Vibrios

Abstract

SUMMARYBy careful investigation of the somatic antigens of the true cholera vibrios —the strains containing O factor I according to Gardner's grouping (1935)— it was found, as did Scholtens (1933), that the cholera vibrios may be divided into two serological groups: one containing the antigenic factor A and the other the antigenic factors AB.This finding may be of importance in epidemiological investigations and in the preparation of vaccines.
