SUMMARY Esterases of strains of Vibrio cholerae, V. parahaemolyticus , noncholera and marine vibrios were examined by electrophoresis in starch gels. The enzyme patterns indicated a relative homogeneity occurring amongst the strains. No separation of the genus Vibrio into subgroups corresponding to the El Tor, classical cholera or noncholera groupings was noted. Overall deoxyribonucleic acid base composition for the Vibrio spp. ranged from 44‐49 mol% guanine + cytosine, with the marine vibrios lowest in guanine + cytosine content. Enzyme patterns for cholera vibrios isolated during very recent epidemics were identical to those of established laboratory strains, suggesting a marked stability of the esterase system for V. cholerae.
