Vibrio cholerae non-O1, non-O139 serogroups and cholera-like diarrhea, Kolkata, India

Emerg Infect Dis. 2013 Mar;19(3):464-7. doi: 10.3201/eid1903.121156.

Abstract

We identified 281 Vibrio cholerae non-O1, non-O139 strains from patients with diarrhea in Kolkata, India. Cholera-like diarrhea was the major symptom (66.0%); some patients (20.3%) had severe dehydration. These strains lacked the ctxA gene but many had hlyA, rtxA, and rtxC genes. Pulsed-field gel electrophoresis showed no genetic link among strains.
