Balakrish Nair Translational Health Science and Technology Institute Thandavarayan Ramamurthy ational Institute of Cholera and Enteric Diseases, Kolkata 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. No potential conflict of interest relevant to this article was reported.

Bhattacharya K. Rajendran Gopinath Balakrish Nair Thandavarayan Ramamurthy We identified 131 strains of Vibrio fluvialis among 400 nonagglutinating Vibrio spp. isolated from patients with diarrhea in Kolkata, India. For 43 patients, V. fluvialis was the sole pathogen identified. Most strains harbored genes encoding hemolysin and metalloprotease; this finding may contribute to understanding of the pathogenicity of V. fluvialis. No potential conflict of interest relevant to this article was reported.
