Vibrio parahaemolyticus enterocolitis in Bangladesh : report of an outbreak

Abstract

In March 1974 eight men in Chandpur, Bangladesh, experienced an illness characterized by severe abdominal cramps, nausea, vomiting and bloody diarrhea with onset 20 min to 9 h (median 2.5 h) after eating one of two fish dishes at a restaurant. Rectal cultures from all eight grew Kanagawa-positive strains of Vibrio parahaemolyticus (serotype O3K5) that were negative in the Sereny test for invasiveness and the Y-1 adrenal cell and infant mouse assays for enterotoxin production. The short incubation, severity of abdominal cramps and grossly bloody stools distinguish this illness from that usually associated with V. parahaemolyticus infection in the United States
