[Severe gastroenteritis after domestic infection with Vibrio cholerae non-O1]

Vibrio cholerae non-O1 has previously been isolated only occasionally in Norway from patients infected abroad. This report describes the clinical course in two patients who were domestically infected with V. cholerae non-O1. In one case, contaminated seafood, i.e. crab, was the probable source of infection. Both patients displayed a cholera-like type of illness, with severe diarrhoea and electrolyte disturbances. It is recommended that Norwegian laboratories be prepared to isolate vibrios also in domestically infected cases when watery diarrhoea is present.
