Received 4 January 2005; accepted 30 June 2005.
Abstract
A fatal infection with temporal relation to 2 other febrile infections caused by Vibrio cholerae non-O1, non-O139 (NCV) occurred in Finland in 2003. All infections were associated with contact with seawater. The patient who died had also eaten home-salted whitefish, tested positive for NCV, preceding his symptoms. All patients had compromising factors, and all strains were distinguishable by pulsed-field gel electrophoresis and negative for the ctx gene. These 3 cases illustrate that, despite being uncommon in Finland, NCVs can cause clinically significant and even fatal infections.
