A case of Plesiomonas shigelloides cellulitis and bacteraemia from northern Europe

Bacteremia caused by Plesiomonas shigelloides is a rare event, often associated with consumption of seafood and fresh or estuarine water in temperate or tropical climates. Most patients have showed underlying health disorders. Here we present a case of P. shigelloides septicaemia and cellulitis of the left hand associated with fish handling in Northern Sweden (65 degrees latitude north). The patient, who suffered from multiple myeloma, recovered uneventfully after initial treatment with intravenous cefuroxime followed by a course of oral ciprofloxacin. P. shigelloides seems to be ubiquitous in freshwater world-wide and may cause invasive infections also in cold climate areas.
