This is a case report of a 56-year-old man, who presented with a very rare cause of erysipelas and bacteraemia caused by the Gram-negative bacillus Shewanella algae. To our knowledge, this is the first reported case of imported Shewanella-infection in Denmark. The patient, who had a history of liver cirrhosis, returned home from a one-month vacation in Thailand. All four blood cultures were positive for S. algae. The patient was treated successfully with IV meropenem and oral ciprofloxacin. S. algae can cause severe local and systemic infection and is not sensitive to standard treatment with penicillin.
