Shewanella species are Gram-negative, saprophytic, motile bacilli. Exposure to aquatic environment and raw fish ingestion have been defined as significant associated risk factors. The two species most commonly associated with human infections are Shewanella algae and Shewanella putrefaciens and major portion of infections (80%) caused by the former. Herein, we report a case of Shewanella septicaemia in a 70-year-old man in Omaha, NE who had no exposure to aquatic environment. To date, no defined treatment guidelines are present due to rarity of Shewanella infections, which is contributing to emerging antibiotic resistance.
