A fatal case of Vibrio vulnificus presenting as septic arthritis

Vibrio vulnificus is an invasive gram-negative bacillus that may cause necrotizing cellulitis, bacteremia, and/or sepsis. Although V vulnificus infection is uncommon, it is frequently fatal and is usually attributed to ingestion of raw shellfish or traumatic exposure to a marine environment; patients are also often found to have a hepatic disorder (cirrhosis, alcohol abuse, or hemochromatosis) or an immunocompromised health status, and most commonly present with septicemia or a wound infection. We describe a patient who presented with septic arthritis as the first clinical manifestation of a V vulnificus infection. The organism was subsequently identified in a synovial fluid aspirate.
