Rapidly Progressive Soft Tissue Infection of the Upper Extremity With Aeromonas veronii Biovar sobria.

Aeromonas veronii, a bacterium found in freshwater, is an unusual pathogen in healthy patients. We present a case report of a rare, aggressive subtype in a young, immunocompetent individual. History of injury in an aquatic environment and culture data are key for identification of the causal agent and should dictate acute clinical management and antibiotic therapy. Coverage should include cephalosporins, quinolones, or sulfas if Aeromonas is suspected, and adjusted depending on culture and sensitivity. Early surgical exploration, incision and drainage, and appropriate antimicrobial therapy are the cornerstones for successful treatment of these aggressive, sometimes life-threatening infections.
