Human soft tissue infection by the emerging pathogen Shewanella algae

Shewanella soft tissue infections usually occur in immunocompromised patients with a preexisting cutaneous ulcer, mostly after exposure to a marine environment or contaminated water. A 35-year-old male presented with a non-healing ulcer over the distal end of his right leg but had no predisposing factors. Cultures of exudates from the wound grew Shewanella on repeated occasions. Recovery was uneventful following surgical debridement and antimicrobial therapy. Early suspicion, diagnosis, and treatment with potent antibiotics are needed to prevent any further complications resulting from infection by this emerging pathogen.
