Necrotizing fasciitis caused by Aeromonas hydrophila.

Aeromonas Hydrophila is a gram-negative bacillus commonly found in soil, sewage, and fresh or brackish water in many parts of the United States. In healthy people, the most common clinical manifestations attributed to Aeromonas are diarrhea and soft tissue infections. In people with suppressed immune systems or liver disease, A hydrophila can cause meningitis, endocarditis, peritonitis, hemolytic-uremic syndrome, or septicemia. We present the first known case of fulminant necrotizing fasciitis from A hydrophila that is not associated with trauma, liver disease, or immunosuppression.
