Wound infection caused by Kanagawa-negative Vibrio parahaemolyticus.

Kanagawa-positive Vibrio parahaemolyticus strains are considered to be human pathogens and are most commonly associated with summer diarrhea. Kanagawa-negative strains are most frequently isolated from the environment and are generally considered to be nonpathogens. We report a wound infection caused by a Kanagawa-negative V. parahaemolyticus strain. The infection occurred in October, an unusual time of the year for a V. parahaemolyticus infection to occur in the mid-Atlantic region of the United States.
