Aeromonas hydrophila infection of a puncture wound

Aeromonas hydrophila is a gram-negative organism generally considered a pathogen of low virulence, rarely reported as causing infection in man. Recently it has been recognized as causing infection in wounds. This article reports the case of a patient who suffered a puncture wound while standing in a fresh water lake. He subsequently developed a rapidly progressing cellulitis requiring hospitalization. This organism was cultured from the wound and responded dramatically to appropriate antimicrobial therapy.
