Wound Infection with Aerogenic Aeromonas Strains: a Review of Twenty-seven Cases

Aeromonas spp. have been implicated in a wide spectrum of human disease including wound infection. A review is made of local experience of 27 wound infections from which aerogenic strains of Aeromonas were recovered; of these, Aeromonas was isolated in pure culture from five infections. Twenty-five infections were related to trauma and were community acquired, while two were probably nosocomial. Of the 25 community acquired infections, 16 were associated with contamination by soil and one with water. Twenty-six cases were surgically debrided or a limb or digit amputated, but in only one case was amputation performed because of uncontrolled infection. Fifteen patients received antibiotics inappropriate for the infection, yet the outcome was uniformly good. This series is discussed with a review of the English language literature. Aeromonas is most likely to be isolated when there is contamination of a wound by soil or water; adequate surgical debridement is probably of primary importance.
