Aeromonas hydrophila infections following clinical use of medicinal leeches: a review of published cases.
Ten Aeromonas hydrophila infections following postsurgical leech applications have been reported. These cases indicate that postsurgical wounds and damaged tissue can provide entry for either acute or delayed A. hydrophila infection. These infections can range from localized cellulitis to progressive myonecrosis and sepsis. These infections may occur with measurable frequency in groups of patients exposed to leeches. Based on this review, it is recommended that leeches be applied only to tissue with a reasonably certain arterial supply; that patients receive antibiotics against A. hydrophila prior to leech administration; and that consideration be given to prolonged antibiotic administration to patients discharged home with open wounds or questionably viable tissue after leech administration.
