Sensitivities of Aeromonas hydrophila cultured from medicinal leeches to oral antibiotics
Research article published in J Reconstr Microsurg (1990)
Abstract
Infections associated with medicinal leech application are caused by Aeromonas hydrophila, an organism that resides in the leech gut. We cultured the intestinal tracts of 25 leeches and evaluated the efficacy of oral antibiotics against Aeromonas hydrophila. Cultures of this organism showed no sensitivity to ampicillin and inconsistent sensitivity to cephalothin (equivalent to cephalexin). The Aeromonas hydrophila cultures did show consistent sensitivity to ciprofloxacin, tetracycline, and trimethoprim-sulfamethoxasole. These three antibiotics should be considered if oral antibiotic coverage is used in association with leech application.

Zusammenfassung
Cultures of Aeromonas hydrophila from 25 medicinal leeches; consistent sensitivity to ciprofloxacin, tetracycline, and trimethoprim-sulfamethoxazole; no sensitivity to ampicillin.
Warum dies für die Hirudotherapie relevant ist
This study cultured Aeromonas hydrophila from the intestinal tracts of 25 medicinal leeches and tested sensitivity to oral antibiotics, finding no sensitivity to ampicillin, inconsistent sensitivity to cephalothin, and consistent sensitivity to ciprofloxacin, tetracycline, and trimethoprim-sulfamethoxazole. This is directly relevant to hirudotherapy practice, as A. hydrophila is the primary pathogen responsible for infections associated with medicinal leech application, and these findings can guide prophylactic or therapeutic antibiotic choices. The study provides practical, actionable data from a meaningful sample size. However, it is an in vitro sensitivity study and does not report clinical outcomes of antibiotic prophylaxis in leech-treated patients, so the translation to in vivo efficacy and clinical infection prevention requires further corroboration.
