Abstract

Increased use of medicinal leeches (Hirudo medicinalis) for the treatment of venous congestion in flaps and replanted parts has coincided with reports of soft tissue infections following leech application. We cultured the gullets of 20 medicinal leeches to re-examine the antibiotic sensitivities of Aeromonas hydrophila, the leech enteric organism associated with reported infections. These isolates reflected reported resistance to penicillin and first generation cephalosporins as well as sensitivity to gentamicin, tetracycline and chloramphenicol. Additionally, the cultures were sensitive to cefamandol, cefoxitin and two third generation cephalosporins (cefoperazone and cefotaxime). These findings suggest that cefamandol, cefoxitin and some third generation cephalosporins may have a role as perioperative antibiotics in replantation and flap surgery. These antibiotics might provide prophylaxis against Aeromonas hydrophila infection when leech use is required.

Zusammenfassung

Culture of 20 medicinal-leech gullets confirming Aeromonas hydrophila resistance to penicillin and 1st-generation cephalosporins, with sensitivity to gentamicin, tetracycline, chloramphenicol, cefamandol, cefoxitin, and 3rd-generation cephalosporins.

Warum dies für die Hirudotherapie relevant ist

This study cultured the gullets of 20 medicinal leeches (Hirudo medicinalis) to re-examine antibiotic sensitivities of Aeromonas hydrophila, the leech enteric organism linked to soft tissue infections following leech application in flap and replantation surgery. Isolates were resistant to penicillin and first-generation cephalosporins but sensitive to gentamicin, tetracycline, chloramphenicol, cefamandole, cefoxitin, and third-generation cephalosporins (cefoperazone, cefotaxime). This is directly relevant to ASH's domain: it provides prophylaxis guidance for Aeromonas infection risk associated with therapeutic leech use. The honest caveat is that this is an in-vitro microbial sensitivity study of cultured isolates, not a clinical trial of antibiotic prophylaxis outcomes, and it does not report infection rates, patient outcomes, or resistance mechanisms; the suggested prophylaxis role is inferential.
