Leech-borne Serratia marcescens infection following complex hand injury.
Case report published in British journal of plastic surgery (1998)
Abstract
Leeches are commonly used in the postoperative course of plastic surgical operations where there is venous congestion in a pedicled or free flap. They provide a temporary relief to venous engorgement whilst venous drainage is re-established. It is known that leeches can carry Aeromonas hydrophila infection, and a second or third generation cephalosporin antibiotic has traditionally been given as prophylaxis against infection. We report a new observation that leeches can carry Serratia marcescens and give rise to clinically significant infection. The implication for prophylaxis and treatment of leech-associated cellulitis is discussed.

Por qué esto importa para la hirudoterapia
This case report documents a new observation that medicinal leeches can carry Serratia marcescens and give rise to clinically significant infection. The abstract describes leeches as commonly used in plastic surgical operations where there is venous congestion in a pedicled or free flap, notes that Aeromonas hydrophila is the traditionally recognized leech-associated pathogen with second- or third-generation cephalosporin prophylaxis as standard, and discusses implications for prophylaxis and treatment of leech-associated cellulitis. This article is directly relevant to ASH's domain as it concerns a safety issue in clinical leech use—bacterial transmission risk—and challenges existing prophylaxis assumptions. However, it is a case report, so its findings about Serratia as a leech-borne pathogen are limited in scope and cannot establish prevalence or comprehensive recommendations.
