Characterization of the digestive-tract microbiota of Hirudo orientalis, a european medicinal leech.
FDA-approved, postoperative use of leeches can lead to bacterial infections. In this study, we used culture-dependent and culture-independent approaches to characterize the digestive-tract microbiota of Hirudo orientalis. Surprisingly, two Aeromonas species, A. veronii and A. jandaei, were cultured. Uncultured Rikenella-like bacteria were most similar to isolates from Hirudo verbana.

408e Although blood letting and the use of leeches dates back to pharaonic Egypt,1 the U.S. Food and Drug Administration only approved the use of Hirudo medicinalis as a medical device in 2004.2 Leeches are used by plastic,3–7 maxillofacial,8–10 and other surgeons11,12 to aid salvage of venously congested pedicled flaps,13,14 freetissue transfers,3,15–17 replanted digits,6,18–25 ears,26–32 lips...
متن کاملCulture-independent characterization of the digestive-tract microbiota of the medicinal leech reveals a tripartite symbiosis.
Culture-based studies of the microbial community within the gut of the medicinal leech have typically been focused on various Aeromonas species, which were believed to be the sole symbiont of the leech digestive tract. In this study, analysis of 16S rRNA gene clone libraries confirmed the presence of Aeromonas veronii and revealed a second symbiont, clone PW3, a novel member of the Rikenellacea...
متن کاملSymbiosis of Aeromonas veronii biovar sobria and Hirudo medicinalis, the medicinal leech: a novel model for digestive tract associations.
Hirudo medicinalis, the medicinal leech, is applied postoperatively in modern medicine. Infections by Aeromonas occur in up to 20% of patients unless a preemptive antibiotic treatment is administered. The associated infections demonstrate the need for a better understanding of the digestive tract flora of H. medicinalis. Early studies reported the presence of a single bacterial species in the d...
متن کاملCharacterization of shed medicinal leech mucus reveals a diverse microbiota
Microbial transmission through mucosal-mediated mechanisms is widespread throughout the animal kingdom. One example of this occurs with Hirudo verbana, the medicinal leech, where host attraction to shed conspecific mucus facilitates horizontal transmission of a predominant gut symbiont, the Gammaproteobacterium Aeromonas veronii. However, whether this mucus may harbor other bacteria has not bee...
