Novel role for Aeromonas jandaei as a digestive tract symbiont of the North American medicinal leech

Appl Environ Microbiol. 2007 Jan;73(2):655-8. doi: 10.1128/AEM.01282-06. Epub 2006 Nov 17.


The gut bacteria of the North American medicinal leech, Macrobdella decora, were characterized. Biochemical tests and DNA sequences indicated that Aeromonas jandaei is the dominant culturable symbiont in leeches from a broad geographic area. In this work we identified a new habitat for A. jandaei, and here we suggest that there is unexpected specificity between leeches and Aeromonas species.
