Building evidence implicates the gut microbiome in regulating animal digestion, nutritional acquisition, immune regulation, development, and even mood regulation. Because of the difficulty of assigning causative relationships in complex gut microbiomes a simplified model for testing hypotheses is necessary. Previous research in Hirudo verbana has suggested this animal as a highly simplified and tractable animal model. Our data show that Macrobdella decora may work just as well as H. verbana without the drawback of being an endangered organism and with the added convenience of easy access to field-caught specimens. The similarity of the microbial community structure of species from two different continents reveals the highly-conserved nature of the microbial symbionts in sanguivorous leeches and confirms the medicinal leech as a highly simplified, natural animal model in which to study gut symbioses.
