The Mexican leech Haementeria officinalis and its nutritional symbiont as a model system for the study of strict blood-feeding animal-microbe symbioses and bacteriocyte development

Project description

Understanding bacteria that help blood-sucking leeches maintain balanced nutrition

Humans host a rich diversity of microorganisms collectively known as the microbiome, most of which benefits us in many ways. Perhaps it is not surprising, then, to learn that we are not the only organisms with such beneficial symbiotic relationships. Leeches that feed only on blood would be deficient in vitamin B without the help of bacteria that live in a specialised organ. With the support of the Marie Skłodowska-Curie Actions programme, the LEECHSYMBIO project is investigating this unique microbe–host interaction with the goal of establishing this leech as a model system for future studies of nutritional blood-feeding symbioses.
