Abstract (EN): Bacterial endosymbiosis is widespread in hydrothermal vent bivalves, and is typically developed in gill bacteriocytes, while it has never been described in the digestive gland. Using ultrastructural examination and DNA amplification analyses, we provide evidence for the existence of a potentially new group of environmental bacteria in the digestive gland of Bathymodiolus azoricus, which are genetically distinct from sulphur-oxidiser endosymbionts in its gills. The 16S rRNA partial gene sequences showed 99% identity in the gill and the digestive gland. Our results indicate that the same bacteria phylotypes are associated with different tissues in the host, and also that they do not result from a random infestation by free-living forms.
