Nanosynbacter sp. strain BB002, was isolated from the human oral cavity on its basibiont bacterial host Actinomyces sp. oral taxon 171 strain F0337, related to Actinomyces oris. As a member of the Saccharibacteria within the candidate phylum radiation group (CPR), its reduced genome facilitates the survival as an ultrasmall (<0.2 μm) epibiont.
