Abstract

Caedibacter taeniospiralis is an obligate endosymbiont living in the cytoplasm of Paramecium tetraureliaC. taeniospiralis causes the so-called killer trait, eliminating intraspecific competitors of its host when released into the medium by the concerted action of the unusual protein structure R-body (refractile body) in addition to an as-yet-unknown toxin.
