Abstract
AbstractRickettsialesare a lineage of obligatorily intracellularAlphaproteobacteria, encompassing important human pathogens, manipulators of host reproduction, and mutualists. Here we report the discovery of a novelRickettsialesbacterium associated withParamecium, displaying a unique extracellular lifestyle, including the ability to replicate outside host cells. Genomic analyses show that the bacterium possesses a higher capability to synthesize amino acids, compared to all investigatedRickettsi
