Host association and intracellularity evolved multiple times independently in the Rickettsiales

The paper investigates the evolution of host association and intracellularity in Rickettsiales by analyzing genomic data and functional reconstructions, finding that these traits evolved multiple times independently.

Ciliated protozoa from industrial WWTP activated sludge: a biodiversity survey including trophic interactions and redescription of Bakuella subtropica (Spirotrichea, Hypotrichia) according to Next Generation Taxonomy

The paper characterizes ciliate communities in a wastewater treatment plant, identifies trophic interactions, and redescribes a species using modern taxonomy.

Outwitting planarians antibacterial defence mechanisms: Rickettsiales bacterial trans-infection from Paramecium multimicronucleatum to planarians

The paper demonstrates that a Rickettsia-like endosymbiont from a ciliate can be trans-infected into planarians, detected up to day 7 post-infection.

Next generation taxonomy: integrating traditional species description with the holobiont concept and genomic approaches - The in-depth characterization of a novel Euplotes species as a case study

The paper introduces a new taxonomy framework integrating holobiont concepts and genomic analysis, exemplified by describing a novel Euplotes species and its symbiont.

The extracellular association of the bacterium \"Candidatus Deianiraea vastatrix\" with the ciliate Paramecium suggests an alternative scenario for the evolution of Rickettsiales

The paper describes a novel Rickettsiales bacterium associated with Paramecium that replicates extracellularly, suggesting an alternative evolutionary scenario for intracellularity in Rickettsiales.
