eubacterium

Doesn't it say right in this linked summary article that it is Eubacterium rectale and Coprococcus eutactus?

Apparently, the genomic evidence is strong that the original host was an archaeon an the original invader (later to become mitochondria) was a eubacterium.

Lane gives an extensive theoretical analysis of the sequence of events wherein a eubacterium was engulfed by an archea, and the resulting endosymbiosis that was the beginning of complex (eukaryotic) life.

"Several microbial species were significantly enriched in children with higher cognitive function scores (eg, Alistipes obesi, Asaccharobacter celatus, Eubacterium eligens, and Faecalibacterium prausnitzii), with Sutterella wadsworthensis being the only species significantly negatively associated with these scores."
