Olsenella faecalis Han et al. 2019 | |
Paratractidigestivibacter faecalis is a Gram-positive and strictly anaerobic bacterium in the genus Paratractidigestivibacter and family Atopobiaceae. It was first described as Olsenella faecalis in 2019 after isolation from a human fecal sample in South Korea.[1] It has also been isolated from the feces of pigs in Canada.[2]
In 2021, phylogenomic analyses supported transfer to a new genus, yielding the combination Paratractidigestivibacter faecalis.[3]
Taxonomy
Comparative genomic and phylogenetic data showed strain JCM 32256 forms a distinct lineage within Atopobiaceae; therefore, Zgheib et al. established the genus Paratractidigestivibacter and the new combination P. faecalis.
Morphology and physiology
Cells are rod-shaped, non-motile, non-spore-forming and strictly anaerobic. Colonies on reinforced clostridial agar are round and cream-coloured. Optimal growth occurs at 37 °C and pH 7.0.
Etymology
- faecalis – Latin genitive adjective "of faeces", indicating the source.
- Paratractidigestivibacter – from Greek para- "beside", Latin tractus digestivus "digestive tract", and Neo-Latin bacter "rod."
