Species

Tractidigestivibacter is a genus of Gram-positive, strictly anaerobic, non-motile, and non-spore-forming bacteria in the family Atopobiaceae. Members of the genus have been isolated from pig and human feces.[1][2] The only species with a validly published name is Tractidigestivibacter scatoligenes.[3]

Taxonomy

The genus was established in 2021 during a phylogenomic reclassification of species previously assigned to the genus Olsenella.[4] Its type species, Tractidigestivibacter scatoligenes, was originally described as Olsenella scatoligenes in 2015 after isolation from pig feces in Denmark.[1] It was transferred to Tractidigestivibacter in 2021.[4]

The name Tractidigestivibacter is derived from Latin words referring to the digestive tract and a rod-shaped bacterium, giving the meaning "a rod from the digestive tract".[3]

Characteristics

Members of the genus are Gram-positive, saccharolytic, strictly anaerobic rods or coccobacilli. They are non-motile and do not form spores.[1][2]

Species

The genus contains one species with a validly published name and one additionally described species whose name has not been validly published:[3]

  • Tractidigestivibacter scatoligenes (Li et al. 2015) Zgheib et al. 2021 – type species
  • "Tractidigestivibacter montrealensis" Benlaïfaoui et al. 2023 – not validly published
