Selenomonas ruminantium

RANK: Species

TAXONOMY: Terrabacteria group -> Firmicutes -> Negativicutes -> Selenomonadales -> Veillonellaceae -> Selenomonas -> Selenomonas ruminantium


The genus Selenomonas constitutes a group of motile crescent-shaped bacteria within the Veillonellaceae family and includes species living in the gastrointestinal tracts of animals, in particular the Ruminants. A number of smaller forms discovered with the light microscope are now in culture but many, especially the large selenomonads are not, owing to their fastidious and incompletely known growth requirements. Selenomonas ruminantium is a propionate producer.

This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072]
