Anaerovoracaceae [G1] infirmum (HMT-105)

Bacteria;Bacillota;Clostridia;Peptostreptococcales;Anaerovoracaceae;Anaerovoracaceae [G1] infirmum

Taxon Description: Eubacterium infirmum belongs to a phylogenetic cluster distant from Eubacterium limosum the type species of the genus and is therefore not a member of Eubacterium sensu stricto. Along with many other members of this poorly-defined genus E. infirmum will be assigned to a novel genus in due course.

Disease Associations: Isolated from subgingival plaque in periodontitis.
Prevalence and Source: Found in the human mouth
Phenotypic Characteristics: Cells are obligately anaerobic non-spore-forming nonmotile Gram-positive short rods (0.5 µm by 1-2 µm) [1]. Cells occur singly. Asaccharolytic. End-products of metabolism are moderate amounts of acetate and butyrate. The mol% G+C of the DNA is 38.
Cultivability: Slow growth on Fastidious Anaerobe Agar + 5% horse blood plates. After 7 days colonies are approximately 1 mm in diameter circular convex and translucent.
