Cells are Gram-reaction-positive, nonmotile, non-spore-forming coccobacilli and short rods that occur singly, in pairs (V, T, and palisade formations), or in clusters. Cells vary in shape and size in different media. Cells from 24-h-old broth cultures are Gram-reaction-positive but may be Gram-reaction-variable in older cultures. Pinpoint, in most cases β-hemolytic colonies occur on sheep blood agar after 24 h of incubation. After 48–72 h of incubation, colonies are 0.5–1.5 mm in diameter, convex, circular, and translucent with entire edges. Aerobic and facultatively anaerobic. Strictly fermentative. Lactic acid is the primary metabolic product in glucose–yeast extract broth, but acetate and succinate are minor products. The peptidoglycan is of the type A5a, variations l-Lys–l-Ala–l-Lys–d-Glu or l-Lys–l-Lys–d-Glu. The muramic acid residue of the peptidoglycan is N-acetylated. Characteristic whole-cell sugars are rhamnose and glucose. Mycolic acids are not present. The long-chain fatty acids are primarily straight-chain saturated and monounsaturated in addition to traces of branched-chain fatty acids of the iso-/anteiso type. The phospholipid type is type PI, comprising diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylinositol (PI), and an unknown phosphoglycolipid (PGL) of unknown composition. The principal menaquinone is MK-10(H4).

DNA G + C content (mol%): 56–66.

Type species: Trueperella pyogenes Yassin et al. 2011^VP.
