Historical synonym: "Enterococcus dispar-like" De Graef et al. 2005.
Gram-positive spherical cells, arranged in small groups. Nonmotile.
On blood agar, colonies are circular, non-pigmented, smooth, shiny and milky, 3 mm
in diameter. Homogeneous growth in brain-heart infusion broth (Oxoid).
Growth is not enhanced by the addition of 5% CO
2. Growth temperature 25 to 42 ºC,
optimum 37 ºC. Grow in 6.5% NaCl broth. On Edward’s Streptococcus selective
medium, aesculin-degrading colonies are formed. Blackening occurs on aesculin
bile agar. Strains grow and tetrazolium chloride is reduced on Slanetz & Bartley agar.
Isolated from faecal samples of healthy dogs.
Unknown.
