Gram-positive, large ovoid cells, occurring in short chains. Non-motile. Non-spore-
forming.
Colonies on 5% blood agar are small, viridans streptococcus-like, alpha-haemolytic
and non-pigmented. Facultatively anaerobic. No growth at 10 or 45 ºC. Does not
tolerate tellurite (0.04%) or tetrazolium (0.25%). Most strains grow in 6.5% NaCl.
Grows on bile-esculin agar.
Isolated from human and animal (sheep) clinical specimens. Vancomycin-sensitive.
Isolated from blood cultures of patients with sepsis, meningitis, and bacteremia, urine of patients with urinary tract infections,
cerebrospinal fluid, and wounds. Isolated from blood and brain samples from lambs with meningoencephalitis.
