Gram-positive, coccoid to rod-shaped cells, occurring in chains. Non-motile.
Colonies on trypticase soy agar supplemented with 5% sheep blood incubated at 35
ºC for 24 h are 1 mm in diameter, grey-white, circular, convex, with an entire margin and
alpha-haemolytic. Growth occurs at 10 ºC, but not at 45 ºC in heart infusion broth. No
gas is produced in MRS broth. Grows in the presence of bile, 6.5% NaCl and pyruvate,
but not tellurite. Facultatively anaerobic.

Isolated from ground beef. Resistant to optochin. Sensitive to vancomycin.
