Gram-positive cocci, non-motile, grouped in pairs, tetrads or small groups.
Non-spore-forming.
Non-spore-forming.
Alpha-hemolytic colonies on 5% horse or sheep blood agar. Non-pigmented. Growth
does not occur at 10 ºC. Most strains may grow at 45 ºC. Growth occurs in 6.5% (w/v)
NaCl. Grow at 37 ºC, optimum at 25-30 ºC. Grows in MRS broth/agar. Facultatively
anaerobic. Optimum pH value for growth is between 8.5-9.0. Grows well in Trypticase
Soy broth containing yeast extract.
