clusters. Non-sporeforming. Non-motile.
Colonies on BHI agar supplemented by 7% sheep blood are non-pigmented, circular
with whole margins, convex, smooth, glistening, 1-2 mm in diameter at 37 ºC after 24
h incubation. Weak growth of pinpoint colonies with positive aesculin reaction occurs
on kanamycin aesculin azide agar at 37 ºC after 24 h. No growth is observed on
Slanetz-Bartley agar. Grows at 15-42 ºC, but not at 10 or 45 ºC or in the presence of
6.5 % NaCl. Facultatively anaerobic.
