Gram positive cocci, elongated, often lanceolate. Occur singly, in pairs or in small
groups. Non-motile.
groups. Non-motile.
Colonies on Columbia agar with sheep blood are small (1–2 mm), not pigmented,
translucent, shining and regular. Greening haemolysis. Turbid growth & deposit in
liquid media.
Grows in the presence of 6.5% NaCl. Grows and produces blackening on bile
aesculin agar. Poor growth on Slanetz and Bartley medium containing 0.04% sodium
az ide. Grows well between 25 and 42 °C. Addition of 5% CO2 does not enhance
growth.
