Gram-positive rods. Non-motile. Non-spore-forming.
Colonies on 5% horse blood agar after 24 h growth at 37 ºC at normal atmospheric
conditions are small pin-point sized, round, flat grey with smooth contours. Alpha
haemolysis is produced. Grows at pH 6-8, weakly at pH 9. Normal growth between
20-40 ºC. Slower growth was observed at 15 and 10 °C (colonies visible after six
days), whereas no growth was observed after nine days of incubation at 5 ºC.

Isolated from three Indian yellow-nosed albatross (Thalassarche carteri) chick carcasses.
Associated with yellow-nosed albatross chick mortalities.
