Gram-positive, large ovoid cells, occurring in pairs or short chains. Non-motile.
Colonies on horse blood agar are round, smooth, domed, 0.5 mm in diameter (in 48h
at 30 ºC), alpha-haemolytic and non-pigmented. Facultatively anaerobic. No growth at
10 or 45 ºC.
Isolated from powdered tobacco. One strain has been isolated from sheep (unpublished data (2)).
