Gram-positive (appear Gram-variable) rods, 0.2-0.4 x 0.5-2.5 µm. Non-motile.
Growth is observed at 22-37 ºC, with optimal growth at 37 ºC. Growth is barely visible
at 48 h, but colonies are fully formed at 60 h; colonies are grey, smooth, convex and
smaller than those of E. rhusiopathiae on blood agar, and are gamma-haemolytic.
Grows on tryptic soy agar supplemented with 5% sheep blood. Aerobic.
