Gram-negative rods, 0.9-1.0 x 3.0-10.0 µm. Nonmotile. Spores are oval to oblong,
central to subterminal.
central to subterminal.
Colonies are 3-5 mm in diameter, round, with undulate margin and are slightly convex,
opaque, glossy, and grayish-white. Hemolysis is negative. Anaerobic. Cultures in PYG
broth have a pH of 4.8 after incubation for 6 days.
Growth temperature 30-45 ºC, optimum 37-40 ºC. No growth at 20 or 50 ºC.
