Gram-negative, 0.46-0.66 μm diameter, coccobacilli. Non-motile. Non-sporulated.
Colonies are white, circular, convex and smooth after 24 h of incubation on PCA.
Growth occurs at 10-37 ºC, pH 5.0-9.5 and in the presence of up to 3% NaCl. After 7
days of incubation, no growth is observed at 6 or 40 ºC or in the presence of 5% NaCl.
Growth does not occur in an anaerobic atmosphere. Non-haemolytic on Columbia
agar with 5% sheep blood.
