Gram-negative, pleomorphic rods. Non-motile.
Colonies on blood agar are approximately 1.0-1.5 mm in diameter, smooth and shiny,
opaque, circular and slightly raised with an entire margin and soft consistency and
yellow tinge after 24 h aerobic incubation at 37 ºC. Non-haemolytic on 5% bovine
blood agar. No requirement for X-factor (positive in porphyrin synthesis) or V-factor (no
NAD requirement). No growth on MacConkey medium. Growth with KCN is positive for
most strains.
