Gram-negative rods, 1-3 µm. Non-spore-forming. Motile.
Colonies on TSA incubated at 37 ºC for 24 hours are 2-3 mm in diameter, opaque,
circular and yellow. In TSB, grows at 45 ºC (optimum 37 ºC), but not at 5 ºC. No
haemolysis is observed on sheep blood agar at 37 ºC. Grows at pH 5-10 and in up to
7 % (w/v) NaCl. Facultatively anaerobic.
