Gram-negative rods, 1 x 2 μm. Non-motile. Non-spore-forming.
Colonies on NA are smooth, beige, and circular with entire edges. Optimum growth
temperature is 28-30 ºC. Grows at pH 4.5-11.5 or in the presence of 1-7% NaCl. Good
growth occurs after 48 hrs on NA, BHI agar, TSA, and R2A agar, and on MacConkey
agar at 30 ºC and 37 ºC. Growth occurs on NA after 24h to 3 days at 8-45 ºC, but not at
4 or 50 ºC. Facultatively anaerobic.
