Gram-negative rods with rounded ends, 0.7 x 1.5-1.8 μm, occuring singly or in pairs.
Non-motile. Non-spore-forming.
Non-motile. Non-spore-forming.
After 48 h of incubation on trypticase soy agar at 28 ºC, colonies are beige, smooth,
shiny, non-translucent, round, mostly regular in shape with entire edges, ~ 1-1.5 mm
in diameter. Grows on MacConkey agar. Growth occurs at 15-30 ºC (weak or no
growth at 37 ºC) and at pH 6-7. No growth at 4, 40 or 45 ºC. Grows in 1% and 2%
(weakly) NaCl. Aerobic.
