Gram-negative rods with rounded ends, ~ 1 μm in length, occuring as single units or
in pairs. Non-motile.
in pairs. Non-motile.
Colonies on trypticase soy agar after 48h incubation at 28 ºC are round, about 1 mm
in diameter, smooth, shiny, non-translucent, with entire margins and a white-creamy
color. Grows on MacConkey agar. Growth occurs at 15-28 ºC (the type strains can
grow at 37°C) and at pH 6-7 in nutrient broth at 28 ºC. Grows aerobically (anaerobic
growth not tested).
