Gram negative cells, nonmotile, rod-shaped.
Colonies are circular, low convex and regular with an entire margin; the surface of the
colonies is smooth, shiny, grayish and opaque 1.5-2.0 mm in  diameter after 24 h and
3.5-4.0 mm after 48 h at  37 ºC. Hemolysis is negative. V-factor independent. Growth
on Mac Conkey agar is negative.
Is a normal component of the oropharyngeal and genital tract flora of laboratory white mice.
