Gram-negative, small rods, 0.8-2.4 µm, nonmotile and non-sporulated.
Colonies are graysh and opaque on chocolate agar; 2 mm in diameter after 48 hours
of incubation. Cultures have a characteristic pungent smell. Hemolysis variable.
V-factor dependent growth.

Isolated from the upper respiratory tracts of pigs , where they constitute part of the residing mucosal flora.
Is not pathogenic to pigs and have a low potential for colonization of the upper respiratory tract of gnotobiotic piglets.
