pluranimalium Vela et al. 2009.
Gram-negative cocci, 1.5–2.0 μm in diameter. Nonspore-forming.
Colonies are circular, nonpigmented, nonhaemolytic, smooth and entire on blood
agar after 48 h incubation at 37 ºC.
Strict aerobe. Growth occurs at 22-37 ºC but not at 42, 15 or 4 ºC. Growth is enhanced
in 5-10% CO2 on 5% sheep blood agar and chocolate agar, in Brain-heart infusion
broth containing 0.5 or 1.5% NaCl, but not with 5.0 or 6.5% NaCl. No growth on
Isolated from pigs and a sheep.
Undetermined. The type strain was isolated from the nasal turbinate of an apparently healthy pig.
