Coenye et al. 2003, type species of the genus.
Gram-negative, 1-2 μm long, coccoid cells that occur as single units, in pairs or in
short chains. Motility is strain dependent.
Colonies on nutrient agar are flat or slightly convex with smooth margins with a colour
ranging
from white to light brown. Growth occurs at  28 and 42 ºC. Grows in 0 to 4.5%
NaCl concentration.
Isolated from various human clinical samples (leg wounds, ankle wound, sputum and faces).
Undetermined.
