Collins et al. 1986. Lancefield group D.
Gram-positive, ovoid cells, grouped mostly in pairs or short chain. Nonmotile.
Colonies on blood agar or nutrient agar are circular, smooth, and entire. A yellow
pigment is produced. Nonhemolytic. Growth occurs at 10 and 45 ºC, in 6.5% NaCl,
and at pH 9.6. Facultatively anaerobic.
Isolated from cows, the hands of milkers, plants and soil.
Unknown.
