Poyart et al. 2002. One of the strain of this species has been previously characterized as
Streptococcus infantarius subsp. coli
Schlegel et al. 2000.
Lancefield group D or non-groupable.
Gram-positive cocci, nonsporulated, nonmotile, grouped in pairs or short chains
Colonies on blood agar are circular, smooth, entire, non-pigmented, alpha-hemolytic.
Homogeneous growth in BHI and glucose broths after 18 h incubation at 37 ºC.
Growth also occurs in MRS broth without gas production. No growth occurs in 6.5%
NaCl broth. Facultatively anaerobic.
Isolated from human specimens: cerebrospinal fluid, urine & stool.
