Devriese et al. 1999.
Gram-positive cocci, grouped in chains or small groups. Nonmotile.
Colonies are regular, transparent, non-pigmented, small, under 1 mm diameter,
alpha-hemolytic (colonies are surrounded by pronounced greening zones with
demarcated edges). Grow at 37 and 42 ºC, no growth under 25 ºC. Most strains
produce precipitates and clear supernatants in broth. Growth media: Blood agar,
Brain Heart Infusion broth. May grow (or not) in 6.5 % NaCl broth.
Isolated from milk, genital tract and tonsils of cattle, from tonsils of a goat and a cat and from the crop and the respiratory tract of
canaries.
Isolated from mastitic milk of a dairy cow. May be a normal inhabitant of the bovine genital tract.

Strains of Streptococcus pluranimalium resemble Streptococcus acidominimus and
some reference strains of the latter have been re-identified as
S. pluranimalium.

Positive results for hippurate hydrolysis, activity of leucine arylamidase, alanine-phenylalanine-proline arylamidase, hydrolysis of
