ADVANCED BACTERIAL
IDENTIFICATION
SOFTWARE
Gram positive, under 2 μm in diameter, spherical cells. Non- or
rarely motile. Facultative anaerobes, cheomoorganotrophs -
metabolism fermentative (CO
2, ethanol, lactic, acetic & formic
acids produced from carbohydrates). Nutritional requirements are
usually complex; optimal growth temperature 37 °C. Catalase-
and oxidase-negative.

Genus Lactovum
Matthies, Gössner, Acker, Schramm
and Drake 2005
Gram-positive round or ovoid cells, nonmotile. Not beta-hemolytic.
Facultatively anaerobic. Catalase-negative. Grow at 10ºC but not
at 45 ºC. Metabolism fermentative. The predominant end product
of glucose fermentation is L(+)-lactic acid.
NOTES

Streptococcus bovis Orla-Jensen 1919
is a later heterotypic synonym of
Streptococcus equinus Andrewes and
Horder 1906

Streptococcus caprinus Brooker et al.
1996 is a later heterotypic synonym of

Streptococcus gallolyticus
Osawa et al.
1996

Streptococcus shiloi Eldar et al. 1995

Streptococcus sanguis and
Streptococcus parasanguis names
have been corrected by Trüper and De'
Clari 1997 as
Streptococcus sanguinis
and S. parasanguinis, respectively
.

Streptococcus parauberis Williams and
Collins 1990 was previously known as
Streptococcus uberis genotype II
