Species/Subspecies: Streptococcus equi subsp. ruminatorum
Category: Causes hemolysis
Etymology: Genus name: twisted (like a chain) coccus (coccus means a grain or a berry and referrs to any spherical microorganism).
Species epithet: of horse.
Subspecies epithet: of ruminants.
Significance:  [Of minor importance]   
Taxonomy:
Phylum
Firmicutes
Class
Bacilli

Taxonomy/phylogeny:
 
About 100 species have been described within the genus Streptococcus. Many species within the genus Enterococcus have earlier been classified as streptococci and, thus, they are closely related. S. equi consists of three subspecies, which are related to S. devriesei.
Comment:Belongs to Lancefield's group C streptcocci.
