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. | ||||||||
