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. porcinus is closely related to S. uberis.
Comment:Belongs to Lancefield's group E, P, U or V streptcocci.
