==== Group D (enterococci) ====
Many former group D streptococci have been reclassified and placed in the genus ''[[Enterococcus]]'' (including ''E. faecalis'', ''E. faecium'', ''E. durans'', and ''E. avium'').<ref name="pmid17400023">{{cite journal | vauthors = Köhler W | title = The present state of species within the genera Streptococcus and Enterococcus | journal = International Journal of Medical Microbiology | volume = 297 | issue = 3 | pages = 133–150 | date = June 2007 | pmid = 17400023 | doi = 10.1016/j.ijmm.2006.11.008 }}</ref> For example, ''Streptococcus faecalis'' is now ''[[Enterococcus faecalis]]''. ''E. faecalis'' is sometimes alpha-hemolytic and ''E. faecium'' is sometimes beta hemolytic.<ref>Holt et al. (1994). ''Bergey's Manual of Determinative Bacteriology'' (9th ed.).

The remaining nonenterococcal group D strains include ''[[Streptococcus gallolyticus]]'', ''[[Streptococcus bovis]]'', ''[[Streptococcus equinus]]'' and ''[[Streptococcus suis]]''.

Nonhemolytic streptococci rarely cause illness. However, weakly hemolytic group D beta-hemolytic streptococci and ''[[Listeria monocytogenes]]'' (which is actually a [[gram-positive]] bacillus) should not be confused with nonhemolytic streptococci.
