Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

group D streptococci

Any Streptococcus species, including S. bovis and S. equinus, that is not destroyed by bile or exposure to heat. These strains can be destroyed in a laboratory by a 6.5% concentration of sodium chloride. Many Group D streptococci have been reclassified and placed in the genus Enterococcus (including S. faecalis, S. faecium, S. durans, and S. avium). For example S. faecalis is now E. faecalis. The remaining strains of nonenterococcal Group D streptococci include S. bovis and S. equinus.
