Abstract:
:A simple scheme for the speciation of clinical isolates of "viridans" streptococci based on nine physiological characteristics is presented. Use of this scheme will enable successful speciation of most "viridans" strep isolates in any laboratory and allow for the accumulation of data necessary for the definition of clinical syndromes or unique clinical problems associated with particular species.
