Characterization of Blood Culture Isolates of <i>Streptococcus dysgalactiae</i> subsp. <i>equisimilis</i> Possessing Lancefield's Group A Antigen
1 Dec 1999
Abstract excerpt
For three human blood culture isolates of beta-hemolytic streptococci with Lancefield's serogroup A antigen, phylogenetic analysis of the 16S rRNA genes confirmed biochemical identification as Streptococcus dysgalactiae subsp. equisimilis.
