Species of alpha-hemolytic streptococci possessing a C-polysaccharide phosphorylcholine-containing antigen

Infect Immun. 1993 Jul;61(7):3076-7. doi: 10.1128/iai.61.7.3076-3077.1993.

Abstract

An enzyme-linked immunosorbent assay technique was used to detect and quantify C-polysaccharide-like antigen in strains of alpha-hemolytic streptococci classified into species by following the latest taxonomic recommendations. C-polysaccharide-like antigen is found only in Streptococcus oralis, S. mitis, and S. pneumoniae, which are genetically closely related.
