Extracellular antigens of serotype III group B streptococci.

RESUMO
Two sialic acid-containing type III group B streptococcal antigens were obtained from a supernatant growth medium, purified by anion exchange or gel filtration, and found to be free of group B reactivity. Quantitation of the high-molecular-weight extracellular type III antigen indicated that approximately 20-fold more antigen was recoverable from the growth medium than could be obtained by neutral buffer extraction of whole cells.
