Simultaneous production of two capsular polysaccharides by pneumococcus. I. Properties of a pneumococcus manifesting binary capsulation

R AUSTRIAN et al. J Exp Med. .

Abstract

Pneumococci manifesting binary capsulation have been produced through the agency of transformation reactions. Such cells produce two capsular polysaccharides which are closely similar if not identical with those produced by corresponding singly capsulated strains. Binary capsulation in pneumococcus provides a new basis for serologic cross-reactivity in this species.
