Serological relationships of type I antigens of group B streptococci.
Some of the complex antigenic relationships of type I group B streptococci from various clinical sources were defined by means of immunodiffusion, absorption, and precipitin tests. Three predominant types are described: Ia, Ib, and Ii. Methods for preparing antisera for differentiating type I strains are presented.
