Abstract
1. The immunological behavior of two cell constituents of nonhemolytic streptococci has been studied, (a) One, the so called nucleoprotein, is relatively non-specific and gives rise to an antibody which shows group reactions with nucleoproteins of related species. (b) The other is non-protein by qualitative chemical tests. Preliminary chemical examination has indicated that it may be a carbohydrate. Although this substance is highly reactive with the specific antibodies produced by the intact bacterial cell, yet in its chemically purified condition it is probably non-antigenic. Specific serological reactions with this substance are dosely related to specific agglutination of the microorganism.
