IMMUNOLOGICAL ACTIVITY OF STAPHYLOCOCCUS FOR ANTI-ANTHRAX PRECIPITIN SERUM. II. ON THE COMMON ANTIGEN BETWEEN B. ANTHRACIS AND STAPHYLOCOCCUS

Abstract

Four fractions were obtained by HCl, CuSO4, and Sevag's CCl3COOH precipitation method. A common antigenic substance was observed existing in the HCl, and CCL3COOH precipitated fraction by absorption test and agar dispersion method. The common antigenic substance was thought to be a protein substance having Molisch negative, Biuret positive and Ninhydrin positive reactions. No common antigenic substance was observed in the fractions A-4, and S-4, which were supposed to be polysaccharide. The fractions A-1, -3, S-1, and S-3, containing common antigenic substances, showed 2 to 4 kinds of antigens (reactor). The common antigenic substance is thought to have 1 to 4 substances among them.
