IMMUNOCHEMICAL STUDIES ON THE CROSS-REACTIVITY BETWEEN STREPTOCOCCAL AND STAPHYLOCOCCAL MUCOPEPTIDE

Abstract
Particulate mucopeptides of Group A-variant streptococci and Staphylococcus aureus, solubilized by ultrasonic treatment, give a precipitin reaction with the sera of rabbits immunized with Group A-variant streptococci. γ-G globulin antibodies have been recovered from these sera which react with the mucopeptides but not with the Group A-variant carbohydrate.
