STUDIES OF STREPTOCOCCAL CELL WALLS VI

Abstract

Hayashi, James A. (University of Illinois College of Medicine, Chicago) and Gerald Walsh. Studies of streptococcal cell walls. VI. Effects of adjuvants on the production of type-specific antibodies to cell walls and isolated M protein. J. Bacteriol. 82:736–742. 1961.—Mineral oil adjuvant was shown to assist in type-specific immunization of rabbits, when use was made of isolated cell walls or pH 2-extracted M protein from type 14 group A hemolytic streptococci. The antibodies produced were type specific, and passively protected mice that were challenged with virulent type 14 streptococci. A single injection each week for 4 weeks gave good levels of antibody. Simultaneous immunization with three different types of group A streptococci resulted in production of antibodies against all three types.
