Abstract

SUMMARY: The K antigen of B41 was isolated by isoelectric precipitation from heated bacterial suspensions. Chromatography and immunoabsorption experiments suggested that the mannose-resistant haemagglutinating activity of partially purified preparations of antigen was K. The antigen was partially susceptible to bacterial proteases and was inactivated by periodate oxidation. Haemagglutination inhibition experiments with sugars and absorption of K with antisera to human blood groups A and B substances suggested that K contains a terminal α-linked -acetylgalactosamine moiety, which is involved in the haemagglutination reaction, and an adjacent terminal α-linked galactose moiety, which plays no part in the reaction.
