Teichoic Acids and Group Antigens in Lactobacilli

Abstract

SUMMARY: Purified teichoic acids and extracts with group-specific activity have been examined with specific antisera for a number of lactobacilli. The wall teichoic acids from groups D and E lactobacilli have been identified as the group-specific substances, whereas in group A the intracellular teichoic acid showed group-specificity. It is possible that group-specificity is associated with intracellular teichoic acid in group F.
