Immunoelectrophoresis revealed in phenol extracts from S. faecalis and S. faecium a mixture of free and lipid-bound teichoic acids, both reactive with Group D antisera. In phenol extracts from S. suis only lipid-bound teichoic acid, also reactive with Group D antiserum, was seen. This difference probably accounts for the low yield of Group D antigen from S. suis as compared with S. faecalis and S. faecium when heating at pH 2 is used for extraction. When phenol is used good yields are obtained from S. suis as well as from S. faecalis and S. faecium. Lipoteichoic acids from S. faecalis and S. faecium have a backbone structure the same as or similar to that of Group A streptococcal teichoic acid. Lipoteichoic acid from S. suis has a structure differing from that of S. faecalis and S. faecium, e.g., possibly in the attachment of its glucosyl substituents. Precipitation reactions between S. suis lipoteichoic acid and Group D antisera were specifically inhibited by glucose. Reactions between S. bovis phenol extracts and some Group D antisera were also specifically inhibited by glucose, but extracts from S. faecalis and S. faecium were not. This may indicate a monosaccharide glucosyl substituent in teichoic acid from S. suis and S. bovis instead of the di- or trisaccharide previously postulated as the glucosyl substituent in the teichoic acid of S. faecalis.

In 1899, Thiercilin used the term “enterococcus” to describe microscopic organisms seen in pairs or short chains in feces. Later (in the 1930s) the name was used in a more restrictive sense for streptococci that had the hardy capacity to survive under extreme conditions.Enterococci belong to a group D family of streptococci, as characterized by Lancefield in 1938. In contrast to other groups of streptococci, the group D antigen is not a wall carbohydrate but a glycerol teichoic acid containing glucose and D-alanine. This antigen appears to be related directly to the cytoplasm or plasma membrane.

Abstract The D antigen content of nucleated red cell precursors in human bone marrow was estimated using autoradiography and 125I-anti-D. D antigen first appeared in the pronormoblast, and the quantity of antigen progressively increased during red cell maturation. Maximal anti-D binding occurred on mature red blood cells. Pronormoblasts, basophilic normoblasts, polychromatophilic normoblasts, and orthochromatic normoblasts, respectively, had approximately 1/4, 1/2, 2/3, and 3/4 the quantity of antigen found on mature red cells. None of the other cell types were found in bone marrow labeled with anti-D.

Cell walls of strains of Lactobacillus plantarum lacking the group D precipitinogen (a glucosylribitol teichoic acid) contain glucosylglycerol teichoic acid in which the glycosidic substituents are attached to the primary hydroxyl group of glycerol. Three distinct repeating units have been isolated from the teichoic acid preparation of strain C106, indicating either that the polymer is complex or that the wall contains a mixture of teichoic acids. Walls of streptobacteria differ from those of L. plantarum and contain neither teichoic acid nor diaminopimelic acid.
