Immunochemistry of O and R antigens of Salmonella and related Enterobacteriaceae.

“…mannose (I) linkage following abequose or from the change of the same linkage (II) preceding abequose. The chemical data rule out the first hypothesis of a change of linkage between man-involved in conversion with phage 27 could be nose and rhamnose (220) or of the anomeric explained by a change in enzyme equipment which position of rhamnose (221).…”

“…R mutants also produce endotoxins, which are closely associated with the R-antigenic complex (29,30,145,171,172,221,253). However, these strains are avirulent, and can be phagocytized much more easily than the wild strains (199,201).…”

Immunochemistry of Shigella flexneri O-antigens: a study of structural and genetic aspects of the biosynthesis of cell-surface antigens.

“…With the S. flexneri, in which the O-specific side chains contain the same hexose constituents-namely, D-glucose, N-acetyl-D-glucosamine, and L-rhamnose-type specificity is determined by unique linkages between these residues and cross-reactivity by the sharing of common structural sequences (40,92,93,96). As these side chains comprise the greater bulk of the total molecule, they were assumed to contain a number of identical repeating units (95) analogous to those proposed for Salmonella groups B, D, E, G, N, and U (55,81,99,100,106). As will be shown, there is now much structural evidence that this assumption was correct.…”
