Salmonella typhimurium infected with the plasmid ColIb drd2 gave rise to changes in the composition of the bacterial lipopolysaccharide. Bacteria carrying the wild-type ColIb, the revertant of drd2 to the wild type, or the noncolicinogenic strain resulting from the elimination of ColIb drd2, showed no changes in the sugar composition of the lipopolysaccharide. The structure of the O-specific side chains of the lipopolysaccharide produced by S. typhimurium 902, infected with derepressed ColIb mutants has been investigated. As a result of these studies, it is proposed that the O-specific side chains are composed of chemical repeating units with the following structure: (formula: see text).

UI MeSH Term Description Entries
D008070 Lipopolysaccharides Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed) Lipopolysaccharide,Lipoglycans
D002240 Carbohydrate Sequence The sequence of carbohydrates within POLYSACCHARIDES; GLYCOPROTEINS; and GLYCOLIPIDS. Carbohydrate Sequences,Sequence, Carbohydrate,Sequences, Carbohydrate
D012486 Salmonella typhimurium A serotype of Salmonella enterica that is a frequent agent of Salmonella gastroenteritis in humans. It also causes PARATYPHOID FEVER. Salmonella typhimurium LT2
