Enterobacterial common antigen

The first heteropolysaccharide for which a cyclic structure has been proposed is the enterobacterial common antigen (ECA), which was shown by f.a.b.-m.s. to be a mixture of three cyclic components containing 4, 5, and 6 repeats, respectively, of a previously characterized trisaccharide (31) in which the GlcNAc residues were known to be partially acetylated at 0-6. [Pg.69]

Thus, lipopolysaccharides are potent pyrogens in man and rabbits. Furthermore, they are mitogens for B-lymphocytes (mouse) and they induce lethal toxicity in various experimental animals (.7). The lipoprotein (IS. coli) is also a B-cell mitogen it is, however, devoid of pyrogenicity and lethal toxicity (6). K-antigens and the enterobacterial common antigen lack all of these latter activities. [Pg.195]

Finally, a synthesis of the determinant of the enterobacterial common antigen which is not a true O-antigen has been reported [101],... [Pg.8]

Lipopolysaccharides.— Recent reviews have dealt with the compositions and the structures of bacterial lipopolysaccharides/ the serological properties, chemistry, and genetics of the O antigens from E. coli, the enterobacterial common antigen, the involvement of lipids in the biosynthesis of lipopolysaccharides, and the binding of bacteriophages to O antigens. ... [Pg.275]

Enterobacterial common antigen is a common component shared by almost all wild-type strains of Enterobacteriaceae. It has been isolated fi om Salmonella montevideo and found to be a linear polymer of l->-4-linked A-acetyl-D-glucosamine and iV-acetyl-D-mannosaminuronic acid, esterified to a limited extent by palmitic and acetic acids. These components accoimt for about 70 per cent of the molecule, with an... [Pg.111]

Enterobacterial Common Antigen (ECA). This envelope antigen common among many different genera of enterobacteria has received relatively little attention considering the potential diagnostic and prophylactic value of a common bacterial antigen. ECA can be detected in bacterial extracts by... [Pg.174]
