Summary:In one aspect, the invention relates to an immunogenic composition comprising modified O-polysaccharide molecules derived from E. coli lipopolysaccharides and conjugates thereof. Multivalent vaccines may be prepared by combining two or more monovalent immunogenic compositions for different E. coli serotypes. In one embodiment, the modified O-polysaccharide molecules are produced by a recombinant bacterium that includes a wzz gene. Selon un aspect, l'invention concerne une composition immunogène comprenant des molécules O-polysaccharidiques modifiées dérivées de lipopolysaccharides d'E. coli et des conjugués associés. Des vaccins multivalents peuvent être préparés en combinant au moins deux compositions immunogènes monovalentes pour différents sérotypes d'E. coli. Dans un mode de réalisation, les molécules O-polysaccharidiques modifiées sont produites par une bactérie recombinée qui comprend un gène wzz.
