    摘要: Neutral straight-chain or branched oligosaccharides for preventing the invasion and infection of mammal cells by pathogens and for fighting diseases caused by such pathogens are disclosed. Food, dietetic products and pharmaceutical agents containing oligosaccharides consist of a base unit of formula (I), and between 0 and 19 other units of formula (II), which are linked directly or indirectly to the base unit. Gal represents a galactose monosaccharide unit; Glc represents a glucose monosaccharide unit; HexNAc rpresents an N-acetylated galactosamine or glucosamine monosaccharide unit (GalNAc or GlcNAc); R independently represent a β 1-3 or β 1-6 glycosidic link to HexNAc monosaccharide of the next [Gal-HexNAc] unit (II), and on a terminal [Gal-HexNAc] unit, or R are not present; and a terminal [Gal-HexNAc] unit, wherein R represent a deoxyhexose radical, can have another deoxyhexose radical on the HexNAc monosaccharide unit.
