Abstract: An oligosaccharide mixture based on oligosaccharides from one or several animal milks composed of two or more monosaccharide units. The oligosaccharide mixture comprises at least two oligosaccharide fractions which are each composed of at least two different oligosaccharides. Lactose does not pertain thereto and the total spectrum of the oligosaccharides in the oligosaccharide mixture differs from those present in animal milk or animal milks, wherefrom the oligosaccharide fractions are extracted and that a) if the oligosaccharides are extracted from only one animal milk, the proportion of neutral oligosaccharides to acidic oligosaccharides is 90-60:10-40 weight %, or b) if the oligosaccharides are extracted from at least two animal milks, the oligosaccharides extracted from two different animal milks each make up 10 weight % of the total amount of oligosaccharides present in the oligosaccharide mixture. The oligosaccharide mixture approximates human milk with respect to its positive properties.

Abstract: 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 ? 1-3 or ? 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.

Abstract: Described is the use of in particular homopolymer cycloglycans having a ring-shaped base structure of 2 to 40 monosaccharides in the ring, for preventing the invasion and infection of mammal cells by pathogens, and for combating diseases caused by such pathogens, and food compositions, dietetic compositions and pharmaceutical compositions containing these cycloglycans.

Abstract: The invention relates to the use of sialic carbohydrates of general formula (I), containing at least one carbohydrate unit of general formula (II) for the immune modulation, immune suppression and in the prevention and treatment of infections in humans and animals.

Abstract: The invention relates to an oligosaccharide mixture based on oligosaccharides produced from one or several animal milks and which are composed of two or more monosaccharide units. Said oligosaccharide mixture is characterized in that it comprises at least two oligosaccharide fractions which are each composed of at least two different oligosaccharides.
