    • The invention relates to novel enzymes, which transfer sialic acid from a donor molecule onto an acceptor molecule (trans-sialidases). The enzymes are isolated from the protozoan Trypanosoma congolense. The invention also relates to functional equivalents of said enzymes, to the nucleic acid sequences and amino acid sequences that code for the enzymes and their functional equivalents, to expression constructs and vectors that contain said sequences, to recombinant microorganisms that carry the inventive coding nucleic-acid sequences, to a method for the recombinant production of the inventive enzymes, to a method for isolating said enzyme from Trypanosoma congolense, to a method for the enzymatic sialization of acceptor molecules using the inventive enzymes, to effectors of the inventive trans-sialidases, to the use of the nucleic acid sequences, amino acid sequences, enzymes, effectors or sialization products for producing vaccines, medicaments, foodstuffs or food additives, in addition to the latter products obtained by the inventive method.

    • 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.
