METHOD FOR DELIVERING BIOLOGICALLY ACTIVE COMPOUND ONTO MUCOSA-ASSOCIATED LYMPHORETICULAR ANIMAL TISSUE, METHOD FOR OBTAINING COMPOSITION AND COMPOSITION FOR DELIVERING BIOLOGICALLY ACTIVE COMPOUND Russian patent published in 2005 - IPC

FIELD: veterinary science.

SUBSTANCE: the suggested methods and compositions provide transfer of biologically active compound, antigen predominantly, in animal body. Efficient quantity of biologically active compound should be put into microcapsules made of biocompatible material the size of which do not exceed 10 mcm, then one should introduce efficient quantity of these microcapsules, perorally, preferably, for animals under immunization. As material for microcapsules one usually applies a biologically active polymer or copolymer being of capacity to pass through gastro-intestinal tract or being localized at mucosal surface not being affected by biodegradation. This provides the transfer of biologically active compound onto Peyer's patches or other mucosa-associated lymphatic tissues, that provides inducing systemic immunity and activization of mucosal immunity system.

EFFECT: higher efficiency.
