BACTERIOPHAGE-BASE BIOPREPARATION FOR PROPHYLAXIS AND TREATMENT OF COLIBACILLOSIS (ESHCERICHIOSIS)IN ANIMALS Russian patent published in 2005 - IPC

FIELD: biotechnology, veterinary medicine.

SUBSTANCE: invention relates to the development of biological preparation for prophylaxis and treatment of colibacillosis (escherichiosis) and for control of carriage of escherichious infections pathogens in animals and poultries also. Also, invention can be used in producing curative fodders and ecologically pure human foodstuffs. Biopreparation for prophylaxis and treatment of escherichiosis in animals and poultries comprises strains of bacteriophages Phagum Escherichia coli Ec022-DEP and/or Phagum Escherichia coli Ec021-DEP, and/or Phagum Escherichia coli Ex0782-DEP, and/or Phagum Escherichia coli Ec0781-DEP, and/or Phagum Escherichia coli EPZ-1-DEP, and/or Phagum Escherichia coli EPZ-2-DEP, and/or Phagum Escherichia coli EG-5-DEP, and/or Phagum Escherichia coli BC-1-DEP, and/or Phagum Escherichia coli M78-DEP, and/or Phagum Escherichia coli Sheksna 2k-DEP taken in the effective amount. The biopreparation comprises also antiseptic, for example, quinosol and a stabilizing agent. Protein (for example, soybean protein), vegetable meal, organic polymer, milk, serum, albumin can be used as a stabilizing agent. Among organic polymers can be used: dextran, polyglucin, starch, polyvinylpyrrolidone. The biopreparation can be dried by lyophilization, granulated and placed in polymeric matrix. The biopreparation has no toxic properties on animals, it shows good hygroscopicity and can be good dispersed in water. The biopreparation can be used in liquid and dry prescription formulations and in different methods of its administrations: both by subcutaneous, intraperitoneal, intramuscular injections and as an aerosol, by administration of phage particles into lung compartments including applying as curative fodder and supplement to fodder, and by applying on surface of cutaneous integuments. Invention provides enhancing the effectiveness of treatment of animals and poultries with gastroenteric infections due to reducing treatment period, expanding spectrum of lytic effect of the biopreparation, resistance to effect of digestive tract enzymes and convenience in using.

EFFECT: valuable veterinary properties of biopreparation.
