Abstract:
A new vaccine to duck hepatitis virus is provided to have excellence in resistance against epidemic duck hepatitis and lessen damage caused by the duck hepatitis. A method for producing vaccine(deposition No. KCCM10883P) of duck hepatitis virus having sequence of sequence No. 1 [SEQ ID NO:1] comprises: a step of diluting recently epidemic duck hepatitis virus in phosphate buffer; a step of inoculating 7-9 days old chicken embryo; a step of culturing the inoculated chicken embryo at 37°C for three days; and a step of collecting the cultured chicken embryo and performing subculture sequencially to adapt the chicken embryo. A process for manufacturing a new vaccine is performed with: the step of attenuating the duck hepatitis virus; a step of testing restoration of attenuated virus; a step of searching defense ability of vaccine to selected duck hepatitis virus; a step of searching defense ability in each pathway; a step of searching minimum amount of the vaccine; and a step of safety and amount of the vaccine.
Abstract:
A riemerella vaccine for preventing riemerella infection is provided to defend the infection of field pathogenic Riemerella anatipestifer which occurs frequently in a country and prevent ducks from being perished by the riemerella infection, thereby minimizing economical loss of a duck industry. A riemerella vaccine for preventing riemerella infection comprises an inactivated Riemerella anatipestifer and an immuno-enhancing agent, wherein the inactivated Riemerella anatipestifer is a strain selected from the group consisting of serovar type I, serovar type IV, serovar type VII, serovar type XVI and a mixture strain thereof. A method for preparing the riemerella vaccine comprises the steps of: (a) culturing Riemerella anatipestifer isolated from a suck; (b) adding an inactivating agent such as 0.3% formalized physiological saline solution(FPSS) to a culture solution obtained from the step(a) to inactivate the Riemerella anatipestifer; and (c) adding an immuno-enhancing agent to the inactivated Riemerella anatipestifer culture solution to prepare a mixture vaccine. Further, the immuno-enhancing agent is ISA70.
Abstract:
PURPOSE: A composition containing Taraxacum officinale extract is provided to suppress BSE-modified prion production or remove the prion and to prevent or treat BSE. CONSTITUTION: A veterinary composition for preventing or treating BSE contains Taraxacum officinale extract.

The extract is prepared using water, low carbon number alcohol of C1-C4, and a mixture solvent thereof. A feed additive composition for preventing or treating BSE contains the extract.
Abstract:
PURPOSE: A monoclonal antibody for specifically detecting abnormal prion of spongiform encephalopathy is provided. CONSTITUTION: A fusion cell line of deposit number KCLRF-BP-00213 produces monoclonal antibody for detecting abnormal prion of spongiform encephalopathy. A method for preparing fusion cell line comprises: a step of inoculating a peptide of sequence number 1 to a knock-out mouse; a step of isolating B cells from the mouse; and a step of fusing the B cells and mouse myeloma-derived cells. The abnormal prion of spongiform encephalopathy is detected by western blotting using the monoclonal antibody.
Abstract:
The present invention relates to an expression vector comprising a gene encoding a prion protein of Capra hircus and a cell transduced by the vector. The present invention can be used for manufacturing a cell having polymorphism, which represents Capra hircus bred in Korea, and a transduced mouse; and can be effectively used for developing an animal experimental model for studies including diagnosis of prion diseases which include scrapie occurred in goat family animals, and for confirming if domestic TSE diseases interspecifically spread or not.
Abstract:
PURPOSE: A composition containing Rubi Fructus extract is provided to inhibit modified prion production and to prevent or treat BSE.
