Abstract:
A low pathogenic avian influenza viral vaccine for preventing H5 subtype avian influenza viral infection is provided to enhance safety and medicinal efficacy of use, and prevent the infection of H5N1 type high pathogenic avian influenza virus safely. The method for preparing the low pathogenic avian influenza viral vaccine for preventing H5 subtype avian influenza viral infection comprises the steps of: (1) culturing a A/wild bird feces/Korea/CSM-2/02(H5N3) strain in a specific pathogen free egg(SPF egg) for 72 hours and collecting allantoic fluid; (2) measuring the titrate of the virus collected in step(1) through hemagglutination inhibition test; (3) concentrating the virus 10 times by centrifuging the virus at 18,000 rpm for 3 hours; (4) attenuating the virus by treating the concentrated virus with 0.1% formalin at 20 deg.C for 12 hours; and (5) mixing the attenuated virus solution with oil adjuvant ISA70 in a weight ratio of 3:7, wherein the low pathogenic avian influenza viral vaccine contains at least one protein encoded by the gene of SEQ ID NO:2 to SEQ ID NO:9.

Abstract:
PURPOSE: An H9 type avian influenza virus diagnosis kit by quick immunochromatography is provided to ensure quick and simple diagnosis without special equipment. CONSTITUTION: A kit for diagnosing H9 type avian influenza virus contains monoclonal antibodies. The monoclonal antibody is prepared from hybridoma cells of deposit number 11753BP, KCTC 11754BP, and KCTC 11755BP. A H9 type avian influenza diagnosis strip contains the monoclonal antibody. The diagnosis strip comprises a sample pad(1), a gold pad(2), nitrocellulose membrane(3), and moisture absorption pad(4). The gold pad contains a gold conjugate in which gold particles are conjugated with a monoclonal antibody produced from hybridoma cells of deposit number KCTC 11755BP.
