VACCINE FOR RAISING IMMUNE RESPONSE TO VIRUS INDUCING SWINE RESPIRATORY AND GENITAL DISEASE, METHOD FOR PROTECTING PIG FROM DISEASE INDUCED BY THE VIRUS, PRODUCTION OF VACCINE FOR RAISING IMMUNE RESPONSE TO THE VIRUS, AND DNA OBTAINED FROM THE VIRUS

摘要

PURPOSE: To obtain a vaccine capable of enhancing immune response to diseases of hog respiratory organs and genital organs induced by virus so as to protect hogs. CONSTITUTION: This vaccine enhances the immune response to diseases induced by infection with virus (esp. PRRSV Iowa strain) capable of inducing diseases related to hog respiratory organs and genital organs (e.g. respective symptoms of II-type pulmonary cell formation, myocarditis, encephalitis, alveolar exudate formation, syncytia formation, and such symptoms as lethargy, dyspnea, forced breathing, a fever, rough fur, snore, cough and light interstitial hypertrophy). This vaccine can be administered intramuscularly, intracutaneously, intravenously, intraperitoneally, subcutaneously or intranasally. This vaccine is prepared from virus cultured in a cell line selected from the group consisting of PSP-36, PSP-36-SAH and MA-104.
