A polyvalent live vaccine for infectious bovine rhinotracheitis virus infection, bovine viral diarrhea-mucosal disease virus infection, parainfluenza 3 virus infection, bovine RS virus infection and bovine adeno 7 virus infection

摘要

A polyvalent live vaccine is composed of a mixture of 5 types of attenuated virus suspensions, including a virus suspension prepared by culturing attenuated infectious bovine rhinotracheitis (IBR) virus No. 758-43 strain in bovine or swine tissue cultures; a virus suspension prepared by culturing attenuated bovine viral diarrhea-mucosal disease (BVD-MD) virus No. 12-43 strain in bovine or swine tissue cultures; a virus suspension prepared by culturing attenuated parainfluenza 3 (PI3) virus BN-CE strain in chicken or bovine tissue cultures, or monkey kidney (vero) cells; a virus suspension prepared by culturing attenuated bovine RS virus rs-52 strain in hamster or bovine tissue cultures, or monkey kidney (vero) cells; and a virus suspension prepared by culturing attenuated bovine adeno 7 (AD7) virus TS-GT strain in goat or bovine tissue cultures, wherein said polyvalent live vaccine contains all the vaccines against infectious bovine rhinotracheitis, bovine viral diarrhea-mucosal disease, parainfluenza 3, bovine RS and bovine adeno 7, in order to achieve a greater efficiency of vaccination.
