Abstract

The invention relates to a combined inactivate vaccine for sheep pox and contagious caprine pleuropneumonia (CCPP), and a production method of the combined inactivate vaccine. The method comprises thesteps of inoculating suspension cultured BHK-21 cells and a proper culture medium with a capripox virus AV41 strain and a mycoplasma capricolum pneumonia subspecies C87001 strain respectively for culturing, harvesting the culture, concentrating and purifying; inactivating with BEI and thimerosal respectively, adding a suitable adjuvant according to a certain proportion, mixing and emulsifying. The combined inactivate vaccine is used for preventing the sheep pox and the CCPP. The combined inactivate vaccine, provided by the invention, for the sheep pox and the CCPP is obtained internationallyfor the first time, and can achieve the aim of preventing the two diseases by means of one injection; furthermore, a live vaccine for the sheep pox is produced by means of the suspension cultured BHK-21 cells; compared with the original inactivate vaccine prepared from ovine testicular cells, the combined inactivate vaccine provided by the invention has obvious advantages, and can solve the problems that in the production process of the live vaccine for the sheep pox, the sheet testis is difficult to obtain, lamb death and ewe abortion are easily caused, subcutaneous immunization needs to be performed when the vaccine is used, an operation is difficult during clinical application, and the like.
