Abstract

The invention discloses a rabbit Eimeria medium precocious strain and its preparation method and application. The method comprises: obtaining sporulated oocysts of a virulent Eimeria rabbit medium strain through collection, separation and purification of rabbit feces, Infect the sporulated oocysts of the virulent strain of Eimeria mesocarpus in the weaned rabbits, and obtain the Nth generation Eimeria mesocarpa oocysts with shortened latent period, that is, the Eimeria mesocarpus oocysts. The precoccus mesicum strain; compared with the Eimeria mesocarpus strain in the field, the Eimeria mesocarpus precoccus strain prepared by the present invention is pure and has weak pathogenicity, and can be directly used to prepare vaccines and the preparation method of the rabbit Eimeria mesodium precoccus strain disclosed by the present invention is simple and easy to implement.

Description

technical field [0001] The invention relates to the application field of Eimeria, in particular to a rabbit Eimeria precoccus strain and its preparation method and application. Background technique [0002] Rabbit coccidiosis is a parasitic protozoan disease caused by one or more Eimeria coccidia of the genus Eimeria in the order Eucoccidia, Eimeriaceae, parasitizing in the liver, bile duct and intestinal tract of rabbits. The disease has brought great harm to the rabbit industry and seriously hindered the development of the rabbit industry. my country has listed it as a second-class animal disease, and it is also known as rabbit plague, rabbit brucellosis, and rabbit scabies. Four major rabbit diseases. According to reports, about 41.9% of rabbits in my country have been infected with coccidia, and the infection rate in Northwest, Northeast and Southwest of China has exceeded 60%. All breeds of rabbits are susceptible to the disease. Among them, the infection and disease o...
