technical field

[0001] The invention discloses a method for preparing Eimeria oocysts in batches, and relates to a method for separating and purifying oocysts (antigens) for producing Eimeria chicken vaccines. Background technique

[0002] About chicken Eimeria coccidiosis

[0003] Eimeria (Eimeria) coccidium (Coccidium) is a class of obligate parasitic protozoa that parasitizes in chicken intestines, causing chicken coccidiosis (Coccidiosis). According to statistics, there are 15 kinds of chicken coccidia reported in the whole world, wherein, 5 kinds have obvious pathogenicity, they are: Eimeria tenella (E.tenella), poisonous Eimeria (E. tenella) .necatrix), E.maxima, E.acervulina, and E.mitis. Among the 5 pathogenic coccidia, 3 are harmful to chicks: Eimeria tenella, Eimeria giga, and Eimeria spp.

[0004] Coccidiosis is a ubiquitous infectious disease. Where there are chickens in the world, there will be chicken coccidiosis, and there will be coccidiosis. Large-scale c...
