[0018] Preparation method of hyperimmune Cryptosporidium beinii IgY antibody

[0019] 1. Preparation of immune antigen

[0020] 1. Amplification and purification of Cryptosporidium beinii oocysts The oocysts in the positive feces of a certain animal husbandry station in the urban area were collected. The oocysts were oblong and oval in shape. The measured oocyst size was 6.5 μm x 4.7 μm (5.4-7.8 μm x 4. 1~5.5μm) shape index 1.31, cleared chicken coccidia oocysts mixed with 3-day-old quail blindly, established an animal infection model in our laboratory and 18sRNA sequence comparison analysis, confirmed that it was Cryptosporidium bayeri (C .baileyi), the 3-day-old healthy chicks were used to subculture to amplify the oocysts of Cryptosporidium beinii in large quantities.

[0021] According to the method of Arrowood et al., the oocysts were purified by sucrose gradient centrifugation. Sucrose stock solution recipe: 500g sucrose, dissolved in 320mL distilled water, autoclaved ...

Abstract

The present invention provides yolk immunoglobulin preparation for preventing and treating cryptosporidiosis and health product of yolk immunoglobulin for strengthening immunity. The yolk immunoglobulin is prepared through the following steps: gathering cryptosporidium egg capsule from positive cryptosporidium excrement, separating, sucrose gradient centrifuging to purify cryptosporidium egg capsule and prepare cryptosporidium antigen, immunizing female laying fowl with the cryptosporidium antigen, collecting laid fowl egg, collecting yolk, diluting with distilled water, centrifuging to obtain supernatant, water diluting, and salting out with ammonium sulfate to obtain yolk immunoglobulin. The present invention is acted on the pathogen of cryptosporidiosis to reach specific inhibition.

Description

technical field [0001] The invention belongs to the field of biotechnology, relates to the technical field of aquatic animal breeding, and in particular relates to a kind of yolk immunoglobulin (IgY) for preventing and treating Cryptosporidiosis bainii and its application. Biological agents for primary diseases caused by sporozoites and health products for enhancing immune function. Background technique [0002] In 1907, Tyzzer discovered Cryptosporidium spp. for the first time in mouse mucosal tissue sections, and Cryptosporidiosis became a worldwide distributed zoonotic parasitic disease. The protozoan is widely parasitic on more than 180 species of humans and animals such as mammals, poultry, reptiles and amphibians, and can cause diarrhea in humans, especially fatal diarrhea in infants and young children and immunocompromised or deficient persons. Cause diarrhea and respiratory symptoms in livestock and poultry, resulting in decreased production performance or death. I...
