Abstract

The invention discloses a test strip for quickly detecting a swine Japanese encephalitis antibody and a preparation method of the test strip. The test strip consists of absorbent paper, a nitrocellulose membrane, a glass cellulose membrane, a sample pad and a support object, wherein the nitrocellulose membrane contains a detection line coated by JEV E protein and a control line coated by a goat anti-JEV antibody; and the glass cellulose membrane is combined with colloidal gold marked JEV E protein. According to the invention, by adopting a membrane chromatography indirect sandwich method, a specific antibody in Japanese encephalitis immune pig or infected pig serum can be detected. When detecting a swine Japanese encephalitis antibody, the test strip disclosed by the invention is simple, convenient and quick to operate, special instrument or professional training is not required, and the result is clear and easy to distinguish; and the test strip is easy to popularize and particularly suitable for base field test and epidemiological investigation, and plays an important auxiliary role in the diagnosis of swine Japanese encephalitis.

Description

technical field [0001] The invention belongs to the technical field of detecting porcine Japanese encephalitis, in particular to a test strip for rapid detection of porcine Japanese encephalitis antibody and a preparation method thereof. Background technique [0002] Japanese encephalitis B (Japanese encephalitis B, JE), also known as epidemic Japanese encephalitis, Japanese encephalitis, referred to as Japanese encephalitis, is a kind of disease caused by Japanese encephalitis virus (Japanese encephalitis virus, JEV). Zoonotic mosquito-borne natural foci of infectious diseases. The disease is very harmful to humans and is one of the most common vector-borne diseases of the human central nervous system, which can cause death of patients and often leave serious neurological sequelae. Among animals, pigs are the main source of infection of JE, which can amplify JEV, and JEV infection generally takes the form of a pig-mosquito-human chain. JE can cause miscarriage, stillbirth...
