The rabies virus belongs to the family of elasmoviridae and the genus rabies virus, which is bullet-shaped, spiral symmetrical, with an envelope on the surface, containing single-stranded DNA, and is the pathogen that causes rabies. The rabies virus has two main antigens, one is the glycoprotein antigen on the outer membrane of the virus, which can bind to acetylcholine receptors, making the virus neurotoxic, and causing the body to produce neutralizing antibodies and hemagglutination inhibiting antibodies to neutralize antibodies, which has a protective effect. The other is the nucleoprotein antigen on the inner layer, which causes the body to produce complement-binding antibodies and precipitins without protective effect. Rabies is a zoonotic infection caused by the rabies virus, for which a rabies vaccine was discovered by French scientists long before the virus was discovered in 1884.
