Abstract: Pseudorabies，also called Aujeszky 's disease，is a highly contagious disease caused by pseudorabies virus (PRV). In the absence of a specific host，pseudorabies virus can invade the body of a variety of mammals， including pigs，cattle，sheep，etc.，which leads to severe clinical symptoms and acute death in susceptible animals. The existence of porcine pseudorabies was first reported in China in the 1950s，and since 2011，new porcine pseudorabies variants have emerged in some areas，resulting in serious economic losses to the pig industry. Although scientists have been working on the design of diagnostic methods and the development of related vaccines， pseudorabies is still widespread in the pig industry，and its discovery in recent years that it also has potential problems for human health has aroused strong concern in the world. At present，pseudorabies vaccine is widely immunized in pig farms in China，so it is very important to detect the antibody level produced by the vaccine after immunization. In this paper，the current antibody detection methods for PRV will be summarized，and their advantages anddisadvantages will be compared and analyzed in order to provide a reference for the selection of antibody detection methods on pig farms.
