Research Progress on Detection Technologies of Avian Astrovirus
Avian astroviruses(AAstV)is a pathogen posing a serious danger to the health of poultry,which can cause turkey enteritis,chicken nephritis,duck hepatitis and gosling visceral gout,leading to slow growth,reduced hatchability and increased mortality.Pathogen detection plays an important role in the monitoring and differential diagnosis of AAstV infection,as no effective vaccines or drugs for AAstV infection are available.In the paper,the advantages and disadvantages of electron microscopy observation and other AAstV detection techniques,such as virus isolation and identification,immunofluorescence,ELISA and PCR,were reviewed,hoping to provide a reference for relevant personnel to select appropriate methods according to different occasions and needs.
