Research Article: Rapid detection of goose astrovirus genotypes 2 using real-time reverse transcription recombinase polymerase amplification
Abstract:
Goose astrovirus (GoAstV) is an important pathogen that causes joint and visceral gout in goslings. It has been circulating in many provinces of China since 2017. Goose astrovirus genotypes 2 (GoAstV-2) is the main epidemic strain, and its high morbidity and mortality have caused huge economic losses to the goose industry. An accurate point-of-care detection for GoAstV-2 is of great significance. In this study, we developed a real-time reverse transcription recombinase polymerase amplification (RT-RPA) method for the on-site detection of GoAstV-2 infection.
Introduction:
Astroviruses are small, single-stranded, nonenveloped RNA viruses of the family Astroviridae that cause multiple illnesses, including gastroenteritis and diarrhea in humans, poor feed conversion and growth inhibition in turkeys, hepatitis in ducklings, and short stature syndrome and nephritis in chickens and pigeons [1,2,3]. According to the different species of origin, Astroviridae is classified into Mamastrovirus and Avastrovirus, which infect mammalian and avian species, respectively [4]. The Avastrovirus genus…
