Astroviruses (Astroviridae) are a type of virus that was first discovered in 1975 using electron microscopes following an outbreak of diarrhea in humans.[1] In addition to humans, astroviruses have now been isolated from numerous mammalian animal species (and are classified as genus Mamastrovirus) and from avian species such as ducks, chickens, and turkey poults (classified as genus Avastrovirus). Astroviruses are 28–35 nm diameter, icosahedral viruses that have a characteristic five- or six-pointed star-like surface structure when viewed by electron microscopy. Along with the Picornaviridae and the Caliciviridae, the Astroviridae comprise a third family of nonenveloped viruses whose genome is composed of plus-sense, single-stranded RNA.[2] Astrovirus has a non-segmented, single stranded, positive sense RNA genome within a non-enveloped icosahedral capsid.[3] Human astroviruses have been shown in numerous studies to be an important cause of gastroenteritis in young children worldwide.[2] In animals, Astroviruses also cause infection of the gastrointestinal tract but may also result in encephalitis (humans and cattle), hepatitis (avian) and nephritis (avian).[4]
