Description and significance
Astrovirus originated from ‘astron’, a Greek word for star because of the five-pointed or six-pointed side projection which can be detected by negative stained electron microscopy (EM). They were first described by Madeley & Cosgrove in 1975 as the causal for gastroenteritis in infants. Astrovirus disease is known as the causal for gastroenteritis, it is usually mild but more serious cases have been discovered in poultry. Astrovirus is most commonly found in turkeys and can lead to mortality. In 1980, turkey astrovirus was first described and was linked with turkey poults in the UK that were suffering from diarrhea and increased mortality. They were discovered in the U.S. the same year. Although replication is only routinely detected in the intestines, experimentally infected poults show thymus and bursal atrophy and the virus can be isolated in other tissues.
