RESUMO

Human astrovirus is an important cause of acute gastroenteritis. We have generated, for the first time, a vaccinia virus recombinant expressing the astrovirus 87-kDa structural polyprotein. The results demonstrate that this expression results in the formation of virus-like particles in the absence of other astrovirus proteins and genomic RNA. The purified trypsin-activated virus-like particles strongly resemble the complete astrovirus particles.
