RESUMO
The infectious bursal disease virus is not enveloped and has a diameter of 60 nm and a density of about 1.32 g/ml. It contains two pieces of single-stranded RNA with molecular weights close to 2 X 10(6). The capsid is made up of four major polypeptides with molecular weights of 110,000, 50,000, 35,000, and 25,000. The virus replicates in chicken embryo fibroblasts rather than in epitheloid cells. After an eclipse period of 4 h, virus production reaches a maximum about 12 h later. The virus has no structural or biological similarities with defined avian reoviruses, and it cannot be classified in one of the established taxonomic groups.
