Clinical symptoms, associated with IBV infection, may be assessed 3-10 days post-infection. IBV has a 27.6 kb RNA genome and like all coronaviruses contains the four structural proteins; spike glycoprotein (S), small membrane protein (E), integral membrane protein (M) and nucleocapsid protein (N) which interacts with the genomic RNA. full-length genome GGTTAATCTTAGATCATGGACCAAAACACATCTTAACGTGTGTTAGGTGCGTGATTTTGT TCTATTAGGTACTCCTTTTGTGGTAATGGACGACATGTTCTAACCATACCGCAAAATGCA Coronaviruses are divided into four groups, as shown below: The variant replicase gene of the coronavirus of the present invention may be derived from an alphacoronavirus such as TGEV; a betacoronavirus such as MHV; or a gammacoronavirus such as IBV. 7 The recombinant vaccinia virus (rVV) may be made using a vaccinia-virus based reverse genetics system.
