31 Jul 2008
Abstract excerpt
Coronaviruses are positive-strand RNA viruses of extraordinary genetic complexity and diversity. In addition to a common set of genes for replicase and structural proteins, each coronavirus may carry multiple group-specific genes apparently acquired through relatively recent heterologous recombination events. Here we describe an accessory gene, ORF3, unique to canine coronavirus type I (CCoV-I) and characterize...
