Genus: Oscivirus

Genus: Oscivirus


Nucleic acid

Length of genome (Woo et al., 2010): c. 7,640-7,678 nt (5'-UTR: 636-646 nt; ORF: 6,765-6,774 nt; 3' UTR: 238-256 nt). The location of the cre has not been identified.

Genome organization and replication

Genome layout:


The deduced polyprotein has a length of 2,255-2,258 aa. The genome encodes a L protein. 1AB remains uncleaved (with myristoylation signal). 2A protein has unknown function.


Viral RNA was detected in faeces of the oriental magpie robin (Copsychus saularis) and the grey-backed thrush (Turdus hortulorum). Two genetic virus types are defined.
