The genus is distinguished on the basis of genetic characters.
No details are available on the morphology of virions.
Genome (Lau et al., 2014, Bullman et al., 2014): up to 9,874 nt (5′-UTR: up to 1,009 nt; ORF: up to 8,610; 3′-UTR: up to 308 nt). The 5′-UTR contains a predicted type II IRES. The location of the cre has not been identified.
Genome organization and replication
The deduced polyprotein has 2,855–2,870 amino acids. There is an L protein of unknown function. 1AB remains uncleaved. The 2A protein has an H-box/NC motif.
No virus has been isolated. Viral RNA was detected in faeces of chickens. Eight genetic types are distinguished by means of phylogenetic analysis.
Derivation of names
Sicinivirus: from Gaelic sicín, "chicken"
