Genus: Gallivirus


Genus: Gallivirus

Distinguishing features

The genus is distinguished on the basis of genetic characters.

Virion

Morphology

No details are available on the morphology of virions.

Nucleic acid

Genome (Lau et al., 2014, Boros et al., 2012a): c. 8,500 nt (5′-UTR: 761 nt; ORF: 7,425 nt; 3′-UTR: 310 nt). 5′-UTR contains a type II IRES. The 3′-UTR is 310 nt. The location of the cre has not been identified.

Genome organization and replication

Genome layout:

VPg+5′-UTRIRES-II-[L-1AB-1C-1D/2AH-box/NC-2B-2C/3A-3B-3C-3D]-3′-UTR-poly(A)

The deduced polyprotein is of 2,474 aa. There is an L protein with unknown function. The 1AB protein remains uncleaved. The 2A protein contains an H-box/NC motif. 

Biology

No virus has been isolated. Viral RNA was detected in the faeces of turkeys and chickens. Two genetic types are distinguished by means of phylogenetic analysis.

Derivation of names

Gallivirus: from the order Galliformes which contains turkeys and chickens; Latin gallina 'chicken'

Species demarcation criteria
