The genus is distinguished on the basis of genetic characters.
No details are available on the morphology of virions.
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.
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.
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.
Gallivirus: from the order Galliformes which contains turkeys and chickens; Latin gallina 'chicken'
