Virion

Morphology

Virus has not yet been isolated.

Nucleic acid

Length of genome (Li et al., 2009, Greninger et al., 2009, Holtz et al., 2009): 7,982-8,021 nt (5'-UTR: 709-763 nt; ORF: 7,110-7,125 nt; 3' UTR: 148 nt). The location of the cre has not been identified.

Genome organization and replication

Genome layout:

VPg+5'UTR^IRES-V[L/1AB-1C-1D/2A^H-Box/NC-2B-2C/3A-3B-3C-3D]3'UTR-poly(A)

The deduced polyprotein has a length of 2,374 amino acids. There is a L protein with unknown function. 1AB remains uncleaved. 2A protein has no H-box/NC sequence motif.

Antigenicity

See discussion under family description.

Biology

Viral RNA was detected in faeces of humans with gastroenteritis and non-polio acute flaccid paralysis and of chimpanzees. 

Species demarcation criteria

Within the single species Salivirus A, two genetic types are distinguished (Yu et al., 2015, Aldabbagh et al., 2015, Ng et al., 2012).

Member species

Virus names, the choice of exemplar isolates, and virus abbreviations, are not official ICTV designations.

Derivation of names

Sali: from stool aichi-like

These viruses have also been named klassevirus for kobu-like viruses associated with stool and sewage (Greninger et al., 2009).
