The genus is distinguished on the basis of genetic characters.
No details are available on the morphology of virions.
No details are available on physicochemical and physical properties.
Genome (Kapoor et al., 2008b): c. 6,700 nt (5′-UTR: 506 nt, ORF: 6,154 nt, 3′-UTR: 34 nt). The 5′-UTR contains a type IV IRES. The location of the cre has not been identified.
The deduced polyprotein is of 2,050 amino acids. There is no L protein. The 1AB protein remains uncleaved; 2A1 is a short FMDV-like polypeptide (NPG↓P) while the 2A2 protein has an unknown function. Two copies of 3B are predicted to be present.
No virus has been isolated. Known natural hosts are pinnipeds (Phoca vitulina, Pusa hispida) and black bears (Ursus thibetanus). Affected animals are apparently healthy. Two types are distinguished by means of phylogenetic analysis.
Aquamavirus: from aquatic mammal
There is only a single species in the genus.
