Picornaviridae

Genus: Potamipivirus


Genus: Potamipivirus

Virion

Morphology

No surface morphology of the icosahedral capsid is visible by EM.

Nucleic acid

Length of genome (Fichtner et al., 2013): c. 7,496 nt (partial) (5'-UTR: >488 nt; ORF: 6,777 nt; 3' UTR: 231 nt). The location of the cre has not been identified.

Genome organization and replication

Genome layout:

VPg+5'UTR[1AB-1C-1D-2A1npgp/2A2H-box/NC-2B-2C/3A-3B-3C-3D]3'UTR-poly(A)

The deduced polyprotein has a length of 2,259 aa. There is no L protein. 1AB protein remains uncleaved. 2A1 protein has a NPG↓P motif. 2A2 protein has a H-box/NC sequence motif.

Biology

Eel picornavirus (EPV) was isolated from a common eel (Anguilla anguilla) in Lake Constance on the river Rhine. EPV can be propagated in eel kidney 1 (EK-1) cells. It is pathogenic in experimentally infected glass eels and induces a high mortality.
