The genus is distinguished on the basis of genetic characters.
No surface morphology of the icosahedral capsid is visible by EM.
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.
The deduced polyprotein is 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.
See discussion under family description.
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.
There is only a single species in the genus.
Potamipi-: from Greek potamos, 'river', and picornavirus
