Genus: Fipivirus

Genus: Fipivirus

Distinguishing features

The genus is distinguished on the basis of genetic characters.



No details are available on the morphology of virions.

Nucleic acid

Genome (Shi et al., 2018): c. 7,790–8,173 nt (5′-UTR: up to 665 nt; ORF: 6,861–7,206 nt; 3′-UTR: 246–401 nt). The location of the cre has not been identified.

Genome organization and replication

Genome layout:


The deduced polyprotein is of 2,287–2,402 amino acids. There is no L protein. The 2A protein has an H-box/NC sequence motif.


No virus has been isolated. Viral RNA was detected in organ pools (gut, liver, gill) of various captured fresh water and sea water fishes.

Derivation of names

Fipivirus: derived from fish picornavirus

Species demarcation criteria

Members of a species of the genus Fipivirus:

  • are less than 40% divergent in polyprotein amino acid sequence
  • are less than 50% divergent in P1 amino acid sequence
  • are less than 50% divergent in 2C+3CD amino acid sequence
  • share a common genome organization
  • share a natural host range
