ICTV Virus Taxonomy Profile: Amnoonviridae 2023

Area of Science:

• Virology
• Infectious Diseases
• Genomics

Background:

• Amnoonviridae is a family of negative-sense RNA viruses.
• These viruses infect fish and possess segmented genomes.
• The International Committee on Taxonomy of Viruses (ICTV) provides taxonomic reports.

Purpose of the Study:

• To summarize the ICTV report on the Amnoonviridae family.
• To provide an overview of the genomic structure and key proteins of Amnoonviridae.
• To highlight the taxonomic classification of these fish-infecting viruses.

Main Methods:

• Review and summarization of the official ICTV report on Amnoonviridae.
• Analysis of the genomic composition, including genome size and segmentation.
• Identification of open reading frames (ORFs) and their encoded proteins.

Main Results:

• Amnoonviridae genomes are approximately 10.3 kb and consist of 10 segments.
• Each segment contains at least one open reading frame (ORF).
• Specific ORFs (RNA1-3) encode viral polymerase subunits, and RNA4 encodes a nucleoprotein.

Conclusions:

• The Amnoonviridae family represents a distinct group of fish viruses with segmented negative-sense RNA genomes.
• The genomic organization facilitates the replication machinery, including polymerase and nucleoprotein synthesis.
• This summary provides a concise overview of the current taxonomic understanding of Amnoonviridae based on the ICTV report.
