Articulavirales Explained

Articulavirales is an order of segmented negative-strand RNA viruses which infect invertebrates and vertebrates.^[1] It includes the family of influenza viruses which infect humans. It is the only order of viruses in the monotypic class Insthoviricetes. The order contains two families and eight genera. Metatranscriptomics of aquatic animal samples paired with phylogenetics suggests that Articulavirales exhibits complex cross-species virus transmission and virus-host co-divergence over deep evolutionary time scales. Potentially originating in ancient aquatic animals at least 600 Mya.^[2]

Etymology

The order name Articulavirales derives from Latin Latin: articulata meaning "segmented" (alluding to the segmented genome of member viruses) added to the suffix for virus orders -virales.^[3] The class name Insthoviricetes is a portmanteau of member viruses "influenza, isavirus, and thogotovirus" added to the suffix -viricetes for virus classes.

Genome

Member viruses have segmented, negative-sense, single-stranded RNA genomes.

Classification

The order Articulavirales contains two families and eight genera:

• Amnoonviridae
  • Tilapinevirus
• Orthomyxoviridae
  • Alphainfluenzavirus
  • Betainfluenzavirus
  • Deltainfluenzavirus
  • Gammainfluenzavirus
  • Isavirus
  • Quaranjavirus
  • Thogotovirus
