Arnidovirineae Explained

Arnidovirineae is a suborder of viruses in the order Nidovirales. There are 4 families and 16 genera in the Arnidovirineae suborder.^[1]

Hosts

For species that fall under the Arnidovirineae suborder, large mammals serve as natural hosts, with sizes varying from mice to boars and horses. However, for 3 genera snakes and turtles serve as natural hosts.

Genome

Viruses in this suborder have relatively small genomes compared to other suborders in the Nidovirales order, ranging from 12-16kb. These genome differences are the primary identifying factor of the suborder. Species of Arnidovirneae have been found all around the world.^[2]
