Nidovirales is an order of enveloped, positive-strand RNA viruses which infect vertebrates and invertebrates. Host organisms include mammals, birds, reptiles, amphibians, fish, arthropods, molluscs, and helminths. [1] The order includes the families Coronaviridae, Arteriviridae, Roniviridae, Tobaniviridae, and Mesoniviridae.
Jul 30, 2008 · The order Nidovirales includes the families Coronaviridae, Roniviridae, and Arteriviridae (Figure 1). The Coronaviridae comprises two well-established genera, Coronavirus and Torovirus, and a tentative new genus, Bafinivirus. The Arteriviridae and Roniviridae include only one genus each, Arterivirus and Okavirus, respectively.

Apr 23, 2021 · At present, the order Nidovirales consists of 8 suborders including 109 species, which have a wide range of hosts from invertebrates (crustaceans and arthropods) to vertebrates (fishes, reptiles, amphibians, birds and mammals) (Saberi et al. 2018). Viral genome size and structure vary greatly among different suborders in the order Nidovirales.

Phylogenetically, Coronaviridae belongs to Nidovirales in group IV, with a single genomic RNA fragment, oriented in a positive direction. Nidovirales is an order that contains four families (Arteriviridae, Coronaviridae, Mesoniviridae, and Roniviridae) according to the genomic classification (Fig. 7.1) ( Cavanagh, 1997 ).

Severe acute respiratory syndrome coronavirus-2 (SARS-Cov-2) is a single-stranded positive-strand RNA virus that infects humans, birds, and some other vertebrates. It belongs to the Coronaviridae (CoV) family, Nidovirales order. CoVs are further divided into four categories: α, β, γ, and δ (Peck et al., 2015 ).
Feb 28, 2006 · Abstract. This review focuses on the monophyletic group of animal RNA viruses united in the order Nidovirales. The order includes the distantly related coronaviruses, toroviruses, and roniviruses, which possess the largest known RNA genomes (from 26 to 32 kb) and will therefore be called ‘large’ nidoviruses in this review.
