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 · Nidoviruses form a phylogenetically compact but diverse group of enveloped positive-stranded RNA viruses with the largest RNA genome known. They infect a broad range of hosts, including humans, other mammals, birds, fish, and shrimp. Nidovirus infection starts by binding to a receptor on the cell surface, and fusion of the viral and cellular ...

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.

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.

It lies within the lineage C of the genus Betacoronavirus (CoV) in the family Coronaviridae under the order Nidovirales. It has close phylogenetic proximity to two bat coronaviruses, Tylonycteris bat CoV HKU4 (Ty-BatCoV-HKU4) and Pipistrellus bat CoV HKU5 (Pi-BatCoV-HKU5). Like the other coronaviruses, it is an enveloped single-stranded RNA ...
Jul 2, 2020 · The order Nidovirales is a monophyletic group of animal RNA viruses. This group can be divided into the six distinct families of Arteriviridae, Coronaviridae, Mesnidovirineae, Mononiviridae, Ronidovirineae, and Tobaniviridae. All known Nidovirales have single-stranded, polycistronic RNA genomes of positive polarity (Modrow et al., 2013).
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 ).
