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. The order includes the families Coronaviridae, Arteriviridae, Roniviridae, Tobaniviridae, and Mesoniviridae.
A vírus szubmikroszkopikus biológiai organizmus, amely nem sejtes szerveződésű és csak parazitaként az élőlények sejtjeiben képes szaporodni. Minden életformának, növényeknek, állatoknak, gombáknak, egysejtű eukariótáknak és baktériumoknak megvannak a vírusos fertőzéseik. [1]
The members of the order Nidovirales are enveloped, positive-strand RNA viruses of widely different architecture. Depending on whether the external appearance of the virion or the nucleocapsid is considered, similarities and differences can be discerned (Figure 1).
Jul 30, 2008 · 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 membranes mediated by one of the major surface glycoproteins.

Jan 24, 2024 · Despite variations in genome size and virus particle morphology, Nidovirales have been classified primarily based on their common genetic organization, a set of conserved domains and enzyme functions within the polyproteins, and their unique transcription strategy ( King et al., 2012 ).

Feb 28, 2006 · The comparison of the large corona-, toro- and roniviruses with their much smaller Arteriviridae cousins provides an intellectual framework for rationalizing the genome expansion in the Nidovirales. In this review, the common and unique features that have been recognized in either the large or even all nidoviruses were briefly discussed.

Jul 2, 2020 · Introduction. 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.
