Arnidovirineae

	Arnidovirineae ''Arnidovirineae'' is a suborder of viruses in the order Nidovirales. There are 4 families and 16 genera in the Arnidovirineae suborder. 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.

picture info	Arteriviridae ''Arteriviridae'' is a family of enveloped, positive-strand RNA viruses in the order ''Nidovirales'' which infect vertebrates. Host organisms include equids, pigs, Possums, nonhuman primates, and rodents. The family includes, for example, equine arteritis virus in horses which causes mild-to-severe respiratory disease and reproductive failure, porcine reproductive and respiratory syndrome virus type 1 and type 2 in pigs which causes a similar disease, simian hemorrhagic fever virus which causes a highly lethal fever, lactate dehydrogenase–elevating virus which affects mice, and wobbly possum disease virus. Structure Member viruses are enveloped, spherical, and 45–60 nm in diameter. Genome Arteriviruses have a positive-sense In molecular biology and genetics, the sense of a nucleic acid molecule, particularly of a strand of DNA or RNA, refers to the nature of the roles of the strand and its complement in specifying a sequence of amino acids.

picture info	Nidovirales ''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,'' and ''Mesoniviridae''. Member viruses have a viral envelope and a positive-sense, single-stranded RNA genome which is capped and polyadenylated. Nidoviruses are named for the Latin ''nidus'', meaning nest, as all viruses in this order produce a 3' co-terminal nested set of subgenomic mRNAs during infection. Virology Structure Nidoviruses have a viral envelope and a positive-sense, single-stranded RNA genome which is capped and polyadenylated. The group expresses structural proteins separately from the nonstructural ones. The structural proteins are encoded at the 3’ region of the genome and are expressed from a set of subgenomic mRNAs. Member viruses encode one main protei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Gammaarterivirus Lactate dehydrogenase elevating virus (LDV) constitutes the species ''Gamamaarterivirus lacdeh'' which is part of the family '' Arteriviridae'' and order ''Nidovirales''. The order ''Nidovirales'' also includes the family of coronaviruses. Arteriviruses infect macrophages in animals and cause a variety of diseases. LDV specifically causes lifelong persistent viremia in mice, but does not harm the host and only slightly harms the immune system. The main clinical sign is an increased level of the plasma enzyme lactate dehydrogenase (LDH). LDV has a remarkably narrow cell type specificity, meaning nothing homologous with LDV in mice has been found in another species. Discovery LDV was discovered in 1960 by Dr. Vernon Riley and his colleagues while they were working with plasma enzymes in tumor-bearing mice. They found that many types of transplantable tumors caused a five to tenfold increase in the plasma lactate dehydrogenase (LDH) activity within three days of the transplantatio ...

	Betaarterivirus ''Betaarterivirus'' is a genus of enveloped, positive-strand RNA viruses which infect vertebrates. The genus is in the family '' Arteriviridae'' and order ''Nidovirales''. The genus contains four subgenera and six species. Structure Member viruses are enveloped, spherical, and 45–60 nm in diameter. Genome Betaarteriviruses have a positive-sense single-stranded RNA genome.

	Deltaarterivirus Hemfev ''Deltaarterivirus hemfev'', formerly ''Simian hemorrhagic fever virus'' or ''simian haemorrhagic fever virus'' (SHFV), is a highly pathogenic virus in monkeys. It is a positive-stranded RNA virus classified in the family '' Arteriviridae''. It is the only member of the subgenus ''Hedartevirus''. Hosts Patas are believed to be the natural host for the virus since about 50% of wild patas monkeys have antibodies for the virus, while antibodies are much less prevalent in other simian species such as vervets and baboons. In macaques, however, infection with this virus can result in acute severe disease with high mortality. Recently, red colobus monkeys and red-tailed guenons have been identified as natural hosts for SHFV. In 2022, scientists cautioned about potential future spillover of SHFV. Symptoms Asymptomatic infection of the virus can occur in patas monkeys, vervet monkeys, and baboons, although it is observed primarily in patas monkeys. Infection has a rapid onset ...
