studies of viruses in reptiles focused mainly on the zoonotic potential of arboviruses in reptiles and much effort went into surveys and challenge trials of a range of reptiles with eastern and western equine encephalitis as

classified into NCLDVs [9,10,11]. Because of these facts and of the impossibility of researching the viruses on the basis of their rRNA sequences, they cannot be regarded as falling within the currently used definition of three domains. In addition, based on the analysis of sequences of th...
The SARS-CoV-2 virus is a novel coronavirus of zoonotic origin. It is of spherical shape, but it can also exist as larger pleomorphic particles, measuring between 80 and 160 nm in length. The unique SARS-CoV-2 virus was named after the previously identified SARS-CoV and MERS-CoV viruses...
June 1997: There appears the first self encrypting virus for Windows95. This virus of Russian origin has been sent to several BBS is in Moscow which caused an epidemic. November 1997: The 'Esperanto' virus. This is the first virus that intends to infect not only DOS and Windows32 executabl...
This variant, named Gent1984/Diepholz-like swine H3N2, has a Gent/1984-like HA and a Diepholz/2008-like NA; the origin of the internal gene cassette likely derived from avian-like swine H1N1. The first isolate of the Gent1984/Diepholz reassortant emerged in Northern Germany in September 2011...
(1)nucleic acid type (2) nucleic acid strandedness (3) presence or absence of an envelope Recently, the International Committee for Taxonomy of Viruses has developed a uniform classification system and divided viruses into 56 families. The committee places greatest weight on three properties: ...
Host species/genus/species or genogroup/strain name/year of occurrence/country of origin. Adapted with permission from Green et al. J Infect Dis 2000; 181:5322-5330. The CV genomes are about 7.3–8.5 kilobases in length and organized in two or three open reading frames (ORFs). In the ...
(Idede2000). Therefore, NSDV may cause serious damage to the farming industry. NSDV was originally thought to be endemic only in East Africa, but a recent study showed that an Asian variant of NSDV called Ganjam virus (GV), can also be found in other places including India and Sri ...
Its origin is unclear, since it is neither evident in whole mounts nor in thin sections of free-living or intracellu- lar viruses. Its role is unclear too, since genomic mate- rial passing through the tail has never been seen. MpVN1 viruses or empty capsids were also observed attached ...
