Positive-sense Single-stranded RNA Virus
Positive-strand RNA viruses (+ssRNA viruses) are a group of related viruses that have positive-sense, single-stranded genomes made of ribonucleic acid. The positive-sense genome can act as messenger RNA (mRNA) and can be directly translated into viral proteins by the host cell's ribosomes. Positive-strand RNA viruses encode an RNA-dependent RNA polymerase (RdRp) which is used during replication of the genome to synthesize a negative-sense antigenome that is then used as a template to create a new positive-sense viral genome. Positive-strand RNA viruses are divided between the phyla ''Kitrinoviricota'', ''Lenarviricota'', and ''Pisuviricota'' (specifically classes ''Pisoniviricetes'' and '' Stelpavirictes'') all of which are in the kingdom '' Orthornavirae'' and realm '' Riboviria''. They are monophyletic and descended from a common RNA virus ancestor. In the Baltimore classification system, +ssRNA viruses belong to Group IV. Positive-sense RNA viruses include pathogens s ...

Deltacoronavirus (genus)
''Deltacoronavirus'' (Delta-CoV) is one of the four Genus, genera (''Alphacoronavirus, Alpha-'', ''Betacoronavirus, Beta-'', ''Gammacoronavirus, Gamma-'', and ''Delta-'') of coronaviruses. It is in the subfamily ''Orthocoronavirinae'' of the family ''Coronaviridae''. They are Viral envelope, enveloped, Sense (molecular biology), positive-sense, Base pair, single-stranded RNA viruses. Deltacoronaviruses infect mostly birds and some mammals. While the alpha and beta genera are derived from the Bat virome, bat viral gene pool, the gamma and delta genera are derived from the avian and pig viral gene pools. Genetic recombination, Recombination appears to be common among deltacoronaviruses.Lau SKP, Wong EYM, Tsang CC, Ahmed SS, Au-Yeung RKH, Yuen KY, Wernery U, Woo PCY.

Light-vented Bulbul
The light-vented bulbul (''Pycnonotus sinensis''), also called the Chinese bulbul, is a species of bird in the bulbul family found in central and southern China, Hong Kong, Macao, northern Vietnam, southern Japan and Taiwan, with occasional records from South Korea. A common species of songbird that favors lightly wooded habitats, it can frequently be seen in towns, suburbs and urban parks within its range. Taxonomy and systematics The light-vented bulbul was originally described in the genus ''Muscicapa''. Subspecies Four subspecies are recognized: * ''P. s. sinensis'' ( Gmelin, JF, 1789) – Found in central and eastern China. * ''P. s. hainanus'' ( Swinhoe, 1870) – Originally described as a separate species in the genus ''Ixos''. Found in south-eastern China and northern Vietnam. * ''P. s. formosae'' Hartert, E, 1910 – Found on Taiwan. * ''P. s. orii'' Kuroda, 1923 – Found on Yonaguni, Okinawa, Iriomote and Ishigaki Islands (southern Ryukyu Islands).

Bird Diseases
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
