Parramatta River Virus
Parramatta River virus (PaRV) is an insect virus belonging to ''Flaviviridae'' and endemic to Australia. It was discovered in 2015. The virus was identified from the mosquito ''Aedes vigilax'' collected from Sydney under the joint research project by scientists at the University of Queensland and the University of Sydney. In experimental infections, the virus is unable to grow in vertebrate cells, but only in ''Aedes''-derived mosquito cell lines. This suggests that the virus does not infect vertebrates. The name is given because it was discovered from Silverwater, a suburb of Sydney on the southern bank of the Parramatta River. The mosquitoes from which the virus was isolated were actually collected in 2007, and had been preserved since then. The study commenced only after the development of the technique of viral detection in mosquitoes in the University of Queensland. The virus was identified as a result of investigation on the outbreak of '' Ross River virus'' in 2015. Both the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flaviviridae
''Flaviviridae'' is a family of enveloped positive-strand RNA viruses which mainly infect mammals and birds. They are primarily spread through arthropod vectors (mainly ticks and mosquitoes). The family gets its name from the yellow fever virus; ''flavus'' is Latin for "yellow", and yellow fever in turn was named because of its propensity to cause jaundice in victims. There are 89 species in the family divided among four genera. Diseases associated with the group include: hepatitis (hepaciviruses), hemorrhagic syndromes, fatal mucosal disease (pestiviruses), hemorrhagic fever, encephalitis, and the birth defect microcephaly (flaviviruses). Structure Virus particles are enveloped and spherical with icosahedral-like geometries that have pseudo T=3 symmetry. They are about 40–60 nm in diameter. Genome Members of the family ''Flaviviridae'' have monopartite, linear, single-stranded RNA genomes of positive polarity, and 9.6 to 12.3 kilobase in total length. The 5'-termini of ...

Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Silverwater, New South Wales
Silverwater is a suburb in western Sydney, in the state of New South Wales, Australia. Silverwater is located 15 kilometres west of the Sydney central business district on the southern bank of the Parramatta River within the local government area of City of Parramatta. History The origin of the suburb's name is unknown. It may have been a reference to the nearby Parramatta River which could have provided ''silver'' reflections of light off the ''water''. The name was used when this part of the larger Newington Estate was first subdivided, in 1883. Industrial and residential developments occurred in parallel. In 1906, the area was first incorporated into the Borough of Auburn, later City of Auburn, until it was abolished in 2016. Significant parts of the suburb became industrial land during the 20th century, due to the easy access to and from the suburb by road (east-west on Parramatta Road and north–south on the A6 arterial road) and by water on Parramatta River. Some of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parramatta River
The Parramatta River is an intermediate tide-dominated, drowned valley estuary located in Sydney, New South Wales, Australia. With an average depth of , the Parramatta River is the main tributary of Sydney Harbour, a branch of Port Jackson. Secondary tributaries include the smaller Lane Cove and Duck rivers. Formed by the confluence of Toongabbie Creek and Darling Mills Creek at North Parramatta, the river flows in an easterly direction to a line between Yurulbin in Birchgrove and Manns Point in Greenwich. Here it flows into Port Jackson, about from the Tasman Sea. The total catchment area of the river is approximately and is tidal to Charles Street Weir in Parramatta, approximately from the Sydney Heads. The land adjacent to the Parramatta River was occupied for many thousands of years by Aboriginal peoples of the Wallumettagal nations and the Wangal, Toongagal (or Tugagal), Burramattagal, and Wategora clans of the Darug people. They used the river as an important source o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ross River Virus
''Ross River virus'' (RRV) is a small encapsulated single-strand RNA ''Alphavirus'' endemic to Australia, Papua New Guinea and other islands in the South Pacific. It is responsible for a type of mosquito-borne non-lethal but extremely debilitating tropical disease known as Ross River fever, previously termed "epidemic polyarthritis". There is no known cure, and it can last in the system of the host for up to 20 years. The virus is suspected to be enzootic in populations of various native Australian mammals, and has been found on occasion in horses. Classification and morphology Taxonomically, ''Ross River virus'' belongs to the virus genus ''Alphavirus'', which is part of the family ''Togaviridae''. The alphaviruses are a group of small enveloped single-strand positive-sense RNA viruses. RRV belongs to a subgroup of "Old World" (Eurasian-African-Australasian) alphaviruses, and is considered closely related to Sagiyama virus. The virions (virus particles) themselves contain t ...

Sanger Sequencing
Sanger sequencing is a method of DNA sequencing that involves electrophoresis and is based on the random incorporation of chain-terminating dideoxynucleotides by DNA polymerase during in vitro DNA replication. After first being developed by Frederick Sanger and colleagues in 1977, it became the most widely used sequencing method for approximately 40 years. It was first commercialized by Applied Biosystems in 1986. More recently, higher volume Sanger sequencing has been replaced by next generation sequencing methods, especially for large-scale, automated genome analyses. However, the Sanger method remains in wide use for smaller-scale projects and for validation of deep sequencing results. It still has the advantage over short-read sequencing technologies (like Illumina) in that it can produce DNA sequence reads of > 500 nucleotides and maintains a very low error rate with accuracies around 99.99%. Sanger sequencing is still actively being used in efforts for public health initiative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ochlerotatus
''Ochlerotatus'' is a genus of mosquito. Until 2000, it was ranked as a subgenus of ''Aedes'', but after Reinert's work, the clade was upgraded to the level of a genus. This change has resulted in the renaming of many subgenus species, and many aedini-related taxa are undergoing taxonomic revisions. Some authors are still using traditional taxonomic names in their publications. Taxonomy ''Ochlerotatus'' was originally established as a genus in 1891.Félix Lynch Arribálzaga. 1891. Dipterologia Argentina, Culicidae. '' Revista del Museo de la Plata'', i: 345–377; p. 374. In 1917, a researcher by the name of Edwards transferred it to the aedine subgenus; however, as of 2000, ''Ochlerotatus'' has resumed its role as a genus (a revision made by Reinhert, due to common traits in genitalia). Based on taxonomic characteristics, many species and subgenera of ''Aedes'' mosquitoes have been transferred to the ''Ochlerotatus'' genus. After a contentious worldwide debate regarding the e ...
