Canarypox
Canarypox virus (CNPV) is an ''Avipoxvirus'' and etiologic agent of canarypox, a disease of wild and captive birds that can cause significant losses. Canarypox can enter human cells, but it cannot survive and multiply in human cells. There is a live viral vaccine available which may have beneficial properties against human cancer when used as a mammalian expression vector. (ATCvet code: ). Furthermore, the POXIMUNE® C vaccine does offer direct protection against CNPV in susceptible birds. Generally CNPV is considered a disease of songbirds, such as canaries, magpies and nightingales, and is associated with higher mortality rates when compared to other avian pox viruses. In some instances, mortality approaches 100%. Avian pox viruses also cause significant economic losses in domestic poultry and remain a problem in the conservation of endemic bird species inhabiting islands. The general symptoms of CNPV are similar to those of other species of avian pox viruses and are charac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turkeypox
''Turkeypox virus'' is a virus of the family ''Poxviridae'' and the genus ''Avipoxvirus'' that causes turkeypox. It is one of the most common diseases in the wild turkey (''Meleagris gallopavo'') population. Turkeypox, like all avipoxviruses, is transmitted either through skin contact or by arthropods (typically mosquitos) acting as mechanical vectors. ''Turkeypox virus'' was first reported in a turkey flock in New York by E.L. Burnett, and may be identified by nodular proliferative skin lesions on the non-feathered parts of the body and in the fibrino-necrotic and proliferative lesions in the mucous membrane of the upper respiratory tract. Viral classification Turkeypox virus is a member of the family ''Poxviridae'' and is in the genus ''Avipoxvirus''. There are currently 9 other species within this genus: ''Fowlpox'' virus, ''Juncopox'' virus, ''Mynahpox'' virus, ''Psittacinepox'' virus, ''Sparrowpox'' virus, ''Starlingpox'' virus, ''Pigeonpox'' virus, ''Canarypox'' virus an ...

Canary (Serinus Canaria)
Canary originally referred to the island of Gran Canaria on the west coast of Africa, and the group of surrounding islands (the Canary Islands). It may also refer to: Animals Birds * Canaries, birds in the genera ''Serinus'' and ''Crithagra'' including, among others: ** Atlantic canary (''Serinus canaria''), a small wild bird *** Domestic canary, ''Serinus canaria domestica'', a small pet or aviary bird, also responsible for the "canary yellow" color term ** Yellow canary (''Serinus flaviventris''), a small bird Fish * Canary damsel (''Similiparma lurida''), fish of the family Pomacentridae, found in the eastern Atlantic Ocean * Canary moray (''Gymnothorax bacalladoi''), an eel of the family Muraenidae * Canary rockfish (''Sebastes pinniger''), of the family Sebastidae, found in the northeast Pacific Ocean People * Canary Burton (born 1942), American keyboardist, composer and writer * Canary Conn (born 1949), American entertainer and author * Bill Canary (fl. 1994), Republican c ...

Gene Expression
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce end products, protein or non-coding RNA, and ultimately affect a phenotype, as the final effect. These products are often proteins, but in non-protein-coding genes such as transfer RNA (tRNA) and small nuclear RNA (snRNA), the product is a functional non-coding RNA. Gene expression is summarized in the central dogma of molecular biology first formulated by Francis Crick in 1958, further developed in his 1970 article, and expanded by the subsequent discoveries of reverse transcription and RNA replication. The process of gene expression is used by all known life—eukaryotes (including multicellular organisms), prokaryotes (bacteria and archaea), and utilized by viruses—to generate the macromolecular machinery for life. In genetics, gene expression is the most fundamental level at which the genotype gives rise to the phenotype, '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virosome
A virosome is a drug or vaccine delivery mechanism consisting of unilamellar phospholipid membrane (either a mono- or bi-layer) vesicle incorporating virus derived proteins to allow the virosomes to fuse with target cells. Viruses are infectious agents that can replicate in their host organism, however virosomes do not replicate. The properties that virosomes share with viruses are based on their structure; virosomes are essentially safely modified viral envelopes that contain the phospholipid membrane and surface glycoproteins. As a drug or vaccine delivery mechanism they are biologically compatible with many host organisms and are also biodegradable. The use of reconstituted virally derived proteins in the formation of the virosome allows for the utilization of what would otherwise be the immunogenic properties of a live-attenuated virus, but is instead a safely killed virus. A safely killed virus can serve as a promising vector because it won't cause infection and the viral str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
