Starlingpox
Starlingpox virus is a virus of the ''Avipoxvirus'' genus belonging to the ''Chordopoxvirinae'' subfamily and the ''Poxviridae'' family, impacting various starling songbird species (Weli and Tryland 2011). The starling variant, Starlingpox virus has been linked to another variant, the Mynahpox virus, supporting theorizations that each variation belongs to a subclade, Sturnindaepox virus (Gyuranecz, et al. 2013). Avian pox viruses are widespread, double-stranded, DNA genome viruses that have been found in cutaneous and diphtheritic forms in over 230 bird species. Signs and symptoms The virus presents with "dry", cutaneous, "wart-like" lesions that may cause vision impairments and trouble eating, or "wet", diphtheritic lesions that may disrupt respiration or lead to secondary bacterial or fungal infections (Lawson, et al., 2012). The most well-known symptoms are lesions on the head, concentrated around the eyes and base of the beak (Bateson and Asher, 2010). Infected birds often ha ...

Avipoxvirus
''Avipoxvirus'' (avian pox) is a genus of viruses within the family ''Poxviridae''. ''Poxviridae'' is the family of viruses which cause the afflicted organism to have poxes as a symptom. Poxviruses have generally large genomes, and other such examples include smallpox and monkeypox. Members of the genus ''Avipoxvirus'' infect specifically birds. Avipoxviruses are unable to complete their replication cycle in non-avian species. Although it is comparably slow-spreading, ''Avipoxvirus'' is known to cause symptoms like Cutaneous condition#Nodule, pustules lining the skin and diphtheria-like symptoms. These diphtheria-like symptoms might include diphtheric necrosis, necrotic membranes lining the mouth and the Respiratory tract#Upper respiratory tract, upper respiratory tract. Like other avian viruses, it can be transmitted through vectors mechanically such as through mosquitoes. There is no evidence that this virus can infect humans. ''Avipoxvirus'' is a virus that is brick-shaped and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virus
A virus is a submicroscopic infectious agent that replicates only inside the living Cell (biology), cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, more than 16,000 of the millions of List of virus species, virus species have been described in detail. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent viral particles, or ''virions'', consisting of (i) genetic material, i.e., long ...
