Aparavirus
''Aparavirus'' is a genus of viruses in the order '' Picornavirales'', in the family '' Dicistroviridae''. Invertebrates, honeybee, and bumblebees serve as natural hosts. There are six species in this genus. Diseases associated with this genus include: ABPV: paralysis. This virus plays a role in sudden collapse of honey bee colonies infested with the parasitic mite varroa destructor. Taxonomy The genus contains the following species: *'' Acute bee paralysis virus'' *'' Israeli acute paralysis virus'' *'' Kashmir bee virus'' *''Mud crab virus'' *''Solenopsis invicta virus-1'' *''Taura syndrome virus Taura is a municipality in the district of Mittelsachsen, in Saxony, Germany.

Dicistroviridae
''Dicistroviridae'' is a family of viruses in the order ''Picornavirales''. Invertebrates, including aphids, leafhoppers, flies, bees, ants, and silkworms, serve as natural hosts. There are 15 species in this family, assigned to three genera. Diseases associated with this family include: DCV: increased reproductive potential. extremely pathogenic when injected with high associated mortality. CrPV: paralysis and death. Taxonomy Although many dicistroviruses were initially placed in the ''Picornaviridae'', they have since been reclassified into their own family. The name (Dicistro) is derived from the characteristic dicistronic arrangement of the genome. This family is a member of the Order ''Picornavirales'' (along with the families '' Iflaviridae'', ''Picornaviridae'', and ''Secoviridae'' and ''Marnaviridae''). Within this order, the gene order is the gene order of the nonstructural proteins Hel(helicase)-Pro(protease)-RdRp(polymerase). The ''Dicistroviridae'' can be distingui ...

Viruses
A virus is a submicroscopic infectious agent that replicates only inside the living cells Cell most often refers to: * Cell (biology), the functional basic unit of life Cell may also refer to: Locations * Monastic cell, a small room, hut, or cave in which a religious recluse lives, alternatively the small precursor of a monastery w ... of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. 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,Dimmock p. 4 more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is ofte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Picornavirales
''Picornavirales'' is an order of viruses with vertebrate, invertebrate, protist and plant hosts. The name has a dual etymology. First, ''picorna-'' is an acronym for poliovirus, insensitivity to ether, coxsackievirus, orphan virus, rhinovirus, and ribonucleic acid. Secondly, pico-, meaning extremely small, combines with RNA to describe these very small RNA viruses. The order comprises viruses that historically are referred to as picorna-like viruses. Characteristics The families within this order share a number of common features: * The virions are non- enveloped, icosahedral, and about 30 nanometers in diameter. * The capsid has a "pseudo T=3" structure, and is composed of 60 protomers each made of three similar-sized but nonidentical beta barrels. * The genome is made of one or a few single-stranded RNA(s) serving directly as mRNA, without overlapping open reading frames. * The genome has a small protein, VPg, covalently attached to its 5' end, and usually a pol ...

Acute Bee Paralysis Virus
Diseases of the honey bee or abnormal hive conditions include: Pests and parasites ''Varroa'' mites '' Varroa destructor'' and ''V. jacobsoni'' are parasitic mites that feed on the fat bodies of adult, pupal and larval bees. When the hive is very heavily infested, '' Varroa'' mites can be seen with the naked eye as a small red or brown spot on the bee's thorax. ''Varroa'' mites are carriers for many viruses that are damaging to bees. For example, bees infected during their development will often have visibly deformed wings. ''Varroa'' mites have led to the virtual elimination of feral bee colonies in many areas, and are a major problem for kept bees in apiaries. Some feral populations are now recovering—it appears they have been naturally selected for ''Varroa'' resistance. ''Varroa'' mites were first discovered in Southeast Asia in about 1904, but are now present on all continents except Australia. They were discovered in the United States in 1987, in New Z ...

Mud Crab Virus
A MUD (; originally multi-user dungeon, with later variants multi-user dimension and multi-user domain) is a multiplayer real-time virtual world, usually text-based or storyboarded. MUDs combine elements of role-playing games, hack and slash, player versus player, interactive fiction, and online chat. Players can read or view descriptions of rooms, objects, other players, non-player characters, and actions performed in the virtual world. Players typically interact with each other and the world by typing commands that resemble a natural language. Traditional MUDs implement a role-playing video game set in a fantasy world populated by fictional races and monsters, with players choosing classes in order to gain specific skills or powers. The objective of this sort of game is to slay monsters, explore a fantasy world, complete quests, go on adventures, create a story by roleplaying, and advance the created character. Many MUDs were fashioned around the dice-rolling rul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
