Nairovirus
''Orthonairovirus'' is a genus of viruses in the family ''Nairoviridae'' of the order ''Hareavirales'' which includes viruses with circular, RNA virus#Group V - negative-sense ssRNA viruses, negative-sense single stranded RNA. The name is derived from the Nairobi sheep disease which affects the gastrointestinal tracts of sheep and goats. All viruses in this genus are arbovirus, tick-borne viruses with human or other vertebrate hosts. Structure The Virus#Structure, virions for viruses in this genus have a spherical shape. They range in size from about 80–120 nm in diameter, with 50% of their weight attributed to proteins and 20–30% of their weight attributed to lipids. The ribonucleocapsid is filamentous, having a length of about 200-300 nm and a width of about 2–2.5 nm. These virus#Structure, nucleocapsids are surrounded by a single envelope that has projections made of glycoproteins protruding from its surface. These projections evenly cover the surf ...

Emerg Infect Dis. 2006 Jul;12(7):1074-1080 The word 'Kupe' is Kiswahili for tick. Genome The genome is composed a single strand of negative sense RNA in three parts - small (S), medium (M0 and large(L). The L segment RNA is 12,330 nucleotides (nt) in length and encodes one open reading frame In molecular biology, reading frames are defined as spans of DNA sequence between the start and stop codons. Usually, this is considered within a studied region of a prokaryotic DNA sequence, where only one of the six possib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arbovirus
Arbovirus is an informal name for any virus that is Transmission (medicine), transmitted by arthropod Vector (epidemiology), vectors. The term ''arbovirus'' is a portmanteau word (''ar''thropod-''bo''rne ''virus''). ''Tibovirus'' (''ti''ck-''bo''rne ''virus'') is sometimes used to more specifically describe viruses transmitted by ticks, a superorder within the arthropods. Arboviruses can affect both animals (including humans) and plants. In humans, symptoms of arbovirus infection generally occur 3–15 days after exposure to the virus and last three or four days. The most common clinical features of infection are fever, headache, and malaise, but encephalitis and viral hemorrhagic fever may also occur. Signs and symptoms The incubation period – the time between when infection occurs and when symptoms appear – varies from virus to virus, but is usually limited between 2 and 15 days for arboviruses. The majority of infections, however, are asymptomatic. Among cases in which sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avalon Virus
Avalon () is an island featured in the Arthurian legend. It first appeared in Geoffrey of Monmouth's 1136 ''Historia Regum Britanniae'' as a place of magic where King Arthur's sword Excalibur was made and later where Arthur was taken to recover from being gravely wounded at the Battle of Camlann. Since then, the island has become a symbol of Arthurian mythology, similar to Arthur's castle of Camelot. Avalon was associated from an early date with mystical practices and magical figures such as King Arthur's sorceress sister Morgan, cast as the island's ruler by Geoffrey and many later authors. Certain Briton traditions have maintained that Arthur is an eternal king who had never truly died but would return as the "once and future" king. The particular motif of his rest in Morgan's care in Avalon has become especially popular. It can be found in various versions in many French and other medieval Arthurian and other works written in the wake of Geoffrey, some of them also linking A ...

Vinegar Hill Virus
Vinegar () is an aqueous solution of diluted acetic acid and trace compounds that may include flavorings. Vinegar typically contains from 5% to 18% acetic acid by volume. Usually, the acetic acid is produced by a double fermentation, converting simple sugars to ethanol using yeast and ethanol to acetic acid using acetic acid bacteria. Many types of vinegar are made, depending on source materials. The product is now mainly used in the culinary arts as a flavorful, acidic cooking ingredient or in pickling. Various types are used as condiments or garnishes, including balsamic vinegar and malt vinegar. As the most easily manufactured mild acid, it has a wide variety of industrial and domestic uses, including functioning as a household cleaner. Etymology The word "vinegar" arrived in Middle English from Old French (''vyn egre''; sour wine), which in turn derives from Latin: (wine) + (neuter gender of , sour). Vinegar was formerly also called . The word "acetic" derives from La ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an arthropod exoskeleton, exoskeleton with a cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate, a body with differentiated (Metamerism (biology), metameric) Segmentation (biology), segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior Organ (anatomy), organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired Anatomical terms of location#Dorsal and ventral, ventral Ventral nerve cord, nerve cord ...

Host (biology)
In biology and medicine, a host is a larger organism that harbours a smaller organism; whether a parasite, parasitic, a mutualism (biology), mutualistic, or a commensalism, commensalist ''guest'' (symbiont). The guest is typically provided with nourishment and shelter. Examples include animals playing host to parasitic worms (e.g. nematodes), cell (biology), cells harbouring pathogenic (disease-causing) viruses, or a Fabaceae, bean plant hosting mutualistic (helpful) Rhizobia, nitrogen-fixing bacteria. More specifically in botany, a host plant supplies nutrient, food resources to micropredators, which have an evolutionarily stable strategy, evolutionarily stable relationship with their hosts similar to ectoparasitism. The host range is the collection of hosts that an organism can use as a partner. Symbiosis Symbiosis spans a wide variety of possible relationships between organisms, differing in their permanence and their effects on the two parties. If one of the partners in an ...
