Phleboviruses
''Phlebovirus'' is a genus of viruses in the family ''Phenuiviridae'' in the order '' Hareavirales''. The genus contains 67 species. It derives its name from Phlebotominae, the vectors of member species Sandfly fever Naples virus, which is said to be ultimately from the Greek , meaning "vein". The proper word for "vein" in ancient Greek is however ''phleps'' (φλέψ). Virology Phleboviruses are viruses with a negative-sense RNA genome consisting of three segments. The small segment (S) codes for the viral N protein and a non structural protein, NSs via an ambisense coding strategy. The medium-sized segment (M) codes for a precursor of the viral glycoproteins and non-structural components. The product of the largest segment (L) is the viral RNA-dependent RNA polymerase. Replication Phleboviruses replicate in a seven step process. First, the cellular attachment is driven through the glycoprotein interactions with host cells. Examples of this are Dendritic Cell-Specific In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandfly Fever Naples Virus
Sandfly fever Naples virus is an antigenic species of genus ''Phlebovirus'' within the family ''Phenuiviridae'' of the order '' Hareavirales''. It is an enveloped RNA virus with a tripartite genome. Its natural reservoir are sandflies. The SFNV serogroup consists of two main serocomplexes associated with disease in humans, the Naples and Sicilian serocomplexes. Sandfly fever induces myalgia, fever, and elevated liver enzymes in humans. It is difficult to diagnose outside endemic areas. Natural reservoir Phlebotomine sandflies (Psychodidae Psychodidae, also called drain flies, sink flies, filter flies, sewer flies, or sewer gnats, is a Family (biology), family of Fly, true flies. Some genera have short, hairy bodies and wings, giving them a "furry" moth-like appearance, hence one ...) are the natural reservoir and transmit to humans via bite. Psychodidae has a wide geographical distribution. References External links Sandfly fever Naples virus taxonomy* Database search r ...

Toscana Virus
Toscana virus (TOSV) is an arbovirus (arthropod-borne virus) belonging to '' Bunyaviricetes'', a class of negative-stranded, enveloped RNA viruses. The virus can be transmitted to humans by the bite of an infected sandfly of the genus '' Phlebotomus''. Toscana is not normally associated with disease, as indicated by high seroprevalence rates (up to 25%) in endemic areas, but in common with other sandfly transmitted viruses such as '' Naples virus'' and '' Sicilian virus'', infection may result in Pappataci fever, an illness with mild fever, headache and myalgia. In serious cases that go undiagnosed, acute meningitis, meningoencephalitis and encephalitis may occur. There is no specific treatment for infection, so treatment is supportive, reducing the severity of symptoms until the immune system has cleared the infection. The virus is found in most countries that border the Mediterranean Sea, with the highest incidence in Italy. Infection rates peak during the summer time as sand ...

Punta Toro Virus
Punta Toro virus is a member of the genus ''Phlebovirus'' of the family ''Phenuiviridae''. It was initially isolated from patients in Colombia and two key patients in Panama Panama, officially the Republic of Panama, is a country in Latin America at the southern end of Central America, bordering South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and .... Two individual serotypes of PTV were isolated from these patients, PTV-Adames (A) and PTV-Balliet (B), with PTV-A appearing to be more virulent. PTV is considered to be relatively contained to the Americas with no cases being reported outside of this region. Along with a few other human pathogenic phleboviruses, PTV is considered to be a significant virus in terms of public health as little information is known about its clinical effects and with further research underway, PTV could have unforeseen impacts on health and virology. Structure PTV possesses m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alenquer Virus
Alenquer virus (ALEV) is a virus in the genus ''Phlebovirus''. Alenquer virus was one of eight arthropod-borne viruses first isolated in the early 1980s from sites along roads built into the Amazon rainforest in Brazil for settlers. Sporadic cases of febrile illness have occurred in humans who live in jungle areas in Brazil and Panama Panama, officially the Republic of Panama, is a country in Latin America at the southern end of Central America, bordering South America.

Taxonomy
image:Hierarchical clustering diagram.png, 280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the Taxonomy (biology), classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchy, hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a Taxonomy for search e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Adana Virus
Adana is a large city in southern Turkey. The city is situated on the Seyhan River, inland from the northeastern shores of the Mediterranean Sea. It is the administrative seat of the Adana province, and has a population of 1 816 750 (Seyhan, Yuregir, Cukurova, Saricam), making it the largest city in the Mediterranean Region of Turkey. Adana lies in the heart of Cilicia, which some say, was once one of the most important regions of the classical world. Home to six million people, Cilicia is an important agricultural area, owing to the large fertile plain of Çukurova. Adana is a centre for regional trade, healthcare, and public and private services. Agriculture and logistics are important parts of the economy. The city is connected to Tarsus and Mersin by TCDD train. The closest public airport is Çukurova International Airport. Etymology The name Adana (; ; ) has been used for over four millennia. One theory holds that the city name originates from an Indo-European express ...

Viral Hemorrhagic Fever
Viral hemorrhagic fevers (VHFs) are a diverse group of diseases. "Viral" means a health problem caused by infection from a virus, " hemorrhagic" means to bleed, and "fever" means an unusually high body temperature. Bleeding and fever are common signs of VHFs, which is how the group of infections got its common name. There are five known families of RNA viruses which cause VHFs: '' Arenaviridae'', '' Filoviridae'', '' Flaviviridae'', '' Hantaviridae'', and ''Rhabdoviridae''. Some VHFs are usually mild, such as nephropathia epidemica (within the family ''Hantaviridae''). But some are usually severe and have a high death rate, such as Ebola virus (within the family ''Filoviridae''). All VHFs can potentially cause severe blood loss, high fever, and death. Both humans and non human animals can be infected. Signs and symptoms The following are signs and symptoms of most or all VHFs. * Circulatory shock *Diarrhea (feces which resemble more liquid than solid) *Headache *Hypotens ...

Viral Encephalitis
Viral encephalitis is inflammation of the brain parenchyma, called encephalitis, by a virus. The different forms of viral encephalitis are called viral encephalitides. It is the most common type of encephalitis and often occurs with viral meningitis. Encephalitic viruses first cause infection and replicate outside of the central nervous system (CNS), most reaching the CNS through the circulatory system and a minority from nerve endings toward the CNS. Once in the brain, the virus and the host's inflammatory response disrupt neural function, leading to illness and complications, many of which frequently are neurological in nature, such as impaired motor skills and altered behavior. Viral encephalitis can be diagnosed based on the individual's symptoms, personal history, such as travel history, and different clinical tests such as histology, medical imaging, and lumbar punctures. A differential diagnosis can also be done to rule out other causes of the encephalitis. Many encephalitic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pappataci Fever
Pappataci fever (also known as phlebotomus fever and, somewhat confusingly, sandfly fever and three-day fever) is a vector-borne febrile arboviral infection caused by three serotypes of Phlebovirus. It occurs in subtropical regions of the Eastern Hemisphere. The name, pappataci fever, comes from the Italian word for sandfly; it is the union of the words ''pappa'' (usually this is used as a generic name for food, but in this case it is a ''verb'' meaning "eating") and ''taci'' (silent), distinguishing these insects from blood-feeding mosquitoes, which produce a typical noise while flying. Signs and symptoms A few days after the infective bite, a feeling of lassitude, abdominal distress and chills develop followed by fever of , severe frontal headaches, muscle and joint aches, flushing of the face and a fast heart rate. After two days the fever begins to subside and the temperature returns to normal. Fatigue, a slow heart rate and low blood pressure may persist from a few days ...
