Oxbow Virus
Oxbow virus (OXBV) is a single-stranded, enveloped, negative-sense RNA orthohantavirus.Kang HJ, Bennett SN, Dizney L, Sumibcay L, Arai S, Ruedas LA, Song JW, Yanagihara R.Host switch during evolution of a genetically distinct hantavirus in the American shrew mole (Neurotrichus gibbsii).Virology. 2009 May 25;388(1):8–14. Natural reservoir Oxbow virus was isolated from an American shrew mole (Neurotrichus gibbsii), captured in Gresham, Oregon, in September 2003. Virology The genome of the Oxbow virus along the full length of the S, M, and partial L-segment nucleotide and amino acid sequences show a low sequence similarity to rodent-borne hantaviruses. Phylogenetic analysis demonstrated that Oxbow virus and Asama virus are related to soricine shrew-borne hantaviruses found in North America, Europe, and Asia. This suggests both these viruses evolved with cross-species transmission. See also * Hantavirus pulmonary syndrome * Hantavirus hemorrhagic fever with renal syndrome * ...

Orthohantavirus
''Orthohantavirus'' is a genus of viruses that includes all hantaviruses (family ''Hantaviridae'') that cause disease in humans. Orthohantaviruses, hereafter referred to as hantaviruses, are naturally found primarily in rodents. In general, each hantavirus is carried by one rodent species and each rodent that carries a hantavirus carries one hantavirus species. Hantaviruses in their natural reservoirs usually cause an asymptomatic, persistent infection. In humans, however, hantaviruses cause two diseases: hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). HFRS is mainly caused by hantaviruses in Africa, Asia, and Europe, called Old World hantaviruses, and HPS is usually caused by hantaviruses in the Americas, called New World hantaviruses. Hantaviruses are transmitted mainly through aerosols and droplets that contain rodent excretions, as well as through contaminated food, bites, and scratches. Environmental factors such as rainfall, temperature, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Shrew Mole
The American shrew mole (''Neurotrichus gibbsii'') is the smallest species of mole. It is the only living member of the genus ''Neurotrichus'' and the tribe Neurotrichini. It is also known as Gibb's shrew mole and least shrew mole. It is not closely related to the Asian shrew mole (''Uropsilus'' in Urotrichini). Its shrew-like fur and typical mole head make the common name "shrew mole" fitting.Ronald M. Nowak"Walker's Mammals of the World, Volume 1"/ref> Habitat It is found in damp, forested or bushy areas with deep, loose soils in the northwestern United States and southwestern British Columbia. In the most northern part of its habitat, it lives along streams or moist dense woods and in the most southern part of its habitat, it is found in swampy areas that are overgrown with vegetation such as sedges or shrubs.Hartley Harrad Thompson Jackson"A review of the American moles"/ref> Morphological features Like shrews, it has a pelage with guard hairs and underfur.

Gresham, Oregon
Gresham ( ) is a city in the Willamette Valley, Located in Multnomah County in the U.S. state of Oregon, bordered by Portland to the northwest and partially in the southwest. It was first settled in the early 1850s by the Powell brothers. It remained unincorporated until 1905; it was named after Walter Quintin Gresham, an American Civil War general and United States Secretary of State. The early economy of the city was primarily supported by agriculture, and by the mid-20th century, the city saw a population boom, increasing from 4,000 residents to more than 10,000 between 1960 and 1970. The population was 114,247 at the 2020 census, making it the second most populous city in the county and the fourth-most populous city in Oregon. Gresham is an economic center for eastern Multnomah County. History The area now known as Gresham was first settled in 1851 by brothers Jackson and James Powell, who laid claim to land under the Donation Land Claim Act of 1850 and named the set ...

Hantavirus Pulmonary Syndrome
Hantavirus pulmonary syndrome (HPS), also called hantavirus cardiopulmonary syndrome (HCPS), is a severe respiratory disease caused by hantaviruses. The main features of illness are microvascular leakage and acute respiratory distress syndrome. Symptoms occur anywhere from one to eight weeks after exposure to the virus and come in three distinct phases. First, there is an early phase with flu-like symptoms such as fever, muscle aches, headache, and shortness of breath, as well as low platelet count. Second, there is cardiopulmonary phase during which people experience elevated or irregular heart rate, cardiogenic shock, and pulmonary capillary leakage, which can lead to respiratory failure, low blood pressure, and buildup of fluid in the lungs and chest cavity. The final phase is recovery, which typically takes months, but difficulties with breathing can persist for up to two years. The disease has a case fatality rate of 30 to 60 percent. Death usually occurs suddenly during the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hantavirus Hemorrhagic Fever With Renal Syndrome
Hantavirus hemorrhagic fever with renal syndrome (HFRS) is a hemorrhagic fever caused by hantaviruses. Symptoms usually occur 12–16 days after exposure to the virus and come in five distinct phases: febrile, hypotensive, low urine production (oliguric), high urine production (diuretic), and recovery. Early symptoms include headache, lower back pain, nausea, vomiting, diarrhea, bloody stool, the appearance of spots on the skin, bleeding in the respiratory tract, and renal symptoms such as kidney swelling, excess protein in urine, and blood in urine. During the hypotensive phase, blood pressure lowers due to microvascular leakage. Renal failure then causes the diuretic phase, before recovering and increasing urine production as disease progression improves. The severity of symptoms varies depending on which virus causes HFRS and ranges from a mild illness to severe. The case fatality rate likewise varies by virus, at less than 1% up to 15%. HFRS is caused mainly by four viruses in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross-species Transmission
Cross-species transmission (CST), also called interspecies transmission, host jump, or spillover, is the transmission of an infectious pathogen, such as a virus, between hosts belonging to different species. Once introduced into an individual of a new host species, the pathogen may cause disease for the new host and/or acquire the ability to infect other individuals of the same species, allowing it to spread through the new host population. The phenomenon is most commonly studied in virology, but cross-species transmission may also occur with bacterial pathogens or other types of microorganisms. Steps involved in the transfer of pathogens to new hosts include contact between the pathogen and the host; the successful infection of an initial individual host, which may lead to amplification and an outbreak; and the adaptation of the pathogen, within either the original or new host, which may render it capable of spreading efficiently between individuals in populations of the new h ...
