Sin Nombre Orthohantavirus
''Sin Nombre orthohantavirus'' (SNV) (from Spanish, meaning "without a name") is the prototypical etiologic agent of hantavirus cardiopulmonary syndrome (HCPS). Discovered in 1993 near the Cañon de la Muerte on the Navajo Reservation, it was originally named the Muerto Canyon hantavirus, in keeping with the convention for naming new pathogens. However, the Navajo Nation objected to the name in 1994. It was also near the Four Corners point in the United States, so the virologists then tried naming it the "Four Corners virus". The name was changed after local residents raised objections. In frustration, the virologists changed it to ''Sin Nombre'', meaning "without a name" in Spanish. History It was first isolated in 1993 from rodents collected near the home of one of the initial patients with hantavirus pulmonary syndrome (HPS) in the Four Corners region of the western United States. Isolation was achieved through a blind passage in ''Peromyscus maniculatus'' (deer mouse) and su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmission Electron Microscopy
Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image is then magnified and focused onto an imaging device, such as a fluorescent screen, a layer of photographic film, or a sensor such as a scintillator attached to a charge-coupled device. Transmission electron microscopes are capable of imaging at a significantly higher resolution than light microscopes, owing to the smaller de Broglie wavelength of electrons. This enables the instrument to capture fine detail—even as small as a single column of atoms, which is thousands of times smaller than a resolvable object seen in a light microscope. Transmission electron microscopy is a major analytical method i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vero E6 Cells
Vero cells are a lineage of cells used in cell cultures. The 'Vero' lineage was isolated from kidney epithelial cells extracted from an African green monkey ('' Chlorocebus'' sp.; formerly called ''Cercopithecus aethiops'', this group of monkeys has been split into several different species). The lineage was developed on 27 March 1962, by Yasumura and Kawakita at the Chiba University in Chiba, Japan. The original cell line was named '' Vero'' after an abbreviation of , which means 'green kidney' in Esperanto, while itself means 'truth' in Esperanto. Characteristics The Vero cell lineage is continuous and aneuploid, meaning that it has an abnormal number of chromosomes. A continuous cell lineage can be replicated through many cycles of division and not become senescent. Vero cells are interferon-deficient; unlike normal mammalian cells, they do not secrete interferon alpha or beta when infected by viruses. However, they still have the Interferon-alpha/beta receptor, so th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hantavirus
''Orthohantavirus'' is a genus of single-stranded, enveloped, negative-sense RNA viruses in the family ''Hantaviridae'' within the order ''Bunyavirales''. Members of this genus may be called orthohantaviruses or simply hantaviruses. Orthohantaviruses typically cause chronic asymptomatic infection in rodents. Humans may become infected with hantaviruses through contact with rodent urine, saliva, or feces. Some strains cause potentially fatal diseases in humans, such as hantavirus hemorrhagic fever with renal syndrome (HFRS), or hantavirus pulmonary syndrome (HPS), also known as hantavirus cardiopulmonary syndrome (HCPS), while others have not been associated with known human disease (e.g. Prospect Hill virus). HPS (HCPS) is a "rare respiratory illness associated with the inhalation of aerosolized rodent excreta (urine and feces) contaminated by hantavirus particles." Human infections of hantaviruses have almost entirely been linked to human contact with rodent excrement; however, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1993 Four Corners Hantavirus Outbreak
The 1993 Four Corners hantavirus outbreak was an outbreak of hantavirus that caused the first known human cases of hantavirus disease in the United States. It occurred within the Four Corners region – the geographic intersection of the U.S. states of Utah, Colorado, New Mexico, and Arizona – of the Southwestern United States in mid-1993. This region is largely occupied by Native American tribal lands, including the Hopi, Ute, Zuni, and Navajo reservations, from which many of the cases were reported. The virus killed 13 people — half of those it infected, for a mortality rate of 50%. The cause of the outbreak was found to be a previously unknown species of hantavirus, which was responsible for a new form of illness known as hantavirus pulmonary syndrome or HPS. The virus is carried by deer mice. Originally referred to as "Four Corners virus", "Muerto Canyon virus", and "Convict Creek virus", it was later named Sin Nombre virus. Transmission to humans was found to have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microtus
''Microtus'' is a genus of voles found in North America, Europe and northern Asia. The genus name refers to the small ears of these animals. About 62 species are placed in the genus. They are stout rodents with short ears, legs and tails. They eat green vegetation such as grasses and sedges in summer, and grains, seeds, root and bark at other times. The genus is also called "meadow voles".

Microtus Californicus
The California vole (''Microtus californicus'') is a type of vole which lives throughout much of California and part of southwestern Oregon. It is also known as the "California meadow mouse", a misnomer as this species is a vole, not a mouse. It averages in length although this length varies greatly between subspecies. Description The California vole is a medium-sized vole, and a typical member of its group in appearance. Males range from in head-body length, with a tail. Females are significantly smaller at in length with a tail. Males weigh from , and females from . Variation between different subspecies, though, is considerable, with the southern subspecies tending to be larger than those found further north. The body is covered with cinnamon to tawny olive fur, ticked with occasional darker hairs, and fading to a medium grey on the underside. The tail is black above and grey below. The whiskers and feet are grey in color, with a patch of white fur near the anus. Between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microtus Arvalis
The common vole (''Microtus arvalis'') is a European rodent. Distribution and habitat The common vole is hardly restricted in means of distribution and habitat and inhabits large areas of Eurasia but, apart from the Orkney vole, not the British Isles. As ''Microtus arvalis'' followed human civilization, primary and secondary habitats can be distinguished. The primary habitats are everything but dense forests, such as meadows, heath lands, and fallow land. The secondary habitats are mainly agricultural fields, where shallow sloped areas are preferred. The natural food of the common vole is grass, but it also feeds on many agricultural crops (within secondary habitats) and here its reproduction is faster than in primary habitats. Reproduction, demography, and predation After pregnancy of 16 to 24 days, females give birth to 3 to 8 juveniles, weighing between 1.0 and 3.1 g. Weaning is around the 20th day. Female juveniles can be impregnated from the 13th day after birth. Hen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
