Bayou Virus
''Bayou orthohantavirus'' (BAYV) is a species of ''Orthohantavirus'' first identified in 1993 in Louisiana. and later confirmed by other investigators. In 1996, the marsh rice rat was identified as the natural reservoir of the virus, indicating the virus to be widespread throughout the Southeastern United States. BAYV infection causes hantavirus pulmonary syndrome (HPS) and represents the second most common hantavirus in the United States behind the ''Sin Nombre orthohantavirus ''Sin Nombre orthohantavirus'' (SNV) (from Spanish, meaning "without a name") is the prototypical etiologic agent of hantavirus cardiopulmonary syndrome (HCPS).

Bayou Virus Louisiana
In usage in the Southern United States, a bayou () is a body of water typically found in a flat, low-lying area. It may refer to an extremely slow-moving stream, river (often with a poorly defined shoreline), marshy lake, wetland, or creek. They typically contain brackish water highly conducive to fish life and plankton. Bayous are commonly found in the Gulf Coast region of the southern United States, especially in the Mississippi River Delta, though they also exist elsewhere. A bayou is often an anabranch or minor braid of a braided channel that is slower than the mainstem, often becoming boggy and stagnant. Though fauna varies by region, many bayous are home to crawfish, certain species of shrimp, other shellfish, catfish, frogs, toads, salamanders, newts, American alligators, American crocodiles, herons, lizards, turtles, tortoises, spoonbills, snakes, and leeches, as well as many other species. Etymology The word entered American English via Louisiana French in Louisiana a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catacamas Virus
Catacamas virus is a single-stranded, enveloped novel RNA virus in the genus ''Orthohantavirus'' of the order ''Bunyavirales'' isolated in '' Oryzomys couesi'' near the town of Catacamas in eastern Honduras. It is a member virus of ''Bayou orthohantavirus''. Natural reservoir Catacamas virus was isolated from ''Oryzomys couesi'' and none of 41 other rodents that were also trapped near the town of Catacamas. The finding represents the first time a hantavirus species has been found in Honduras. Virology Analysis of nucleotide and amino acid sequence data indicated that this hantaviral strain is phylogenetically most closely related to ''Bayou orthohantavirus'' which is associated with the marsh rice rat ('' Oryzomys palustris'') in the southeastern United States.Mary L. Milazzo, Maria N.B. Cajimat, Hannah E. Romo, Jose G. Estrada-Franco, L. Ignacio Iñiguez-Dávalos, Robert D. Bradley, and Charles F. Fulhorst.

Orthohantavirus
''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; howeve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marsh Rice Rat
The marsh rice rat (''Oryzomys palustris'') is a semiaquatic North American rodent in the family Cricetidae. It usually occurs in wetland habitats, such as swamps and salt marshes. It is found mostly in the eastern and southern United States, from New Jersey and Kansas south to Florida and northeasternmost Tamaulipas, Mexico; its range previously extended further west and north, where it may have been a commensal in corn-cultivating communities. Weighing about , the marsh rice rat is a medium-sized rodent that resembles the common black and brown rat. The upperparts are generally gray-brown, but are reddish in many Florida populations. The feet show several specializations for life in the water. The skull is large and flattened, and is short at the front. John Bachman discovered the marsh rice rat in 1816, and it was formally described in 1837. Several subspecies have been described since the 1890s, mainly from Florida, but disagreement exists over their validity. The Florida Key ...

Natural Reservoir
In infectious disease ecology and epidemiology, a natural reservoir, also known as a disease reservoir or a reservoir of infection, is the population of organisms or the specific environment in which an infectious pathogen naturally lives and reproduces, or upon which the pathogen primarily depends for its survival. A reservoir is usually a living host of a certain species, such as an animal or a plant, inside of which a pathogen survives, often (though not always) without causing disease for the reservoir itself. By some definitions a reservoir may also be an environment external to an organism, such as a volume of contaminated air or water. Because of the enormous variety of infectious microorganisms capable of causing disease, precise definitions for what constitutes a natural reservoir are numerous, various, and often conflicting. The reservoir concept applies only for pathogens capable of infecting more than one host population and only with respect to a defined target popu ...

Southeastern United States
The Southeastern United States, also referred to as the American Southeast or simply the Southeast, is a geographical region of the United States. It is located broadly on the eastern portion of the southern United States and the southern portion of the eastern United States. It comprises at least a core of states on the lower East Coast of the United States and eastern Gulf Coast. Expansively, it reaches as far north as West Virginia and Maryland (bordered to north by the Ohio River and Mason–Dixon line), and stretching as far west as Arkansas and Louisiana. There is no official U.S. government definition of the region, though various agencies and departments use different definitions. Geography The U.S. Geological Survey considers the Southeast region to be the states of Alabama, Florida, Georgia, Arkansas, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, and Tennessee, plus Puerto Rico and the United States Virgin Islands.

Hantavirus Pulmonary Syndrome
Hantavirus pulmonary syndrome (HPS) is one of two potentially fatal syndromes of zoonotic origin caused by species of hantavirus. These include Black Creek Canal virus (BCCV), New York orthohantavirus (NYV), Monongahela virus (MGLV), '' Sin Nombre orthohantavirus'' (SNV), and certain other members of hantavirus genera that are native to the United States and Canada. Specific rodents are the principal hosts of the hantaviruses including the hispid cotton rat (''Sigmodon hispidus'') in southern Florida, which is the principal host of Black Creek Canal virus. The deer mouse (''Peromyscus maniculatus'') in Canada and the Western United States is the principal host of Sin Nombre virus. The white-footed mouse (''Peromyscus leucopus'') in the eastern United States is the principal host of New York virus. In South America, the long-tailed mouse (''Oligoryzomys longicaudatus'') and other species of the genus ''Oligoryzomys'' have been documented as the reservoir for Andes virus. ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
