Flexal Virus
''Flexal mammarenavirus'' (also known as the Flexal virus or FLEV, and previously known by the laboratory code BeAn 293022) is a mammarenavirus: an arenavirus with a mammalian host. It was first found in semiaquatic rodents of the genus Oryzomys in tropical forest in the Pará area of Brazil Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and Latin America. At and with over 217 million people, Brazil is the world's fifth-largest country by area .... It is a member of Clade A of the Tacaribe (or "New World") serocomplex of the family ''Arenaviridae''. Laboratory workers infected by Flexal virus have exhibited febrile illness.Flexal virus is listed as a UN 2814 Category A infectious substance.

Mammarenavirus
''Mammarenavirus'' is a genus of viruses in the family '' Arenaviridae''. The name is a portmanteau of mammal and the former name ''Arenavirus'', and differentiates it from the reptile-associated '' Reptarenavirus''. ''Arenavirus'' comes from the Latin (sand) for the sandy appearance of the virions. Taxonomy The following species are recognized: * '' Allpahuayo mammarenavirus'' * '' Alxa mammarenavirus'' * '' Argentinian mammarenavirus'' * '' Bear Canyon mammarenavirus'' * '' Brazilian mammarenavirus'' * '' Cali mammarenavirus'' * '' Chapare mammarenavirus'' * '' Chevrier mammarenavirus'' * '' Cupixi mammarenavirus'' * '' Flexal mammarenavirus'' * '' Gairo mammarenavirus'' * '' Guanarito mammarenavirus'' * ''Ippy mammarenavirus'' * '' Kitale mammarenavirus'' * '' Lassa mammarenavirus'' * '' Latino mammarenavirus'' * '' Loei River mammarenavirus'' * '' Lujo mammarenavirus'' * '' Luna mammarenavirus'' * '' Lunk mammarenavirus'' * ''Lymphocytic choriomeningitis mammarenavirus ...

Arenavirus
An arenavirus is a bisegmented ambisense RNA virus that is a member of the family ''Arenaviridae''. These viruses infect rodents and occasionally humans. A class of novel, highly divergent arenaviruses, properly known as reptarenaviruses, have also been discovered which infect snakes to produce inclusion body disease. At least eight arenaviruses are known to cause human disease. The diseases derived from arenaviruses range in severity. Aseptic meningitis, a severe human disease that causes inflammation covering the brain and spinal cord, can arise from the lymphocytic choriomeningitis virus. Hemorrhagic fever syndromes, including Lassa fever, are derived from infections such as Guanarito virus, Junin virus, Lassa virus, Lujo virus, Machupo virus, Sabia virus, or Whitewater Arroyo virus. Because of the epidemiological association with rodents, some arenaviruses and bunyaviruses are designated as roboviruses. Structure Viewed in cross-section, arenaviruses contain grainy parti ...

Oryzomys
''Oryzomys'' is a genus of semiaquatic rodents in the tribe Oryzomyini living in southern North America and far northern South America. It includes eight species, two of which—the marsh rice rat (''O. palustris'') of the United States and '' O. couesi'' of Mexico and Central America—are widespread; the six others have more restricted distributions. The species have had eventful taxonomic histories, and most species were at one time included in the marsh rice rat; additional species may be recognized in the future. The name ''Oryzomys'' was established in 1857 by Spencer Fullerton Baird for the marsh rice rat and was soon applied to over a hundred species of American rodents. Subsequently, the genus gradually became more narrowly defined until its current contents were established in 2006, when ten new genera were established for species previously placed in ''Oryzomys''. Species of ''Oryzomys'' are medium-sized rats with long, coarse fur. The upperparts are gray ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Forest
Tropical forests (a.k.a. jungle) are forested landscapes in tropical regions: ''i.e.'' land areas approximately bounded by the tropic of Cancer and Capricorn, but possibly affected by other factors such as prevailing winds. Some tropical forest types are difficult to categorise. While forests in temperate areas are readily categorised on the basis of tree canopy density, such schemes do not work well in tropical forests. There is no single scheme that defines what a forest is, in tropical regions or elsewhere.Anatoly Shvidenko, Charles Victor Barber, Reidar Persson et al. 2005 "Millennium Ecosystem Assessment." Ecosystems and human wellbeing: a framework for assessment Washington, DC: Island Press Because of these difficulties, information on the extent of tropical forests varies between sources. However, tropical forests are extensive, making up just under half the world's forests. The tropical domain has the largest proportion of the world’s forests (45 percent), followed by ...

Biological Hazard
A biological hazard, or biohazard, is a biological substance that poses a threat to the health of living organisms, primarily humans. This could include a sample of a microorganism, virus or toxin that can adversely affect human health. A biohazard could also be a substance harmful to other animals. The term and its associated symbol are generally used as a warning, so that those potentially exposed to the substances will know to take precautions. The biohazard symbol was developed in 1966 by Charles Baldwin, an environmental-health engineer working for the Dow Chemical Company on the containment products. It is used in the labeling of biological materials that carry a significant health risk, including viral samples and used hypodermic needles. In Unicode, the biohazard symbol is U+2623 (). ANSI Z535/OSHA/ISO regulation Biohazardous safety issues are identified with specified labels, signs and paragraphs established by the American National Standards Institute (ANSI). ...
