Aphthovirus
''Aphthovirus'' (from the Greek , , 'vesicles in the mouth') is a viral genus of the family ''Picornaviridae''. Aphthoviruses infect split-hooved animals, and include the causative agent of foot-and-mouth disease, foot-and-mouth disease virus (FMDV). There are seven FMDV serotypes: A, O, C, SAT 1, SAT 2, SAT 3 and Asia 1, and four non-FMDV serotypes belonging to three additional species Bovine rhinitis A virus (BRAV), Bovine rhinitis B virus (BRBV) and Equine rhinitis A virus (ERAV). Taxonomy The genus contains the following species, listed by scientific name: * ''Aphthovirus bogeli'', Bovine rhinitis A virus * ''Aphthovirus burrowsi'', Equine rhinitis A virus * ''Aphthovirus reedi'', Bovine rhinitis B virus * ''Aphthovirus vesiculae'', Foot-and-mouth disease virus Structure Aphthoviruses are non-enveloped and have an icosahedral capsid with a diameter of around 27 to 30 nm. The assembled viral capsid contains a single copy of the RNA genome and 60 copies of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronmicrograph
A micrograph is an image, captured photographically or digitally, taken through a microscope or similar device to show a magnified image of an object. This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times. Micrography is the practice or art of using microscopes to make photographs. A photographic micrograph is a photomicrograph, and one taken with an electron microscope is an electron micrograph. A micrograph contains extensive details of microstructure. A wealth of information can be obtained from a simple micrograph like behavior of the material under different conditions, the phases found in the system, failure analysis, grain size estimation, elemental analysis and so on. Micrographs are widely used in all fields of microscopy. Types Photomicrograph A light micrograph or photomicrograph is a micrograph prepared using an optical microscope, a process referred to as ''ph ...
