Blicbavirus
''White bream virus'' is a species of virus. It is the sole species in the subgenus ''Blicbavirus'', which is in the genus ''Bafinivirus''. It was first isolated from white bream (''Blicca bjoerkna'') in Germany. It is a bacilliform (rod-shaped) positive-sense single-stranded RNA virus Positive-strand RNA viruses (+ssRNA viruses) are a group of related viruses that have positive-sense, single-stranded genomes made of ribonucleic acid. The positive-sense genome can act as messenger RNA (mRNA) and can be directly translated into .... References Nidovirales Zoonoses {{virus-stub ...

Electron Micrograph
A micrograph or photomicrograph is a photograph or digital image 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 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 ''photomicroscopy''. At a basic level, photomicroscopy may be performed simply by connecting a camera to a microscope, t ...

White Bream
''Blicca bjoerkna'', alternatively called the white bream or the silver bream, is a European species of freshwater fish in the family Cyprinidae. Distribution ''Blicca bjoerkna'' is distributed across most of Europe and in adjacent Western Asia. The natural distribution, though, excludes peripheral areas such as northern Sweden, northern Finland and Norway, and most parts of the British Isles (except Southern England), as well as the Iberian and Italian peninsulas. Introduced populations occur also in Spain and Italy, for instance. The Asian distribution is in the Caspian Sea and Aral Sea basins and in Anatolian Black Sea drainages. Description Small silver bream are very similar in overall appearance to the immature common, or bronze bream, ''Abramis brama'', but can be distinguished by their larger scales. Counting the scale rows from the front of the dorsal fin to the lateral line and including the lateral line scale, is the most reliable first step in determining the spe ...

Bacilliform
A bacillus (), also called a bacilliform bacterium or often just a rod (when the context makes the sense clear), is a rod-shaped bacterium or archaeon. Bacilli are found in many different taxonomic groups of bacteria. However, the name ''Bacillus'', capitalized and italicized, refers to a specific genus of bacteria. The name Bacilli, capitalized but not italicized, can also refer to a less specific taxonomic group of bacteria that includes two orders, one of which contains the genus ''Bacillus''. When the word is formatted with lowercase and not italicized, 'bacillus', it will most likely be referring to shape and not to the genus at all. Bacilliform bacteria are also often simply called rods when the bacteriologic context is clear. Bacilli usually divide in the same plane and are solitary, but can combine to form diplobacilli, streptobacilli, and palisades. * Diplobacilli: Two bacilli arranged side by side with each other. * Streptobacilli: Bacilli arranged in chains. * Coccobac ...

Positive-sense Single-stranded RNA Virus
Positive-strand RNA viruses (+ssRNA viruses) are a group of related viruses that have positive-sense, single-stranded genomes made of ribonucleic acid. The positive-sense genome can act as messenger RNA (mRNA) and can be directly translated into viral proteins by the host cell's ribosomes. Positive-strand RNA viruses encode an RNA-dependent RNA polymerase (RdRp) which is used during replication of the genome to synthesize a negative-sense antigenome that is then used as a template to create a new positive-sense viral genome. Positive-strand RNA viruses are divided between the phyla ''Kitrinoviricota'', ''Lenarviricota'', and ''Pisuviricota'' (specifically classes ''Pisoniviricetes'' and '' Stelpavirictes'') all of which are in the kingdom '' Orthornavirae'' and realm '' Riboviria''. They are monophyletic and descended from a common RNA virus ancestor. In the Baltimore classification system, +ssRNA viruses belong to Group IV. Positive-sense RNA viruses include pathogens s ...

Nidovirales
''Nidovirales'' is an order of enveloped, positive-strand RNA viruses which infect vertebrates and invertebrates. Host organisms include mammals, birds, reptiles, amphibians, fish, arthropods, molluscs, and helminths. The order includes the families ''Coronaviridae'', ''Arteriviridae, Roniviridae,'' and ''Mesoniviridae''. Member viruses have a viral envelope and a positive-sense, single-stranded RNA genome which is capped and polyadenylated. Nidoviruses are named for the Latin ''nidus'', meaning nest, as all viruses in this order produce a 3' co-terminal nested set of subgenomic mRNAs during infection. Virology Structure Nidoviruses have a viral envelope and a positive-sense, single-stranded RNA genome which is capped and polyadenylated. The group expresses structural proteins separately from the nonstructural ones. The structural proteins are encoded at the 3’ region of the genome and are expressed from a set of subgenomic mRNAs. Member viruses encode one main protei ...
