Coronavirus Torovirus Virus classification involves naming and placing viruses into a taxonomic system. ... An RNA virus is a virus that either uses RNA as its genetic material, or whose genetic material passes through an RNA intermediate during replication. ... Families Arteriviridae Coronaviridae Roniviridae The Nidovirales are an order of viruses with vertebrate hosts. ... Coronavirus is a genus of animal virus belonging to the family Coronaviridae. ...
Coronaviruses are enveloped, single stranded, positive-sense RNA viruses (27-31kb) with club-shaped surface about 120-160 nm in diameter that resemble a “corona”. Both 5' and 3' ends of the genome have a cap and poly (A) tract respectively. The envelope consists of two viral-specified structural glycoproteins S and M. Glycoprotein S is located on the outer membrane of the envelope and is responsible for the club-shaped projections. On the other hand, glycoprotein M is a transmembrane molecule and is located on the inner part of the envelope. Another important structural protein is the phosphoprotein N which is responsible for the helical symmetry of the nucleocapsid that encloses the genomic RNA. Ribonucleic acid (RNA) is a nucleic acid polymer consisting of nucleotide monomers, that acts as a messenger between DNA and ribosomes, and that is also responsible for making proteins out of amino acids. ... Front of an envelope mailed in the U.S. in 1906 contains postage stamp and address. ... A glycoprotein is a macromolecule composed of a protein and a carbohydrate (an oligosaccharide). ... A representation of the 3D structure of myoglobin, showing coloured alpha helices. ... Phosphoproteins are a group of proteins which are chemically attached to a substance containing phosphoric acid. ...
The Coronaviridae are a family of viruses, including the following genera: Groups I: dsDNA viruses II: ssDNA viruses III: dsRNA viruses IV: (+)ssRNA viruses V: (-)ssRNA viruses VI: ssRNA-RT viruses VII: dsDNA-RT viruses A virus (from the Latin noun virus, meaning toxin or poison) is a microscopic particle (ranging in size from 20 - 300 nm) that can infect the...
Genus Coronavirus; type species: Infectious bronchitis virus
Genus Torovirus; type species: Equine torovirus
Coronavirus is a genus of animal virus belonging to the family Coronaviridae. ...
Transmission
Coronaviruses are transmitted by faecal-oral route or by aerosols of respiratory secretions. Many diseases can be passed when the stool (or remnants thereof) of one host ends up in someone elses mouth. ...
Pathogenesis
Coronaviruses infect a wide range of mammals and birds and occur worldwide. Although, most diseases are mild, sometimes they can cause more severe situations in humans, like for example an infection of the respiratory tract including Severe Acute Respiratory Syndrome (SARS). They can also cause enteric infections in very young infants and in rare situations neurological syndrome.

Severe acute respiratory syndrome or SARS is a respiratory disease in humans which is caused by the SARS coronavirus. ...
