Coronavirus 3' stem-loop II-like motif (s2m)SARS coronavirus: The SARS coronavirus, sometimes shortened to SARS-CoV, is the virus that causes severe acute respiratory syndrome (SARS). On April 16, 2003, following the outbreak of SARS in Asia and secondary cases elsewhere in the world, the World Health Organization (WHO) issued a press release stating that the coronavirus identified by a number of laboratories was the official cause of SARS.Timeline of the SARS outbreak: The following is a timeline of the 2002–04 outbreak of severe acute respiratory syndrome (SARS).Bovine coronavirus: Bovine coronavirus (BCV) is as a member of the Coronaviridae family which are enveloped, single-stranded, positive-sense RNA viruses with a club-shaped surface. Infection causes 'Calf Enteritis' and contributes to the 'Enzootic Pneumonia complex' in calves.Peplomer: A peplomer is a glycoprotein spike on a viral capsid or viral envelope. as cited in These protrusions will only bind to certain receptors on the host cell: they are essential for both host specificity and viral infectivity.Transmissible gastroenteritis coronavirus: Transmissible Gastroenteritis Coronavirus (TGEV) is a virus belonging to the family Coronaviridae, genus Alphacoronavirus, species Alphacoronavirus 1. TGEV are enveloped viruses with a positive-sense single-stranded RNA genome and a helical symmetry.Feline infectious peritonitis: frame|right|FIP-infected kidney showing inflammatory responseLower respiratory tract infection: Lower respiratory tract infection (LRTI), while often used as a synonym for pneumonia, can also be applied to other types of infection including lung abscess and acute bronchitis. Symptoms include shortness of breath, weakness, fever, coughing and fatigue.Pseudotyping: Pseudotyping is the process of producing viruses or viral vectors in combination with foreign viral envelope proteins. The result is a pseudotyped virus particle.Avian infectious bronchitis virus: Avian infectious bronchitis virus (IBV) is a coronavirus which infects chickens, causing the associated disease, infectious bronchitis (IB). It is a highly infectious avian pathogen which affects the respiratory tract, gut, kidney and reproductive systems of chickens.Plaque reduction neutralization test: The Plaque reduction neutralization test is used to quantify the titre of neutralising antibody for a virus.Cytopathic effectCats in the United States: Many different species of mammal can be classified as cats (felids) in the United States. These include domestic cat (both house cats and feral), of the species Felis catus; medium-sized wild cats from the genus Lynx; and big cats from the genera Puma and Panthera.Turkey coronavirus: Turkey coronaviruses are members of the family Coronaviridae that infect turkeys, especially poults, leading to gastrointestinal disease. Viruses include turkey enteritis virus and bluecomb disease virus.Lung receptor: Lung receptors sense irritation or inflammation in the bronchi and alveoli.Coles PhillipsProtein primary structure: The primary structure of a peptide or protein is the linear sequence of its amino acid structural units, and partly comprises its overall biomolecular structure. By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end.PSI-6130Symmetry element: A symmetry element is a point of reference about which symmetry operations can take place. In particular, symmetry elements can be centers of inversion, axes of rotation and mirror planes.Influenza virus matrix protein 2: Matrix protein 2 of Influenza virus is a single-spanning transmembrane protein. It is expressed on the infected cell surface and incorporated into virions where it is a minor component.NS3 (HCV): Nonstructural protein 3 (NS3), also known as p-70, is a viral nonstructural protein that is 70 kDa cleavage product of the hepatitis C virus polyprotein. It acts as a serine protease.Alanine aminopeptidase: Alanine aminopeptidase () is an enzyme that is used as a biomarker to detect damage to the kidneys, and that may be used to help diagnose certain kidney disorders. It is found at high levels in the urine when there are kidney problems.
