| genes, structural, viral | DNA or RNA sequences that code for RNA and for the proteins required for the enzymatic and structural function of viral cells. (12 Dec 1998) |
|---|---|
| genes, viral | The hereditary material of viruses, consisting in all DNA and some RNA viruses of a single molecule of nucleic acid, and in some RNA viruses of several separate pieces of RNA. (12 Dec 1998) |
| genome, viral | The complete gene complement contained in a DNA or RNA molecule in a virus. (12 Dec 1998) |
| viral | Pertaining to, caused by or of the nature of virus. (18 Nov 1997) |
| viral alkaline nuclease | <enzyme> Has both exo and endonuclease activity Registry number: EC 3.1.- Synonym: hsv type 1 alkaline nuclease, herpes simplex virus type I alkaline nuclease, alkaline nuclease, herpes simplex virus (26 Jun 1999) |
| viral antigen | Those antigens specified by the viral genome (often coat proteins) that can be detected by a specific immunological response. Often of diagnostic importance. (18 Nov 1997) |
| viral core proteins | Proteins found mainly in icosahedral DNA and RNA viruses. They consist of proteins directly associated with the nucleic acid inside the nucleocapsid. (12 Dec 1998) |
| viral cystitis | Bladder inflammation due to a viral infection. (05 Mar 2000) |
| viral dysentery | Profuse watery diarrhoea due to, or thought to be due to, infection by a virus. (05 Mar 2000) |
| viral encephalomyelitis | An encephalomyelitis due to a neurotropic virus. (05 Mar 2000) |
| viral envelope | The outer structure that encloses the nucleocapsids of some viruses; may contain host material. (05 Mar 2000) |
| viral envelope proteins | Layers of protein which surround the capsid in animal viruses with tubular nucleocapsids. The envelope consists of an inner layer of lipids and virus specified proteins also called membrane or matrix proteins. The outer layer consists of one or more types of morphological subunits called peplomers which project from the viral envelope; this layer always consists of glycoproteins. (12 Dec 1998) |
| viral fusion proteins | Proteins, usually glycoproteins, found in the viral envelopes of a variety of viruses. They promote cell membrane fusion and thereby may function in the uptake of the virus by cells. (12 Dec 1998) |
| viral gastroenteritis | <pathology> An inflammatory condition of the intestines that results from an infection with a virus. Rotavirus is a common cause. Abdominal pain, diarrhoea, nausea and vomiting are common symptoms. (27 Sep 1997) |
| viral haemagglutination | The nonimmune agglutination of suspended red blood cells by certain of a wide range of otherwise unrelated viruses, usually by the virion itself but in some instances by products of viral growth, the species of erythrocyte agglutinated differing with the different viruses. See: haemagglutination inhibition. (05 Mar 2000) |
