| viral hepatitis type E | Hepatitis caused by a nonenveloped, single-stranded, positive-sense RNA virus 27-34 nm in diameter, unrelated to other hepatitis; it is the principal cause of enterically transmitted, waterborne, epidemic NANB hepatitis occurring primarily in Asia and Africa. Synonym: hepatitis E. (05 Mar 2000) |
|---|---|
| viral hepatitis vaccines | Any vaccine raised against any virus or viral derivative that causes hepatitis. (12 Dec 1998) |
| viral infection | The successful invasion, establishment and growth of viruses in the tissues of the host. (27 Sep 1997) |
| viral interference | A phenomenon in which infection by a first virus results in resistance of cells or tissues to infection by a second, unrelated virus. (12 Dec 1998) |
| viral load | The number of viral particles (usually HIV) in a sample of blood plasma. HIV viral load is increasingly employed as a surrogate marker for disease progression. It is measured by PCR and bDNA tests and is expressed in number of HIV copies or equivalents per millilitre. (09 Oct 1997) |
| viral meningitis | <pathology> A viral form of infection that is seen most often in those under 30 years of age. Peak time for infection is in late summer. Majority of cases are caused by the Coxsackie and echovirus. (27 Sep 1997) |
| viral myocarditis | <cardiology, virology> Inflammation of the heart muscle that is caused by an infection with a virus. Coxsackie B is most common in the U.S.A., but Coxsackie A, influenza, rubeola, rubella, Adenovirus, HIV and echovirus can all cause myocarditis. (27 Sep 1997) |
| viral oncogene | <molecular biology> A viral gene that contributes to cancer development in vertebrate hosts. (09 Oct 1997) |
| viral pericarditis | Pericarditis due to a viral infection. (05 Mar 2000) |
| viral physiology | Biological processes and activities of viruses. (12 Dec 1998) |
| viral pneumonia | <radiology> Common agents: RSV, parainfluenza, adenovirus, influenza (12 Dec 1998) |
| viral probe | A nucleic acid fragment, labelled by a radioisotope, biotin, etc., that is complementary to a sequence in another nucleic acid (fragment) and that will, by hydrogen binding to the latter, locate or identify it and be detected; a diagnostic technique based on the fact that every species of microbe possesses some unique nucleic acid sequences which differentiate it from all others, and thus can be used as identifying markers or "fingerprints." (05 Mar 2000) |
| viral strand | See: replicative form. (05 Mar 2000) |
| viral therapy | The use of genetically altered virus particles for delivering genes to specific sites for the purpose of therapy. (05 Mar 2000) |
| viral transformation | <oncology, virology> Malignant transformation of an animal cell in culture, induced by a virus. (18 Nov 1997) |
