| african swine fever-like viruses | An unnamed, unclassified genus of DNA viruses with a single species: african swine fever virus. (12 Dec 1998) |
| alpha viruses | <virology> These are the major viruses in the Togavirus group and include eastern and western equine encephalitis viruses, the Sindbis virus and the Semliki Forest virus. The last two viruses are being researched as vectors for expressing heterologous genes. (09 Oct 1997) |
| animal viruses | Virus's occurring in man and other animals, causing inapparent infection or producing disease. (05 Mar 2000) |
| bunyamwera group viruses | A large group of viruses from many parts of the world assigned to the bunyavirus genus of the family bunyaviridae. They are transmitted by mosquitoes and infect humans in some areas. This group contains the type species of the genus, bunyamwera virus. (12 Dec 1998) |
| california group viruses | A group of viruses in the bunyavirus genus of the bunyaviridae family. They are found in temperate and arctic regions and each is closely associated with a single species of vector mosquito. The vertebrate hosts are usually small mammals but several virus species infect humans. (12 Dec 1998) |
| Capim viruses | A serologic group of the genus Bunyavirus, the type species of which is Capim virus. (05 Mar 2000) |
| pappataci fever viruses | An unclassified serologic group of arboviruses morphologically like Bunyavirus but antigenically unrelated, transmitted by Phlebotomus papatasi (sandfly) and causing phlebotomus fever; there are 20 strains, including Icoarachi and Itaporanga. Synonym: pappataci fever viruses, sandfly fever viruses. (05 Mar 2000) |
| mammary tumour viruses, mouse | The type species of mammalian type b retroviruses (retroviruses type b, mammalian) commonly latent in mice. It causes mammary adenocarcinoma when in a genetically susceptible strain of mice and when the appropriate hormonal influences operate. (12 Dec 1998) |
| parainfluenza viruses | Virus's of the genus Paramyxovirus, of four types: type 1 (haemadsorption virus type 2), which includes sendai virus, causes acute laryngotracheitis in children and occasionally adults; type 2 (croup-associated virus) is associated especially with acute laryngotracheitis or croup in young children and minor upper respiratory infections in adults; type 3 (haemadsorption virus type 1; shipping fever virus) has been isolated from small children with pharyngitis, bronchiolitis, and pneumonia, and causes occasional respiratory infection in adults; bovine strains have been isolated from cattle with shipping fever, and the virus has also been isolated from sheep; type 4 has been isolated from a very few children with minor respiratory illness. (05 Mar 2000) |
| reassortant viruses | Viruses containing two or more pieces of nucleic acid (segmented genome) from different parents. Such viruses are produced in cells coinfected with different strains of a given virus. (12 Dec 1998) |
| vertebrate viruses | Viruses infecting man and other vertebrates. (12 Dec 1998) |
| viruses | <microbiology, virology> An ultra-microscopic micro-organism, parasitic within living cells and of which many can cause disease in humans. They consist of a strand of nucleic acid (DNA or RNA) that contains genetic instructions concerning viral reproduction that is enveloped by a protein coat. Cellular rupture (and death) liberates the newly from viruses. (13 Oct 1997) |
| viruses, unclassified | Viruses whose taxonomic relationships have not been established. (12 Dec 1998) |
| respiratory syncytial viruses | A group of viruses in the pneumovirus genus causing respiratory infections in various mammals. Humans and cattle are most affected but infections in goats and sheep have also been reported. (12 Dec 1998) |
