| nairobi sheep disease viruses | A group of viruses of the genus nairovirus, transmitted by the ixodid ticks and producing a lethal gastroenteritis in sheep and goats, especially in africa. Though major veterinary pathogens, their effect on humans has not been firmly established. (12 Dec 1998) |

| defective viruses | Viruses which lack a complete genome so that they cannot completely replicate or cannot form a protein coat. Some are host-dependent defectives, meaning they can replicate only in cell systems which provide the particular genetic function which they lack. Others, called satellite viruses, are able to replicate only when their genetic defect is complemented by a helper virus. (12 Dec 1998) |
| swine influenza viruses | Strains of influenza virus type A which cause influenza of swine and can infect humans. (05 Mar 2000) |
| DNA tumour viruses | DNA viruses producing malignant tumours. Of the six major groupings of DNA viruses four contain members which are actually or potentially oncogenic: the adenoviridae, the herpesviridae, the papovaviridae, and the poxviridae. (12 Dec 1998) |
| DNA viruses | Viruses whose nucleic acid is DNA. (12 Dec 1998) |
| inclusion conjunctivitis viruses | Former name for Chlamydia trachomatis. (05 Mar 2000) |
| influenza viruses | Virus's of the family Orthomyxoviridae which cause influenza and influenza-like infections of humans and other animals; virus's included are influenza virus types A and B of the genus Influenzavirus, causing, respectively, influenza A and B, and influenza virus type C, which probably belongs to a separate genus and causes influenza C. (05 Mar 2000) |
| insect viruses | Viruses infecting insects, the largest family being baculoviridae. (12 Dec 1998) |
| oncogenic viruses | Viruses that produce tumours. (12 Dec 1998) |
| orphan viruses | Virus's, such as the enteric orphan virus's, which when originally found were not specifically associated with disease; a number of these have since been shown to be pathogenic. (05 Mar 2000) |
| Tacaribe complex of viruses | A group of arenaviruses that includes the antigenically interrelated arboviruses Amapari, Junin, Latino, Machupo, Parana, Pichinde, Tacaribe, and Tamiami. (05 Mar 2000) |
| tacaribe complex viruses | One of two groups of viruses in the arenavirus genus and considered part of the new world complex. It includes junin virus, pichinde virus, amapari virus, and machupo virus among others. They are the cause of human haemorrhagic fevers mostly in central and south america. (12 Dec 1998) |
| Tete viruses | A serologic group of the genus Bunyavirus, comprising a number of types. (05 Mar 2000) |
| thogoto-like viruses | A genus of the family orthomyxoviridae comprising tick-borne viruses occasionally infecting humans. Dhori and thogoto viruses were formerly thought to be members of bunyaviridae. Thogoto virus is the type species. (12 Dec 1998) |
| emerging viruses | In epidemiology, a class of viruses that have long infected humans or animals but now have the opportunity to attain epidemic proportions due to human encroachment on tropical rainforests, increased international travel, burgeoning populations in less developed countries, and, possibly, global warming. About two dozen viruses have been termed emergent, including haemorrhagic viruses such as Ebola, Marburg, and Hantaan; the rabies-like viruses Mokola and Duvenhage; rodent-borne Jinin and Lassa virus; and mosquito-borne dengue. Virologists speculate that the strain of HIV that causes AIDS may also fall into this category, having entered humans through contact with monkeys in central Africa, possibly having existed among monkey populations for some 50,000 years.
