| lymphatic leukaemia | <haematology, oncology> An acute form of childhood leukaemia characterised by the development of abnormal cellsdevelop in the bone marrow and lymphoblasts are found in blood-formingtissues. A type of chronic leukaemia found most often in the elderly, it is characterised by the presence of mature lymphocytes in the blood. Origin: Gr. Haima = blood (13 Nov 1997) |

| lymphoblastic leukaemia | Acute lymphocytic leukaemia in which the abnormal cells are chiefly (or almost totally) blast forms of the lymphocytic series, or in which unusually large numbers of the immature forms occur in association with adult lymphocytes. (05 Mar 2000) |

| adeno-associated virus | <virology> A genus of viruses in the family Parvoviridae which are all defective viruses (unable to replicate by themselves) and depend on the co-infection of their host cell by other, nondefective viruses to help them replicate. (09 Oct 1997) |
| adenoidal-pharyngeal-conjunctival virus | <virology> An icosahedral (20-sided) virus that contains DNA, there are over 40 different adenovirus varieties, some of which cause the common cold. (10 May 1997) |
| adenosatellite virus | <virology> A genus of viruses in the family Parvoviridae which are all defective viruses (unable to replicate by themselves) and depend on the co-infection of their host cell by other, nondefective viruses to help them replicate. (09 Oct 1997) |
| african horse sickness virus | A species of orbivirus that causes disease in horses, mules, and donkeys. (12 Dec 1998) |
| african swine fever virus | The lone species of the genus african swine fever-like viruses. The virus causes a fatal disease among domestic pigs in africa and a less virulent infection in europe. The virus is present in soft ticks (ornithodoros moubata), warthogs, or domestic pigs. Originally listed as a species of iridoviridae, the virus exhibits some similarities to poxviridae but its differences warranted placement in a separate genus of an, as yet unknown, family. (12 Dec 1998) |
| AIDS-related virus | An obsolete term for human immunodeficiency virus. (05 Mar 2000) |
| Akabane virus | A virus of the genus Bunyavirus, family Bunyaviridae, causing abortion in cattle and congenital arthrogryposis and hydranencephaly in bovine foetuses in Israel, Japan, and Australia; it is transmitted by mosquitoes. (05 Mar 2000) |
| akr virus | A murine leukaemia virus isolated from spontaneous leukaemia in akr strain mice. (12 Dec 1998) |
| aleutian mink disease virus | A species of parvovirus that causes a disease in mink, mainly those homozygous for the recessive aleutian gene which determines a desirable coat colour. (12 Dec 1998) |
| alfalfa mosaic virus | The type-species of the genus alfamovirus that is non-persistently transmitted by aphids. (12 Dec 1998) |
| amphotropic virus | An oncornavirus that does not produce disease in its natural host but does replicate in tissue culture cells of the host species and also in cells from other species. (05 Mar 2000) |
