| lead anaemia | Anaemia associated with poisoning from lead; thought to result from a defect in synthesis of haemoglobin based on the failure of iron being combined in the porphyrin ring. (05 Mar 2000) |
| Lederer's anaemia | An obsolete eponym for a form of acute acquired haemolytic anaemia associated with abnormal haemolysins and sometimes with haemoglobinuria. (05 Mar 2000) |
| leukoerythroblastic anaemia | <haematology> Any anaemia condition which arises from a space occupying lesion in the bone marrow.

Origin: Gr. Haima = blood (27 Sep 1997) |
| local anaemia | Anaemia resulting from a decreased supply of blood to a part, as in the occlusion of a vessel. (05 Mar 2000) |
| abelson leukaemia virus | A defective murine leukaemia virus capable of transforming lymphoid cells and producing a rapidly progressing lymphoid leukaemia after superinfection with friend, moloney, or rauscher virus. (12 Dec 1998) |
| Abelson murine leukaemia virus | A retrovirus belonging to the Type C retrovirus group subfamily (family Oncovirinae) which is associated with leukaemia and produces in vitro transformation of mouse cells. (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) |
