| avian erythroblastosis virus | <virology> Group of C type RNA tumour viruses (Oncovirinae) that cause various leukaemias and other tumours in birds. The acute leukaemia viruses, that are replication defective and require helper viruses, include avian erythroblastosis (AEV), myeloblastosis (AMV) and myelo cytomatosis viruses. AEV carries two transforming genes, v erbA and v erbB, the cellular homologue of the latter is the structural gene for the epidermal growth factor receptor. AMV carries v myb and causes a myeloid leukaemia, avian myelocytomatosis virus carries v myc. The avian lymphatic leukaemia viruses (ALV) are also Retroviridae but are replication competent and induce neoplasia only after several months, they often occur in conjunction with replication defective leukaemia viruses.

| erythroblastosis, foetal | Haemolytic anaemia of the foetus or newborn infant, caused by the transplacental transmission of maternally formed antibody, usually secondary to an incompatibility between the blood group of the mother and that of her offspring. (12 Dec 1998) |
| erythroblastosis foetalis | <haematology> A condition which develops in the foetus due to an incompatibility between the mother's blood type (RH factor) and the baby's. Maternal antibodies, which enter the foetal circulation during delivery attack the baby's red blood cells leading to haemolysis (rupture of the cells). Symptoms include an infant with an enlarged liver and spleen, swelling, jaundice and anaemia. (27 Sep 1997) |
