reticuloendotheliosis

(rĭ-tĭk′yə-lō-ĕn′dō-thē′lē-ō′sĭs)
n.
Proliferation of the reticuloendothelium in any organ or tissue.

reticuloendotheliosis

[ritik′yəlō·en′dōthē′lē·ō′sis]
an abnormal condition characterized by increased growth and proliferation of the cells of the reticuloendothelial system. See also reticuloendothelial system.

reticuloendotheliosis

a superseded term for neoplasia of hemopoietic precursors. See also blast form of erythremic myelosis.

avian reticuloendotheliosis
a group of diseases of poultry caused by the REV group of retroviruses, and includes a chronic neoplastic disease of turkeys and chickens, a runting disease in chickens accidentally injected with the virus, and possibly an acute reticulum cell neoplasia. The chronic neoplasia is manifested by nodular tumors in visceral organs.
feline reticuloendotheliosis
leukemic reticuloendotheliosis
leukemia marked by splenomegaly and by an abundance of large, mononuclear abnormal cells with numerous, irregular cytoplasmic projections that give them a flagellated or hairy appearance in the bone marrow, spleen, liver and peripheral blood; called also hairy-cell leukemia.

22-26) Avian leukosis virus causes B-cell lymphomas mainly in gallinaceous poultry, and reticuloendotheliosis virus has been associated with either B- or T-cell lymphomas in gallinaceous birds, geese, and a European starling (Sturnus vulgaris).
Several viral diseases can present with a marked lymphocytic leukocytosis such as avian leukosis virus, reticuloendotheliosis virus, and Marek disease, (10-14) but they are not generally associated with a strong heterophilic leukocytosis.
As in the cases with CPV, CNPV, and HGPV, genetic analysis of F1PV revealed an absence of 3 corresponding FPV open reading frames (ORF199, 200, and 202) and an absence of any reticuloendotheliosis virus (REV) sequences in this region.
3-kb PstI-HindIII fragment of the genome of HGP isolate revealed very high homology (99% identities) with canary poxvirus (CNPV) ORF266-274, and like CNPV, homologs of 3 FWPV ORFs (199, 200, and 202) including any reticuloendotheliosis virus (REV) sequences are not present in the genome of HGP isolate.
Several novel criteria have been tested to assist in the differential diagnosis of tumors induced by Marek's disease virus (MDV) from those induced by avian leukosis virus (ALV) and reticuloendotheliosis virus (REV).
