Avian Lymphomatosis as a Neoplastic Disease

Avian Neoplastic Diseases

Neoplastic diseases: Marek's disease, avian leukosis and reticuloendotheliosis.

The commercially important neoplastic diseases of poultry are Marek's disease, which is caused by a herpesvirus, and the avian leukoses and reticuloendotheliosis, which are caused by retroviruses. These diseases are responsible for economic loss due to both mortality and depressed performance. Marek's disease virus (MDV) and avian leukosis viruses (ALVs) are prevalent throughout the world, and ...

Electron microscopy of avian lymphomatosis virus propagated in tissue culture.

Viruses isolated from avian erythroblastosis and myeloblastosis have been extensively investigated with the electron microscope (3-5, 8, 11, 1~). However, avian lymphomatosis virus has been studied by electron microscopy only in infected tissue sections (7), although a particulate component has been reported in the plasma of infected fowl (13). Wi th the successful cultivation of the lymphomato...

Lymphomatosis cerebri Presenting as a Recurrent Leukoencephalopathy

A 29-year-old immunocompetent woman was admitted in 2006 with ataxia, limb weakness, generalized dystonia, and vertical diplopia that developed after a febrile episode. Brain magnetic resonance imaging (MRI) revealed the presence of extensive periventricular white matter lesions that did not enhance after gadolinium injection. As low titers of cytomegalovirus-IgM antibodies were found in the se...

Comparison of an avian osteopetrosis virus with an avian lymphomatosis virus by RNA-DNA hybridization.

Myeloblastosis-associated virus (MAV)-2(0), a virus which was derived from avian myeloblastosis virus and induced a high incidence of osteopetrosis, was compared with avian lymphomatosis virus 5938, a recent field isolate which induced a high incidence of lymphomatosis. The following information was obtained. (i) MAV-2(0) induced osteopetrosis, nephroblastoma, and a very low incidence of hepato...
