(4-6) In poultry, lymphoid tumors have been associated with herpesviruses (Marek's disease) and retroviruses (lymphoid
leukosis and reticuloendotheliosis).
We highlight the importance of bovine
leukosis as an immunosuppressive agent predisposing animals to atypical and fatal infections.
In the late 1960s and early 1970s it was discovered that enzootic bovine
leukosis, a disease recognized to cause lymphoid tumor development for over a century [45,46], was caused by a novel virus [1-4].

leukosis viruses," Virology, vol.
BIC was first identified in avian
leukosis virus-induced B lymphomagenesis as a collaborator with c-myc even though it is a nonprotein-coding RNA due to the lack of a large open reading frame (ORF) [29-31].

Hematologic malignancies (lymphoma,
leukosis, etc.) were found in six patients.
The eradication experience of enzootic bovine
leukosis from Lithuania.
These chicken lines have been selected and maintained for decades after exposure to avian
leukosis virus and MD virus; line 6.3 being resistant, and line 7.2 being sensitive to these pathogens at the Avian Disease and Oncology Laboratory (ADOL), of the Agriculture Research Service, United States Department of Agriculture (USDA, East Lansing, MI, USA).
