Infrequent involvement of c-fos in avian leukosis virus-induced nephroblastoma.

The oncogenic effects of nontransforming viruses from avian myeloblastosis virus.

Standard avian myeloblastosis virus (AMV), BAI strain A, causes myeloblastosis, osteopetrosis, lymphoid leukosis, and nephroblastoma in chickens. In this investigation, several leu kosis viruses of subgroups A and B were isolated (rom standard AMV and characterized. A subgroup A virus derived from an AMV-induced lymphoma of a Japanese quail was isolated, and it induced a high incidence of osteo...

Serologic profile of avian leukosis virus subgroup-J, Mycoplasma gallisepticum and Mycoplasma synoviae in broiler grandparent flocks of Iran.

  Avian Leukosis Virus Subgroup-J (ALV-J). Mycoplasma gallisepticum (MG) and MycopJasma synviae (MS) are important pathogens in chickens that cause severe economical losses in poultry industry throughout the world. Seven broiler grandparent flocks of Iran (six broiler strains) were sampled randomly at the ages of 8-63 wk (100 samples from each flock) for antibody detection to ALV-J, MG, and MS ...

Detection of avian leukosis virus (ALV) in albumen of Shiraz commercial and local layer flocks using ELISA and RT-PCR

Avian leukosis viruses (ALVS) cause different types of tumours in poultry and can affect the health and egg production of the birds. To investigate the presence of the virus in chicken layer flocks in Shiraz, 222 egg albumen from local layer breeder (25 eggs), local layer grand parent (30 eggs), broiler breeder (60 eggs), commercial layer (46 eggs) and broiler grand parent (61 eggs) were tested...
