The epidemiology of avian lymphoid leukosis.

Avian lymphoid leukosis: Virus-like particles in kidney Cells

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...

Epidemiological features and pathological study of avian leukosis in turkeys’ flocks

AIM The purpose of this study was focused on the identification of tumor diseases in turkeys on the basis of a detailed description of epidemiological features, clinical signs, lesions, and histopathological changes. MATERIALS AND METHODS Outbreak of a tumor disease in turkeys was investigated in various regions of Eastern Algeria. Four turkeys' flocks aged from 17 weeks were affected, result...

Infection and Tumor Formation in Chickens By Avian Leukosis Virus

Lymphoid leukosis in chickens is a disease which arises from the result of complicated interaction between avian leukosis virus (ALV) as a pathogenic organism and chicken as a host. This report is intended to outline our present knowledge about genetic resistance of chickens in lymphoid leukosis. The defense of host in infectious disease could be considered dividing it into two: one as a workin...

On the mechanism of retrovirus-induced avian lymphoid leukosis: deletion and integration of the proviruses.

There is considerable evidence that infection by avian lymphoid leukosis viruses can led to tumor development in the target organ of the host. The mechanism by which virus-induced oncogenic transformation occurs, however, is not clearly understood. As a first step toward deciphering this process, we have characterized the proviruses of the lymphoid leukosis viruses in DNAs extracted from the le...
