Avian leukosis embraces several different leukaemia-like neoplastic diseases of the haematopoietic system. These tumours are induced by avian leukosis virus (ALV), members of the Alpharetrovirus genus of the family Retroviridae (Regenmortel et al., 2000).

Avian leukosis refers to several leukaemia-like proliferative diseases caused by the avian leukosis virus (ALV). ALVs consist of 10 subgroups designated A to J. 6 of the 10 affect chickens. Subgroups A and B are the most common, especially in egg laying hens, followed by subgroup J which occurs in broilers and egg laying hens.

Avian leukosis is a neoplastic disease of poultry characterized by tumors of hemopoietic tissues and sarcomas, including lymphoid leukosis, myeloid leukosis, and erythroid leukosis, induced by a related group of avian leukosis/sarcoma viruses. Disease usually …

禽白血病（Avian leukosis）是由禽C型反录病毒群的病毒引起的禽类多种肿瘤性疾病的统称，三类传染病。 主要是淋巴细胞性白血病，其次是成红细胞性白血病、成髓细胞性白血病。

摘要 从禽白血病的病原学、病毒基因组及蛋白结构、流行病学、临床症状与病理变化、诊断及防控等方面对禽白血病的研究现状进行了综述,针对防控存在的问题对将来的研究方向提出了展望。

2024年4月10日 · Avian leukosis virus Subgroup-J (ALV-J) is a rapidly oncogenic evolving retrovirus infecting a variety of avian species; causing severe economic losses to the local poultry industry. To investigate ALV-J, a total of 117 blood samples and 57 tissue specimens of different organs were collected for virological, and pathological identification ...

Infection by exogenous avian leukosis viruses (ALVs) causes economic loss from neoplastic mortality and from impaired performance of subclinically infected chickens. This paper reviews progress in research related to natural infection and its control.

禽白血病病毒[avian leukemia (leukosis) virus，ALV]隶属反转录病毒科、α反转录病毒属成员，其基因组为单股、正链、线性RNA的二聚体，具有经典的C型反转录病毒基因组结构(5′LTR-5′UTR-gag-pol-env-3′UTR-3′LTR)，可引起禽类的多种肿瘤性疾病 。

2019年2月28日 · Avian leukemia viruses (ALVs) are members of retrovirus family and have been classified into 11 subgroups 1, 2, 3. Subgroup A of ALV (ALV-A) is an exogenous ALV that can cause viremia,...

2025年3月1日 · Avian leukosis virus (ALV) induces various tumors and immunosuppression, endangering the poultry industry. However, the prevalence of ALV infection among indigenous chickens in Yunnan Province remains unclear. In this study, we aimed to investigate the presence of ALV in these breeds.
