Molecular Detection and Genetic Characterization of Avian Leukosis Virus From Field Outbreaks in Bangladesh [PDF]

Veterinary Medicine and Science, Volume 10, Issue 6, November 2024.
Histopathological examination of the liver from an avian leukosis virus (ALV)‐infected chicken reveals tissue alterations. Molecular detection confirms the presence of ALV in the liver samples. Evolutionary origin analysis traces the identified ALV strain. Mutational analysis and structural examination of the ALV envelope (Env) protein provide insights

MiR-125b Suppression Inhibits Apoptosis and Negatively Regulates Sema4D in Avian Leukosis Virus-Transformed Cells

Viruses, 2019
Subgroup J avian leukosis virus (ALV-J), an oncogenic retrovirus, causes hemangiomas and myeloid tumors in chickens. We previously showed that miR-125b is down-regulated in ALV-J-induced tumors.

Detection and genetic diversity of subgroup K avian leukosis virus in local chicken breeds in Jiangxi from 2021 to 2023. [PDF]

Front Microbiol
Avian leukosis virus subgroup K (ALV-K) is a new subgroup of avian leukosis virus (ALV) that was first identified in Chinese native chickens in recent years. To further understand the molecular epidemiology and evolutionary diversity of ALV-K, this study

Characterization of subgroup J avian Leukosis virus isolated from Chinese indigenous chickens

Virology Journal, 2018
Background In spite of the purification of the laying hens and broilers of avian leukosis virus (ALV) has made remarkable achievements, the infection of ALV was still serious in Chinese indigenous chickens.

Gp85 protein encapsulated by alginate-chitosan composite microspheres induced strong immunogenicity against avian leukosis virus in chicken [PDF]

Front Vet Sci
IntroductionAvian leukosis, a viral disease affecting birds such as chickens, presents significant challenges in poultry farming due to tumor formation, decreased egg production, and increased mortality. Despite the absence of a commercial vaccine, avian

Vertical transmission of avian leukosis virus subgroup J (ALV-J) from hens infected through artificial insemination with ALV-J infected semen

BMC Veterinary Research, 2017
Background Avian leukosis virus (ALV) is one of the main causes of tumour development within the poultry industry in China. The subgroup J avian leukosis viruses (ALV-J), which induce erythroblastosis and myelocytomatosis, have the greatest pathogenicity

Chicken hepatomegaly and splenomegaly associated with novel subgroup J avian leukosis virus infection

BMC Veterinary Research, 2022
Background Subgroup J avian leukosis virus (ALV-J) is an oncovirus which can induce multiple types of tumors in chicken. In this report, we found novel ALV-J infection is closely associated with serious hepatomegaly and splenomegaly in chicken.
