Occurrence of avian leukosis virus subgroup J in commercial layer flocks in China

Avian Pathology, 2004
Mortality from myeloid leukosis was observed in commercial layers from 12 farms in northern China. Affected chickens were extremely thin and dehydrated, bleeding occurred in feather follicles and claws, combs were pale and anaemic, phalanges were swollen, and many yellowish-white tumours were seen on the visceral surface of the sternum.

Differential expression of microRNAs in avian leukosis virus subgroup J-induced tumors

Veterinary Microbiology, 2013
Avian leukosis virus subgroup J (ALV-J) has become pandemic and induced serious clinical outbreaks in chickens in China. In particular, ALV-J induced various clinical tumors in infected chickens, which caused enormous economic losses to poultry.

Anti-CD81 antibody blocks vertical transmission of avian leukosis virus subgroup J

Veterinary Microbiology, 2022
Control of ALV-J in breed of chicken is still a serious issue that need more attention to be paid. Vertical transmission of ALV-J often give rise to more adverse pathogenicity. However, the way to elimination of ALV-J underlying vertical transmission remains not-well understood.

High Virus Titer in Feather Pulp of Chickens Infected with Subgroup J Avian Leukosis Virus

Avian Diseases, 2002
Subgroup J avian leukosis viruses (ALVs), which are a recombinant virus between exogenous and endogenous ALVs, can spread by either vertical or horizontal transmission. Exogenous and endogenous ALVs can be detected in feather pulp. In this study, virus titers in feather pulp of chickens infected with subgroup J ALV were compared with those of plasma ...

Genetic mutations of avian leukosis virus subgroup J strains extended their host range

Journal of General Virology, 2014
The genetic diversity of avian leukosis virus subgroup J (ALV-J) is determined not only by the env gene, but also by its 3′ UTR and 3′ LTR. They all play important roles in extending the host range and tumour development. In the present study, one ALV-J strain (ZB110604-6) from Black-Bone Silky Fowl (BSF) and three ALV-J strains (ZB110604-3/4/5) from ...

Geese not susceptible to virulent subgroup J avian leukosis virus isolated from chickens

Avian Pathology, 2019
To determine whether geese are susceptible to infection by avian leukosis virus (ALV), 702 serum samples from domestic and foreign goose breeds were screened for p27 antigen as well as being inoculated into DF-1 cell cultures to isolate ALV. Although 5.7% of samples were positive for p27 antigen, reactivity appeared to be non-specific because no ALV ...

[Cross-species Transmission of Avian Leukosis Virus Subgroup J].

Bing du xue bao = Chinese journal of virology, 2016
Avian leukosis virus subgroup J (ALV-J) is an avian retrovirus that can induce myelocytomas. A high-frequency mutation in gene envelope endows ALV-J with the potential for cross-species transmission. We wished to ascertain if the ALV-J can spread across species under selection pressure in susceptible and resistant hosts.

Avian leukosis virus subgroup J: a rapidly evolving group of oncogenic retroviruses

Research in Veterinary Science, 1999
A strain of avian leukosis virus (ALV) belonging to a new envelope subgroup J was isolated in the UK in 1988 from meat-type chickens. The disease caused by the members of this subgroup has since spread very rapidly worldwide and has become one of the major problems facing the broiler meat industry.

Detection of subgroup J avian leukosis virus infection in Australian meat‐type chickens

Australian Veterinary Journal, 2004
Objective To determine the extent of avian leukosis virus subgroup J (ALV‐J) infection in Australian broiler breeder flocks, using virus isolation and molecular biological detection. Any resultant ALV‐J viral isolates to be characterised by neutralisation cross testing in order to determine antigenic relationships to overseas isolates of ALV‐J.

Efficacy of an autophagy-targeted DNA vaccine against avian leukosis virus subgroup J

Vaccine, 2017
Infection with the avian leukosis virus subgroup J (ALV-J) can lead to neoplastic disease in chickens, inflicting significant economic losses to the poultry industry. Recent reports have identified inhibitory effects of ALV-J on autophagy, a process involving in innate and adaptive immunity.
