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

Frontiers in Microbiology
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

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 ...

[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.

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 ...

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. Molecular characterisation of HPRS -103, the prototype

Outbreak of myelocytomatosis caused by mutational avian leukosis virus subgroup J in China, 2018

Transboundary and Emerging Diseases, 2018
Avian leukosis virus subgroup J (ALV-J) was isolated in meat-type breeder chickens for the first time in 1988 in the United Kingdom. Due to the application of an eradication program, there were fewer reports related to myelocytomatosis or ALV-J in China after 2013.

Polymerase Chain Reaction for Detection of Avian Leukosis Virus Subgroup J in Feather Pulp

Avian Diseases, 2002
Feather pulp from experimentally infected chickens was used as a source of DNA for polymerase chain reaction (PCR) amplification of avian leukosis virus subgroup J (ALV-J) proviral DNA. A primer set that produces a large amplicon (approximately 2,125) was used to detect ALV-J proviral DNA.

[Research progress in avian leukosis virus subgroup J in China].

Sheng wu gong cheng xue bao = Chinese journal of biotechnology
Avian leukosis is a major neoplastic disease caused by avian leukosis viruses (ALVs), which are classified into 11 subgroups (ALV-A to ALV-K). Among them, ALV subgroup J (ALV-J) has undergone significant epidemiological changes since its introduction into China in 1999. It initially transmitted among broilers and then rapidly spread to commercial layer

[Cloning and expression of gp37 gene of avian leukosis virus subgroup J].

Bing du xue bao = Chinese journal of virology, 2012
The transmembrane protein (TM) encoded by gp37 gene plays a critical role when virus fusion with cell membrane occurs. Several highly conserved regions in TM are important targets for antivirus studies. Studies on structure and function of TM will provide basic information for anti-retrovirus, especially for avian leukosis virus.
