Isolation of Subgroup J Avian Leukosis Virus in Korea

Journal of Veterinary Science, 2002
Two subgroup J avian leukosis viruses (ALVs) were isolated from broiler breeder flocks, in which myeloid leukosis had occurred. The isolates could be classified as subgroup J ALV by the positive reaction in polymerase chain reaction (PCR) with primers specific for subgroup J ALV. Two isolates replicated in chicken embryo fibroblast (CEF) cells from the

Retroviral Infections Affect Survival and Clutch Size of Female Wild Turkeys

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We investigated the effects of two oncogenic retroviruses, lymphoproliferative disease virus (LPDV) and reticuloendotheliosis virus (REV), on survival and reproduction of wild turkeys in Maine. REV infection reduced female annual survival by nearly half, while LPDV‐infected hens laid fewer eggs, though other reproductive metrics were unaffected.

A 19-nucleotide insertion in the leader sequence of avian leukosis virus subgroup J contributes to its replication in vitro but is not related to its pathogenicity in vivo. [PDF]

PLoS ONE, 2014
Subgroup J avian leukosis virus (ALV-J) was first isolated from meat-type chickens that had developed myeloid leukosis and since 2008, ALV-J infections in chickens have become widespread in China.

Protease‐mediated maturation of M‐PMV reverse transcriptase into a functional heterodimer

Protein Science, Volume 35, Issue 2, February 2026.
Abstract Reverse transcriptase (RT) of retroviruses orchestrates viral replication, yet its structural diversity remains poorly understood. Well‐studied RTs, such as those from HIV‐1, murine leukemia virus, and avian myeloblastosis virus, were characterized decades ago, but less prominent retroviruses have escaped detailed analysis.

Chicken Infectious Anemia Virus Markedly Enhances the Pathogenicity of Infectious Bronchitis Virus–Infected Chickens

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Chicken infectious anemia virus (CIAV) and infectious bronchitis virus (IBV) represent two of the most economically significant pathogens in the global poultry production. In recent years, coinfections involving CIAV and IBV have become increasingly prevalent in clinical scenarios across Southern China and globally.

Pathological mechanisms of avian viral oncogenesis: The central role of MicroRNA

Poultry Science
Avian oncogenic viruses represent a major cause of neoplastic and immunosuppressive diseases in poultry, leading to substantial economic losses worldwide and providing valuable models for studying virus-induced tumorigenesis. Among these viruses, Marek’s

The passage of cells can improve the detection rate of avian leukosis virus to facilitate the elimination of avian leukosis in chickens [PDF]

SpringerPlus, 2013
Abstract Avian leukosis (AL) is one of the most harmful diseases to the poultry industry in China. The detection of the avian leukosis virus (ALV) p27 antigen plays a decisive role in the elimination of avian leukosis. To explore the influence of passaging cells on the detection rate of the ALV p27 antigen, 21 aseptic anticoagulated blood ...

Epidemiology of Marek’s Disease Virus Type 2 and the Molecular and Pathology Characterization of Virus Isolates in China (2015–2024)

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Marek’s disease (MD) continues to cause significant economic losses in the global poultry industry. During routine MD surveillance in China, MD virus type 2 (MDV‐2), which has the potential for widespread dissemination, was detected. In this study, 2842 suspected MD samples were collected from 237 poultry flocks vaccinated against MD across 21 ...
