Establishment and Application of a Real-Time Recombinase Polymerase Amplification Assay for the Detection of Avian Leukosis Virus Subgroup J

Frontiers in Veterinary Science, 2022
Avian leukosis caused by avian leukosis virus (ALV), belonging to the genus Alpharetrovirus of the family Retroviridae, is associated with benign and malignant tumors in hemopoietic cells in poultry.

Tropism of subgroup J avian leukosis virus as detected byin situhybridization [PDF]

Avian Pathology, 1999
The HPRS-103 strain of avian retrovirus is the prototype of subgroup J avian leukosis virus (ALV-J) and causes myeloid leukosis in meat-type chickens. Using immunohistochemical detection of the viral groupspecific antigen (Gag) we have previously demonstrated that the induction of myeloid leukosis by ALV-J is associated with viral tropism for ...

Avian leukosis virus subgroup J infection alters viral composition in the chicken gut [PDF]

FEMS Microbiology Letters, 2020
ABSTRACT Chicken is one of the economically important poultry species. Avian leucosis virus subgroup J (ALV-J) has emerged as a serious cause of mortality and suboptimal performance of domestic chickens. Changes in virome may contribute to pathogenesis.

Co-infection with avian hepatitis E virus and avian leukosis virus subgroup J as the cause of an outbreak of hepatitis and liver hemorrhagic syndromes in a brown layer chicken flock in China

Poultry Science, 2020
Hens of a commercial Hy-line brown layer flock in China exhibited increased mortality and decreased egg production at 47 wk of age. From 47 to 57 wk, average weekly mortality increased from 0.11 to 3.0%, and egg production decreased from 10 to 30%, with ...

Baicalin is an inhibitor of subgroup J avian leukosis virus infection

Virus Research, 2018
Avian leukosis virus subgroup J (ALV-J) can cause great economic losses to the poultry industry worldwide. Baicalin, one of the flavonoids present in S.baicalensis Georgi, has been shown to have antiviral activities. To investigate whether baicalin has antiviral effects on the infection of ALV-J in DF-1 cells, the cells were treated with baicalin at ...

Chicken Glycogen Synthase Kinase 3β Suppresses Innate Immune Responses and Enhances Avian Leukosis Virus Replication in DF-1 Cells

Microbiology Spectrum, 2023
Glycogen synthase kinase 3β (GSK3β) is a widely distributed multifunctional serine/threonine kinase. In mammals, GSK3β regulates important life activities such as proinflammatory response, anti-inflammatory response, immunity, and cancer development ...

Molecular Epidemiology of Avian Leukosis Virus Subgroup J in Layer Flocks in China [PDF]

Journal of Clinical Microbiology, 2012
ABSTRACT Avian leukosis virus subgroup J (ALV-J) was first isolated from meat-type chickens in 1988. No field cases of ALV-J infection or tumors in layer chickens were observed worldwide until 2004. However, layer flocks in China have experienced outbreaks of this virus in recent years. The molecular epidemiology of ALV-J strains

Avian leukosis virus subgroup J associated with the outbreak of erythroblastosis in chickens in China [PDF]

Virology Journal, 2013
Abstract Background Emaciation, depression and lethargy were observed in two flocks of Chinese local breed and one flock of commercial layer chicken infected naturally from 2010 to 2011. The aims of this study were to diagnose.

A glance over the fence: Using phylogeny and species comparison for a better understanding of antigen recognition by human γδ T‐cells

Immunological Reviews, Volume 298, Issue 1, Page 218-236, November 2020., 2020
Abstract Both, jawless and jawed vertebrates possess three lymphocyte lineages defined by highly diverse antigen receptors: Two T‐cell‐ and one B‐cell‐like lineage. In both phylogenetic groups, the theoretically possible number of individual antigen receptor specificities can even outnumber that of lymphocytes of a whole organism.

Evolutionary trajectory of fish Piscine novirhabdovirus (=Viral Hemorrhagic Septicemia Virus) across its Laurentian Great Lakes history: Spatial and temporal diversification

Ecology and Evolution, Volume 10, Issue 18, Page 9740-9775, September 2020., 2020
This study analyses the evolutionary trajectory of a novel virus over its 17‐year history, examining the dynamics of its host relationships and its patterns across geographic space and evolutionary time. We sequence its entire genome and discern that the virus has significantly changed, with its original genotypes disappearing and being replaced in a ...
