Avian leukosis in chickens: retrospective histopathology and antibody prevalence in some selected layer farms [PDF]

open access: yes, 2018
The aim of this study was retrospective histopathological on clinical samples and sero-prevalence of avian leukosis virus antibodies in layer farms were done. Histopathological samples (Liver) were preserved in 10% neutral buffered formalin and processed,

RNA‐centric world of retroviruses: unravelling the molecular strategies of genomic RNA packaging

open access: yesBiological Reviews, EarlyView.
ABSTRACT Retroviruses constitute a unique group of RNA viruses that have profoundly influenced both evolutionary trajectories and biomedical research. Their ability to reverse transcribe and integrate into host genomes has shaped genomic architecture across species and contributed to our understanding of oncogenes, gene regulation, and RNA biology ...

Knock-Out of Retrovirus Receptor Gene Tva in the Chicken Confers Resistance to Avian Leukosis Virus Subgroups A and K and Affects Cobalamin (Vitamin B12)-Dependent Level of Methylmalonic Acid

open access: yesViruses, 2021
The chicken Tva cell surface protein, a member of the low-density lipoprotein receptor family, has been identified as an entry receptor for avian leukosis virus of classic subgroup A and newly emerging subgroup K.

Suspected lymphoid leukosis visceral lymphoma with intestinal and ovarian involvement in a chicken

open access: yesVeterinary Record Case Reports, Volume 14, Issue 3, August 2026.
Abstract An adult hen from a small poultry flock was submitted for diagnostic investigation because of nonspecific clinical disease and suspected neoplasia. At necropsy, the bird had ascites, splenomegaly, severe intestinal adhesions, nodular intestinal lesions and ovarian masses. Histopathology revealed extensive infiltration of the intestinal mucosa,

Isolation of a second Avian leukosis group-specific antigen (gs-b) from avian myeloblastosis virus

open access: yes, 1970
Gs-b, a second group-specific antigenic protein of the avian leukosis group, has been isolated from Tween 80-ether treated avian myeloblastosis virus by Sephadex and carboxymethylcellulose chromatography, and compared by immunological and chemical means ...

Role of Virus-Encoded microRNAs in Avian Viral Diseases

open access: yesViruses, 2014
With total dependence on the host cell, several viruses have adopted strategies to modulate the host cellular environment, including the modulation of microRNA (miRNA) pathway through virus-encoded miRNAs.

Progress and Prospects of Rare Metal‐Based Electrochemiluminescence Sensors for Detection of Water Environmental Pollutants

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Water pollution is becoming increasingly severe, posing a serious hazard to human health and ecological security. Therefore, it is necessary to develop rapid, sensitive, and universal analytical methods to detect residual pollutants in actual water.

The DF-1 Chicken Fibroblast Cell Line: Transformation Induced by Diverse Oncogenes and Cell Death Resulting from Infection by Avian Leukosis Viruses [PDF]

open access: yes, 1998
DF-1 is a continuous cell line of chicken embryo fibroblasts. The cells are free of endogenous sequences related to avian sarcoma and leukosis viruses and have normal fibroblastic morphology.
