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

Viruses, 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.

A recombinant avian leukosis virus subgroup j for directly monitoring viral infection and the selection of neutralizing antibodies. [PDF]

PLoS ONE, 2014
Avian leukosis virus subgroup J (ALV-J) has induced serious clinical outbreaks and has become a serious infectious disease of chickens in China. We describe here the creation of a recombinant ALV-J tagged with the enhanced green fluorescent protein ...

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

Biological 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 ...

Differential cytokine responses following Marek's disease virus infection in chicken genotypes differing in resistance to Marek's disease [PDF]

, 2003
The production of cytokine mRNAs, in addition to viral DNA, was quantified by real-time quantitative reverse transcription-PCR (RT-PCR) (cytokines) or PCR (virus) in splenocytes during the course of Marek's disease virus (MDV) infection in four inbred ...

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

Veterinary 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,

Intra- and interspecies transmission of H7N7 highly pathogenic avian influenza virus during the avian influenza epidemic in the Netherlands in 2003 [PDF]

, 2009
The poultry epidemic of H7N7 highly pathogenic avian influenza (HPAI) virus in the Netherlands in 2003 was probably the result of the introduction of an H7N7 low pathogenic avian influenza (LPAI) virus (by interspecies transmission from wild birds) and ...

Virus or Avian Myeloblastic Leukosis

Poultry Science, 1956
Abstract INTRODUCTION AVIAN leukosis is a complex of diseases which are not only of much economic importance, but which, in addition, comprise one category of virus-induced tumors. As a consequence, knowledge of the diseases is of fundamental interest in its bearing on the problem of cancer as a whole. Since the initial reports of the viral etiology
