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

open access: yesPoultry 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 ...

A PRELIMINARY REPORT OF SUBGROUP J AVIAN LEUKOSIS VIRUS-INFECTION IN IMPORTED BROILER PARENT CHICKENS [PDF]

open access: yesVeterinary Medical Journal - Giza, 1999
Three imported broiler parent farms suffering from high incidence of tumor mortality were investigated. Gross pathological lesions were suggestive of the novel subgroup J of avian leukosis virus (ALV) infection.

Determination of the tumor virus b locus in turkish native chicken breeds [PDF]

open access: yesKafkas Universitesi Veteriner Fakültesi Dergisi, 2017
Avian leukosis viruses (ALV) are retroviruses that can induce tumors in chicken. Typically, ALV is controlled through husbandry. However, genetic improvement and/or, selective breeding techniques, offer the unique possibility of true resistance.

Analysis of avian leukosis virus infections with an enzyme immunoassay [PDF]

open access: yesInfection and Immunity, 1981
An enzyme-linked immunosorbent assay (ELISA) for avian leukosis virus group-specific antigen was used to study infections with and shedding of avian leukosis virus in a commercial flock of chickens with a known high incidence of infection. Avian leukosis virus group-specific antigen was detected in serum or cloacal washings from 76% of a group of 100 ...

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 ...

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

open access: yesPLoS 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 ...

Virus or Avian Myeloblastic Leukosis

open access: yesPoultry 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
