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.

Polyostotic osteosarcoma associated with avian leukosis virus infection in a captive bare‐faced curassow (Crax fasciolata)

open access: yesBMC Veterinary Research, 2021
Background Osteosarcoma is a malignant mesenchymal bone tumor. Although it is a common tumor in the appendicular skeleton of dogs and cats, it is rarely reported in birds.

Genome-wide analysis reveals the extent of EAV-HP integration in domestic chicken [PDF]

open access: yes, 2015
Background: EAV-HP is an ancient retrovirus pre-dating Gallus speciation, which continues to circulate in modern chicken populations, and led to the emergence of avian leukosis virus subgroup J causing significant economic losses to the poultry industry.

Avian leukosis virus in indigenous chicken breeds, China [PDF]

open access: yesEmerging Microbes & Infections, 2015
Dear Editor, Avian leukosis viruses (ALVs) can induce various tumors and cause production problems.1 Besides being a cause of mortality in poultry,1 ALV can mutate much easier than other avian viruses.1,2,3 ALVs isolated from chickens are divided into six subgroups (A–J) on the basis of the differences in the envelope glycoproteins.1 More recently ...

Search for virus specific DNA sequences and viral particles in mitochondria of avian leukemic myeloblasts [PDF]

open access: yes, 1977
The intracellular localization of the avian myeloblastosis virus (AMV) genome was studied. Nuclear and mitochondrial DNAs from myeloblasts were examined by hybridization with 32P labeled AMV-RNA of high molecular weight for the presence of virus specific

Application of Immunohistochemistry to Study of Avian Leukosis Virus

open access: yesJournal of General Virology, 1972
Summary A modification of the peroxidase-labelled antibody technique was applied to study the distribution of virus antigens in chicken cells infected with two serotypes (A and B) of avian leukosis virus (ALV). Type-specific chicken antisera reacted only with cells infected with virus of the homologous envelope serotype. When unfixed cells were exposed

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.

A metagenomic comparison of endemic viruses from broiler chickens with runting stunting syndrome and from normal birds [PDF]

open access: yes, 2016
Runting-stunting syndrome (RSS) in broiler chickens is an enteric disease that causes significant economic losses to poultry producers worldwide due to elevated feed conversion ratios, decreased body weight during growth, and excessive culling.
