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

BMC 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.

Application of Immunohistochemistry to Study of Avian Leukosis Virus

Journal 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

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

Veterinary 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.

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

Emerging 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 ...

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 ...

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

Kafkas 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]

Infection 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 ...

Species-Specific Contribution of the Four C-Terminal Amino Acids of Influenza A Virus NS1 Protein to Virulence [PDF]

, 2010
Large-scale sequence analyses of influenza viruses revealed that nonstructural 1 (NS1) proteins from avian influenza viruses have a conserved C-terminal ESEV amino acid motif, while NS1 proteins from typical human influenza viruses have a C-terminal RSKV
