The immunological relationship between filtrable agent, Salmonella and murine leukosis [PDF]

open access: yes, 1977
Salmonella typhimurium was invariably isolated from our J strain murine leukosis. Immunization of D103 mice with either inactivated Salmonella typhimurium or the cell-free extract of leukosis inhibited the transplantation of leukosis.

Truncation of the NS1 protein converts a low pathogenic avian influenza virus into a strong interferon inducer in duck cells [PDF]

open access: yes, 2010
The NS1 protein of influenza A viruses is known as a nonessential virulence factor inhibiting type I interferon (IFN) production in mammals and in chicken cells. Whether NS1 inhibits the induction of type I IFNs in duck cells is currently unknown.

MOLECULAR CHARACTERIZATION AND HISTOPATHOLOGICAL ANALYSIS OF AVIAN RETICULOENDOTHELIOSIS VIRUS FROM GUINEA FOWL IN TAMIL NADU [PDF]

open access: yesExploratory Animal and Medical Research
The present study was carried out to detect the causative agent of sudden death in guinea fowl f lock maintained at organized poultry farm, Orathanadu. On post mortem examination, liver was enlarged and revealed multiple grayish areas.

Differential contribution of PB1-F2 to the virulence of highly pathogenic H5N1 influenza A virus in mammalian and avian species [PDF]

open access: yes, 2011
Highly pathogenic avian influenza A viruses (HPAIV) of the H5N1 subtype occasionally transmit from birds to humans and can cause severe systemic infections in both hosts.

Ubiquitin in avian leukosis virus particles

open access: yesVirology, 1990
We have identified unconjugated ubiquitin as a component of avian leukosis virus (ALV). Quantitation both by immunoblotting and by protein staining showed that ubiquitin makes up about 0.5% of total viral protein, corresponding to 100 molecules per virion. This level is about fivefold higher than the level of unconjugated ubiquitin in the cytosol, when

Antigenic drift in H5N1 avian influenza virus in poultry is driven by mutations in major antigenic sites of the hemagglutinin molecule analogous to those for human influenza virus [PDF]

open access: yes, 2011
H5N1 highly pathogenic avian influenza virus has been endemic in poultry in Egypt since 2008, notwithstanding the implementation of mass vaccination and culling of infected birds.

Effects of chicken anaemia virus on experimental leukosis, induced by avian myelocytomatosis virus Mc29

open access: yesBulgarian Journal of Veterinary Medicine, 2021
The effects of concomitant infection with chicken anaemia virus (CAV) on the incidence, clinical manifestation and mortality from leukosis, induced by the avian myelocytomatosis virus strain Mc29 were studied.

PATHOLOGICAL AND MOLECULAR STUDIES ON AVIAN LEUKOSIS VIRUS SUBGROUP (J) IN CHICKEN PARENTS FLOCKS [PDF]

open access: yesVeterinary Medical Journal - Giza, 2006
Tee present study was carried out on 10 parent chickens flocks collected from different provinces. The examined cases were classified into 47 commercial layers and 198 broiler parents to study the gross and microscopical lesions of different tumors ...

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.
