Identification of a cellular receptor for subgroup E avian leukosis virus.

Serologic profile of avian leukosis virus subgroup-J, Mycoplasma gallisepticum and Mycoplasma synoviae in broiler grandparent flocks of Iran.

  Avian Leukosis Virus Subgroup-J (ALV-J). Mycoplasma gallisepticum (MG) and MycopJasma synviae (MS) are important pathogens in chickens that cause severe economical losses in poultry industry throughout the world. Seven broiler grandparent flocks of Iran (six broiler strains) were sampled randomly at the ages of 8-63 wk (100 samples from each flock) for antibody detection to ALV-J, MG, and MS ...

Metastatic cutaneous neuro- myofibroblastic sarcoma induced by avian leukosis virus subgroup J in a rooster (Gallus gallus domesticus)

An adult native cock (Gallus gallus domesticus) referred to the aviary clinic with multiple different sizes of round dermal nodules. The bird died few days later, and was then submitted for further evaluation. Macroscopic and microscopic examinations as well as a PCR test were done to identify type and cause of the tumor. In histopathological assessment of biopsy specimen, it consisted of inter...

Detection of avian leukosis virus subgroup J in albumen of commercial and native fowl eggs using RT-PCR in Fars province of Iran

The subgroup J of ALV (ALV-J) has emerged as an important pathogen of meat-type chickens since1989. This virus is responsible for economic losses due to both mortality and depressed performance inchickens. So, the objective of this study is the detection of ALV-J in the albumen of commercial and nativefowl eggs using RT-PCR. Three hundred and seventy egg albumens were randomly selected from dif...

TVB receptors for cytopathic and noncytopathic subgroups of avian leukosis viruses are functional death receptors.

The identification of TVB(S3), a cellular receptor for the cytopathic subgroups B and D of avian leukosis virus (ALV-B and ALV-D), as a tumor necrosis factor receptor-related death receptor with a cytoplasmic death domain, provides a compelling argument that viral Env-receptor interactions are linked to cell death (4). However, other TVB proteins have been described that appear to have similar ...

Identification and characterization of the viral interaction determinant of the subgroup A avian leukosis virus receptor.

The cellular receptor for subgroup A avian leukosis viruses (ALV-A) has a small, 83-amino-acid extracellular domain containing a motif that is related in sequence to the ligand binding repeats of the low-density lipoprotein receptor. Extensive mutagenesis of the ALV-A receptor has identified two acidic amino acids (Asp-46 and Glu-47) and an adjacent aromatic amino acid (Trp-48) in the carboxy-t...
