Plaque assay of avian sarcoma viruses using casein.
The caseinolytic activity of several strains of Rous sarcoma virus (RSV), conditional and nonconditional mutants of RSV, and nontransforming avian leukosis viruses was investigated. Only those viruses capable of transforming chick fibroblasts in vitro induced lysis of casein incorporated into an agar overlay. Lysis produced distinct clear areas in the turbid casein-agar gel which allowed a quan...
متن کاملMetastatic 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...
متن کاملComparison of the small RNAs of polymerase-deficient and polymerase-positive Rous sarcoma virus and another species of avian retrovirus.
The small RNAs contained in virions of avian leukosis and sarcoma viruses are a virus-specific subset of the total small RNA population of the host cell. The reverse transcriptase protein must be present in the budding virion for this selection to take place. Virions of the alpha form of the Bryan strain of Rous sarcoma virus, which lack detectable reverse transcriptase, incorporated an unselec...
متن کاملReticuloendotheliosis Viruses, and Chicken Cells
Antibodies against a large and a small DNA polymerase isolated from chicken embryos and against avian myeloblastosis virus DNA polymerase were used to study the serological relationships of the DNA polymerase activities of three avian systems with RNA and a DNA polymerase-avian leukosis-sarcoma viruses, reticuloendotheliosis viruses, and a fraction from uninfected chicken cells. The DNA polymer...
متن کاملTUMOR VIRUS RNAs AND TUMOR VIRUS GENES
The RNAs of several classes of avian and murine RNA tumor viruses were compared. The 60-70s RNA complex of cloned nondefective avian sarcomaviruses contains only 30-40s RNA species of class a, which are larger than the 30-40s RNA species of class b found in avian transformation-defective or leukosis viruses. The RNA of a recombinant avian sarcoma virus, carrying a host range marker of a leukosi...
