Plaque formation of LaSota pathogenic strain of Newcastle disease virus adapted in chick embryo fibroblast cells
In order to adapt LaSota strain of Newcastle disease virus (NDV) on chick embryo fibroblast (CEF) cells, 0.1 ml from LaSota vaccine produced in Razi vaccine and serum research institute inoculated to the CEF cells and was passaged five times in the CEF grown in Eagle’s minimum essential medium (MEM). First to third passages were blind but in fourth passage cytopathic effect of virus was observe...
متن کاملAn electron microscope study of virus-like particles in chick embryo and L cell cultures.
Latent virus infections in chickens have been recognized for several years. Many investigators have seen spherical, virus-like particles in normal chicken cell cultures, and have suggested that they might have been the virus of avian lymphomatosis, which occurs frequently without producing disease symptoms and is transmitted trans-ovarially. Virus-like particles were also observed during the pr...
متن کاملI-19: Surrogate Egg Shell Culture for The Analysis of Avian Stem Cell Fate
Background: The chick embryo is a classical model to study embryonic development. However, most researchers have not studied the effect of embryonic manipulation on chick hatchability. To determine the effect of egg orientation and type of sealing film on the hatchability of cultured embryos, and to determine the fate of adulte stem cells injected into the blastoderm. Materials and Methods: Win...
متن کاملChemotherapy of virus infections.
In recent years, antibiotics have proved effective against many bacterial and all rickettsial infections of man, but are only of limited value in virus infections. The so-called broad spectrum antibiotics-aureomycin, terramycin and chloramphenicol-are effective against the viruses of the psittacosis-lymphogranuloma group and those causing primary atypical pneumonia. Many substances are therefor...
متن کاملStudies on Newcastle disease virus by the plaque method.
The establishment of a successful plaque method for counting infectious virus particles by Dulbecco (1952), with subsequent refinements by Dulbecco and Vogt (1953, 1954a), makes it possible to quantitatively assay animal viruses with a high degree of accuracy in a manner comparable to assays of bacterial viruses. Two methods of assay commonly used in characterizing any particular Newcastle dise...
