Virus-like particles in association with L strain cells.

Avian lymphoid leukosis: Virus-like particles in kidney Cells

Transient expression of virus-like particles in plants: a promising platform for rapid vaccine production

Transient expression is an efficient and fast system to express recombinant proteins which has been used in different eukaryotic hosts such as mammalian and plant cells. Several applications of this system have so far been used which expression of proteins of interest is one of them. Recently, plants have attracted attention for being used as hosts for the production of recombinant pharmaceutic...

An 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...

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...

Poliovirus Particles do not Form in Preinfected Cells with Reovirus

Background and Aims: Inhibition of viral growth in coinfected cells with two different viruses has been described. This phenomenon known as viral interference can occur in several virus host systems such as interference of enterovirus infection on poliovirus vaccine strains. In this study we superinfected reovirus infected HeLa cells with poliovirus to determine if poliovirus can replicate in s...
