Effect of low dose gamma-radiation upon Newcastle disease virus antibody level in chicken

Background: The specific antibody response against Newcastle disease virus (NDV) in the blood serum of chickens hatched from eggs exposed to low dose gamma-radiation was studied. Materials and methods: Two groups of eggs of commercial meat chicken lines were irradiated with the dose of 0.30 Gy 60Co gamma-rays before incubation and on the 19th day of incubation, respectively. The same num...

The Tween 80 Toxicity in Chicken Embryos and Effect on the Kinetics of Newcastle Disease Virus Replication

Background: Non-ionic surfactant, Tween-80 (TW80) is commonly used for drug delivery due to its effect on the cell membrane permeation. The change in permeability can also increase viral infectivity in cells. This study was undertaken to improve upon Newcastle disease virus (NDV) titer cultivated with embryonic chicken eggs. Methods: The toxicity of TW80 was investigated against chicken embryo...

Effects of Chicken Interferon Gamma on Newcastle Disease Virus Vaccine Immunogenicity

More effective vaccines are needed to control avian diseases. The use of chicken interferon gamma (chIFNγ) during vaccination is a potentially important but controversial approach that may improve the immune response to antigens. In the present study, three different systems to co-deliver chIFNγ with Newcastle disease virus (NDV) antigens were evaluated for their ability to enhance the avian im...

Tumorcidal Effect of Recombinant Newcastle Disease Virus

We have generated GFP expressing recombinant Newcastle Disease Virus (rNDV-GFP) based on a live vaccine strain which contains a less pathogenic cleavage site of F protein leading to restricted viral growth in vivo. We evaluated the rNDV have an effect of oncolytic activity to B16 melanoma cell. The rNDV-GFP infected efficiency to B16 cells and induced cell death. Apoptosis-related genes, Bax an...
