Association of Chicken Mx1 Polymorphisms with Susceptibility in Chicken Embryos Challenged with Virulent Newcastle Disease Virus

Efficacy of Thermostable Newcastle Disease Virus Strain I-2 in Broiler Chickens Challenged with Highly Virulent Newcastle Virus

Newcastle disease (ND) is a major threat to poultry industry production throughout developing countries. The Newcastle disease viruses (NDVs) infecting industrialized and indigenous poultry in Iran are velogenic strains and responsible for the frequent outbreaks of ND in poultry farms even in vaccinated flocks causing serious economic losses in the commercial and indigenous poultry. However, va...

Detection of Newcastle Disease Virus in Infected Chicken Embryos and Chicken Tissues by Rt-pcr

RT-PCR for the detection of Newcastle disease virus (NDV) in allantoic fluids of SPF embryonated eggs as well as in tissues of SPF chickens infected experimentally is described. The method proved to be specific as all tested NDVs were detected and no cross reaction with other RNA viruses was observed. Sensitivity of the method was established at 10ELD50/0.1 ml. To detect NDV in chicken tissues,...

Infectious Bronchitis virus interference with Growth of Newcastles disease virus. 1 - Study of interference in chicken embryos

Associations of chicken Mx1 polymorphism with antiviral responses in avian influenza virus infected embryos and broilers.

Avian influenza virus (AIV) is a major respiratory disease of poultry that causes catastrophic losses to the poultry industry. The Mx protein has been shown to confer antiviral responses to influenza viruses in mice. One nonsynonymous substitution (S631N) in the chicken Mx protein is reported to be associated with resistance to AIV infection in vitro. The previous studies suggested controversy ...

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...
