Immunogenicity and safety of Queensland V4 and Ulster 2C strains of Newcastle disease virus given to maternally immune, newly hatched chickens by nebulization.

The response of ducks to V4 Newcastle disease virus and its transmission to contact ducks and domestic chickens

Experimental infection of Muscovy ducks with V4 strain of Newcastle disease virus was undertaken to determine the response of the ducks to the virus and the possibility of virus transmission to ducks and chickens in village like conditions. Twelve ducks were randomly and equally divided into three groups of control, inoculated and in-contact. Additionally, the chickens were placed into two grou...

Molecular Detection of Lentogenic Strain of Newcastle Disease Virus in Commercial Broiler Chickens Using Sentinel Birds in Iran: The First Report

Abstract Background and Aims: Newcastle disease (ND) is a highly contagious disease that affects many species of birds and causes significant economic losses to the poultry industry worldwide and the pathogenicity of Newcastle disease virus (NDV) strains varies with different virulence. We aim to detect lentogenic (low virulence) ND virus (ND/IR 2010) using sentinel birds and molecular det...

Immune response of chickens to four lentogenic strains of Newcastle disease virus propagated in lamb kidney cell cultures

Immunogenicity of commercial, formaldehyde and binary ethylenimine inactivated Newcastle disease virus vaccines in specific pathogen free chickens

Newcastle disease (ND) is one of the most important diseases that affect birds; the epizootic nature of the disease has caused severe economic losses in the poultry industry worldwide. In this experiment ND virus (NDV) was inactivated by two different chemicals binary ethylenimine (BEI) and formaldehyde. Formaldehyde was used at 0.1%, while BEI was used at concentrations of 1 to 4 mM. NDV inact...

Effect of in ovo Injection of Royal Jelly on Post-Hatch Growth Performance and Immune Response in Broiler Chickens Challenged with Newcastle Disease Virus

The aim of this experiment was to study the effect of in ovoinjection of royal jelly (RJ) on growth performance and immune response in broiler chickens challenged with Newcastle disease virus. A total of 200 hatching eggs were divided into four groups of 50 eggs each one using a completely randomized design. The eggs were injected with sterilized sodium bicarbonate buffer (pH=10.4) or RJ (88%) ...
