Mucosal surface provide portal entry for a majority of infectious agents. Hence, protection at the mucosal surface through immunization plays an important role in containing its systemic spread. Mucosal vaccination of chicken at early stages of life with live attenuated strain of Newcastle disease virus (NDV) induces both cellular and humoral immune responses against the Newcastle disease. In o...

The first complete genome sequence of a strain of Newcastle disease virus (NDV) from genotype XIV is reported here. Strain duck/Nigeria/NG-695/KG.LOM.11-16/2009 was isolated from an apparently healthy domestic duck from a live bird market in Kogi State, Nigeria, in 2009. This strain is classified as a member of subgenotype XIVb of class II.

The importance of the fourth variable (V4) region of the human immunodeficiency virus 1 (HIV-1) envelope glycoprotein (Env) in virus infection has not been well clarified, though the polymorphism of this region has been found to be associated with disease progression to acquired immunodeficiency syndrome (AIDS). In the present work, we focused on the correlation between HIV-1 gp120 V4 region po...

Newcastle Disease (ND) is a major viral disease in Indonesia. It is an RNA virus belongs to Paramyxovirinae. It is well known that RNA virus is easily to mutate. In some cases, this mutation could generate virulence alteration. It is noted that mutation of NDV which has avirulent amino acid sequence on the cleavage site, could mutate to be virulent Newcastle Disease Virus (NDV). It is needed to...

The first complete genome sequence of an African-origin Newcastle disease virus belonging to genotype XIII is described here. The virulent strain chicken/Zambia/Chiwoko/2015 was isolated from diseased chickens in 2015.

We report here the complete genome sequence of a Newcastle disease virus isolate, NDV/Yakutiya/mallard/852/2011, isolated from a mallard in Russia. On the basis of phylogenetic analysis, this strain was clustered into class II genotype Ib.

Highly pathogenic avian influenza H5N1 and Newcastle disease viral infections cause severe illness in chickens and vaccination is a strategic tool of controlling these diseases. Hence, this study was conducted to evaluate the efficacy of using both recombinant herpesvirus of turkey (rHVT-H5 and rHVT-F) vector vaccines at day-old, in the hatchery, under field conditions. Vaccinated chickens were...

background and aims: newcastle disease virus (ndv) is one of the major pathogen in poultry. vaccination is intended to control the disease as an effective solution nevertheless this virus is a growing threat to the poultry industry. f gene open reading frame (orf) from ndv is 1650 bp, encoding a protein of 553 amino acids that can induce protective immunity alone. the f glycoprotein on the surf...

background: newcastle disease virus (ndv) is the causativeagent of the newcastle disease (nd), a highly contagiousdisease in birds that causes significant economic losses to thepoultry industry worldwide. nd is endemic in iran and outbreaksare reported regularly in commercial poultry flocks and differentspecies of birds. objectives:the current study was carried outto characterize ndv based on p...

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...
