newcastle disease is one of the most important causes of economic losses in the poultry production and can be resulted in high mortality. antibody detection is also an important tool for assessment of the immunity against the disease. in the present study a trial was conducted to evaluate the effect of an immune stimulator (echinacea purpurea) on antibody production against newcastle disease va...

Newcastle disease is characterized by respiratory manifestations in association with nervous and/or digestive symptoms. Its prevention is done by vaccination with live attenuated (lentogenic strains) and/or killed vaccines. The lentogenic strains can lead to strong post-vaccination reaction, principally due to the presence of other pathogenic agents. Among them, Mycoplasma synoviae is worldwide...

We report here the complete genome sequence of a Newcastle disease virus (NDV) isolated from a wild peacock. Phylogenetic analysis showed that it belongs to genotype II, class II of NDV strains. This study helps to understand the ecology of NDV strains circulating in a wild avian host of this geographical region during the outbreak of 2012 in northwest India.

In this study, the complete genome sequence of the heat-resistant Newcastle disease virus (NDV) strain HR09, which was isolated in China in the 1990s, was determined and characterized phylogenetically. This is the first report regarding the complete genomic information of a thermostable NDV strain from China.

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.

background & aim: the recent study was conducted to investigate the effects of thyme extract in drinking water on immune response of broiler chickens. experimental:  a total of 245 day-old broiler chicks were purchased and 20 chicks were bled for determination maternal antibody and remaining chicks divided into 5 equal groups. chickens of group a, b and c received 0.1%, 0.15% and 0.2% ofthy...

The MET95 strain of a lentogenic Newcastle disease virus (NDV) isolated from a broiler in Japan, showed unique hemagglutination (HA) activity. The MET95 strain failed to show HA when examined by rapid glass plate method although they showed HA titer of 1:1,024 by micro-plate method. This unique HA was also observed after the MET95 strain was passaged ten times in chickens. The failure of HA by ...

Goose/GD/2010 is a newly emerging Newcastle disease virus (NDV) isolated from a sick goose flock in southern China. Here, we report the complete genome sequence of this isolate, which belongs to NDV subgenotype VIIb. This is the first report about the complete genome information of an isolate of subgenotype VIIb in China.

Here, the whole genome sequences of two Newcastle disease viruses (NDV) of genotype VIII, which were isolated from west China in the 1980s, were determined and characterized phylogenetically. This is the first report with respect to the complete genomic information of genotype VIII NDV strains.
