Background: Newcastle disease virus (NDV) is a dangerous viral disease, infecting a broad range of birds, and has a fatal effect on the poultry industries. The attachment and consequently fusion of the virus to the host cell membrane is directed by the two superficial glycoproteins, the hemagglutinin-neuraminidase (HN) and the fusion (F) which is considered as the important tar...
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...

background: newcastle disease is one of the most serious viral diseases in the poultry worldwide. objectives: since the traditional strategies have been hardly effective in controlling the disease, the purpose of this study was to introduce new methods for early and rapid diagnosis of newcastle. the present study helps to reduce further damage to the poultry industry. methods: rna extraction wa...
Five strains of Newcastle disease virus (NDV) were obtained from poultry in Vojvodina, Serbia during the outbreaks in 2006 and 2007. These isolates were confirmed and genotypically characterized by reverse transcription polymerase chain reaction (RT-PCR) with primer specific to the viral fusion (F) protein (572bp), and by sequencing of partial F gene for phylogenetic analysis. Phylogenetic anal...
The purpose of this paper is to investigate the correlation between meteorological factors and Newcastle disease incidence, and to determine the key factors that affect Newcastle disease. Having built BP neural network forecasting model by Matlab 7.0 software, we tested the performance of the model according to the coefficient of determination (R2) and absolute values of the difference between ...
Counterimmunoelectrophoresis with an antiserum raised in rabbits against the M protein of the avian N virus proved to be particularly useful for large-scale identification of influenza A virus isolates. Of a total of 231 hemagglutinating agents isolated from 1,656 rectal swabs collected from shore and open-country birds, 158 could be identified as influenza A viruses by counterimmunoelectrophor...
