Experimental Infection of Turkeys with A Virulent Newcastle Disease Virus Isolated from Broiler Chickens
Newcastle disease (ND) is a highly contagious infection of many avian species, mainly chickens and turkeys, with a devastating impact on worldwide poultry production. The ND accounts for heavy losses in Iranian poultry flocks. There are some reports regarding the epidemiology of this infection in Iran. This study was performed to investigate the infection of turkeys with a Newcastle disea...
متن کاملSequence analysis of the VP1 gene in three very virulent Iranian infectious bursal disease virus strains
Infectious bursal disease (IBD) is a highly contagious disease of chickens caused by the infectious bursal disease virus (IBDV). This study was conducted to characterize three IBDV strains from Iran. A reverse transcriptase-polymerase chain reaction (RT-PCR) procedure was used to amplify a 715-bp fragment of the VP1 gene from IBDV strains. Amplified VP1 fragments of the three Iranian IBDV strai...
متن کاملComplete Genome Sequence of a Velogenic Newcastle Disease Virus Isolated from an Apparently Healthy Village Chicken in South India
We report the complete genome sequence of a Newcastle disease virus (NDV) isolate, NDV-D1/1998, from an apparently healthy village chicken in South India. This class II, genotype II virus is 15,186 nucleotides in length with unique amino acid variations and was found to be a velogenic pathotype by standard pathogenicity tests.
متن کاملNucleotide sequence of the phosphoprotein (P) gene of Newcastle disease virus (strain Beaudette C).
The phosphoprotein, or P protein, of Newcastle disease virus is required for transcription of the viral genome (1) and is the major product of the P gene (2). The cDNA for the complete P gene of Newcastle disease virus (strain Beaudette C) was cloned and sequenced in both directions by using Bal-3 1 and restriction endonuclease subcloning. The largest open reading frame of the P gene codes for ...
متن کاملSequence Analysis of Fusion Gene of Newcastle Disease Viruses Isolated from Ostrich (Struthio camelus) in Iran, 2012
Background and Aims: Newcastle disease virus (NDV) infection have been established in at least 241species of birds representing 27 of the 50 orders of the class.NDV isolate were obtained from infected ostrich flock during the outbreaks of ND in Iran 2012. The F gene fragment which codes the main functional region of the F protein was obtained by RT-PCR and sequenced. Methods: From the pathotype...
