Newcastle Disease Virus Vectored Bivalent Vaccine against Virulent Infectious Bursal Disease and Newcastle Disease of Chickens
Newcastle disease virus (NDV) strain F is a lentogenic vaccine strain used for primary vaccination in day-old chickens against Newcastle disease (ND) in India and Southeast Asian countries. Recombinant NDV-F virus and another recombinant NDV harboring the major capsid protein VP2 gene of a very virulent infectious bursal disease virus (IBDV); namely rNDV-F and rNDV-F/VP2, respectively, were gen...
متن کاملEfficacy of inactivated velogenic Newcastle disease virus genotype VII vaccine in broiler chickens
Newcastle disease (ND) causes severe economic losses in poultry production. Despite the intensive vaccination regimes of NDV in Egypt, many outbreaks are being reported. The present study focused on the preparation and evaluation of inactivated velogenic Newcastle disease virus vaccine (genotype VII) isolated from Egyptian broiler chicken during 2015-2016. Fifty-five tissue samples including tr...
متن کاملNewcastle disease virus expressing H5 hemagglutinin gene protects chickens against Newcastle disease and avian influenza.
Newcastle disease virus (NDV)-expressing avian influenza virus (AIV) hemagglutinin (HA) of subtype H5 was constructed by reverse genetics. A cloned full-length copy of the genome of the lentogenic NDV strain Clone 30 was used for insertion of the ORF encoding the HA of the highly pathogenic AIV isolate A/chicken/Italy/8/98 (H5N2) in the intergenic region between the NDV fusion and hemagglutinin...
متن کاملEfficacy of Thermostable Newcastle Disease Virus Strain I-2 in Broiler Chickens Challenged with Highly Virulent Newcastle Virus
Newcastle disease (ND) is a major threat to poultry industry production throughout developing countries. The Newcastle disease viruses (NDVs) infecting industrialized and indigenous poultry in Iran are velogenic strains and responsible for the frequent outbreaks of ND in poultry farms even in vaccinated flocks causing serious economic losses in the commercial and indigenous poultry. However, va...
متن کاملEvaluation of Two Vaccination Schemes Using Live Vaccines against Newcastle Disease in Chickens
The use of different types of Newcastle disease (ND) vaccine in different vaccination schemes has decreased the incidence of velogenic Newcastle disease (VND) in commercial poultry worldwide. In under-developed countries like Pakistan, these vaccination schemes are not successful due to free-range and backyard poultry production. This trial was conducted in 90 experimental chickens to develop a...
