Efficacy 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 کاملEffect of Pigeon Origin Newcastle Disease Virus on Various Liver Enzymes and Associated Pathological Changes in Experimentally Infected Pigeons
Newcastle disease virus (NDV) was isolated from a field outbreak in pigeons. The virus was characterized by haemagglutination test (HA) and confirmed by haemagglutination inhibition test (HAI). The pathotyping was done by mean death time (MDT), intracerebral pathogenicity index (ICPI) and intravenous pathogenicity index (IVPI). The ELD50 of the velogenic strain was 10/0.1 ml. Thirty-nine pigeon...
متن کاملExperimental infection with Brazilian Newcastle disease virus strain in pigeons and chickens.
This study was designed with the goal of adding as much information as possible about the role of pigeons (Columba livia) and chickens (Gallus gallus) in Newcastle disease virus epidemiology. These species were submitted to direct experimental infection with Newcastle disease virus to evaluate interspecies transmission and virus-host relationships. The results obtained in four experimental mode...
متن کاملNewcastle disease virus-infected splenocytes express the proopiomelanocortin gene
Infection of murine splenocytes with Newcastle disease virus results in expression of the proopiomelanocortin gene as determined by dot and northern blot analysis of total cellular and poly(A)+ cytoplasmic RNA. These data provide the first evidence that the precursor protein for adrenocorticotropin and beta-endorphin can be synthesized by lymphoid cells.
متن کاملGenetic diversity of newcastle disease virus in wild birds and pigeons in West Africa.
In West and Central Africa, virulent Newcastle disease virus (NDV) strains of the recently identified genotypes XIV, XVII, and XVIII are enzootic in poultry, representing a considerable threat to the sector. The increasing number of reports of virulent strains in wild birds at least in other parts of the world raised the question of a potential role of wild birds in the spread of virulent NDV i...
