Neuropathogenic Capacity of Lentogenic, Mesogenic, and Velogenic Newcastle Disease Virus Strains in Day-Old Chickens

Immune response of chickens to four lentogenic strains of Newcastle disease virus propagated in lamb kidney cell cultures

Plaque assay for avirulent (lentogenic) strains of Newcastle disease virus.

Avirulent (lentogenic) strains of Newcastle disease virus form plaques on chicken embryo lung monolayers in 48 to 72 h.

Efficacy 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...

Recombinant Immunomodulating Lentogenic or Mesogenic Oncolytic Newcastle Disease Virus for Treatment of Pancreatic Adenocarcinoma

Oncolytic Newcastle disease virus (NDV) might be a promising new therapeutic agent for the treatment of pancreatic cancer. We evaluated recombinant NDVs (rNDVs) expressing interferon (rNDV-hIFNβ-F₀) or an IFN antagonistic protein (rNDV-NS1-F₀), as well as rNDV with increased virulence (rNDV-F₃aa) for oncolytic efficacy in human pancreatic adenocarcinoma cells. Expression of additional proteins ...
