Mucosal surface provide portal entry for a majority of infectious agents. Hence, protection at the mucosal surface through immunization plays an important role in containing its systemic spread. Mucosal vaccination of chicken at early stages of life with live attenuated strain of Newcastle disease virus (NDV) induces both cellular and humoral immune responses against the Newcastle disease. In o...
The HI and SN titers produced by V2 (Laso ta Vaccine, chick-embryo origin) were more than VI (TCND) and V3 (Lasota tissue culture origin) vaccines. High percentage (96,%, 93,% & 90,%) of the three subgroup hens, when vaccinated with VI, V2 and V3 respectively, were found resistant to contact exposure challenge with 2 x 10 6 ELD 50 of virulent NDV Zabol strain. The egg production dropped slightl...
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 ...
