Cellular MicroRNA Expression Profile of Chicken Macrophages Infected with Newcastle Disease Virus Vaccine Strain LaSota

Clone Purification, Characterization and Standardization of LaSota Strain for Developing a Live Vaccine against Newcastle Disease Virus

Newcastle disease (ND) is one of the most serious illnesses of chickens. Live vaccines are widely used to prevent chicken from the disease all over the world. To access the effective and potentiate ND vaccine, a homogenous subpopulation from LaSota strain was selected following cultivation of the virus on primary chicken embryofibroblast (CEF) cells. Pathogenicity indices and molecular characte...

Plaque formation of LaSota pathogenic strain of Newcastle disease virus adapted in chick embryo fibroblast cells

In order to adapt LaSota strain of Newcastle disease virus (NDV) on chick embryo fibroblast (CEF) cells, 0.1 ml from LaSota vaccine produced in Razi vaccine and serum research institute inoculated to the CEF cells and was passaged five times in the CEF grown in Eagle’s minimum essential medium (MEM). First to third passages were blind but in fourth passage cytopathic effect of virus was observe...

Newcastle disease virus LaSota strain kills human pancreatic cancer cells in vitro with high selectivity.

CONTEXT Pancreatic cancer is highly resistant to treatment. Previously, we showed that Newcastle disease virus (NDV) strain 73-T was highly cytotoxic to a range of tumor types in vitro and in vivo but the effects of NDV on pancreatic tumors are unknown. We determined the cytotoxicity of the lentogenic LaSota strain of NDV (NDV-LS) toward 7 different human pancreatic tumor cell lines and 4 norma...

Induction of Intestinal Immune Response to Lentogenic Vaccine Strain of Newcastle Disease Virus in Chicken

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...
