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

Comparison of pathogenicity and immunogenicity of two strains (TCND and Montana) of Newcastle disease virus propagated in four tissue cell types

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.

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...

Studies on the immunogenic properties of three lentogenic strains of newcastle disease virus

Humoral Immune Response Induced by PLGA Micro Particle Coupled Newcastle Disease Virus Vaccine in Chickens

This experiment was conducted for evaluating the humoral immune responses induced by Poly Lactide-co-Glycolide Acid (PLGA) microspheres coupled inactivated Newcastle Disease Virus (NDV) vaccine in comparison to an ‘in-house’ prepared inactivated and a live commercial vaccine. PLG microparticles containing inactivated NDV were prepared by a double emulsion technique based on solvent evaporation ...

The response of ducks to V4 Newcastle disease virus and its transmission to contact ducks and domestic chickens

Experimental infection of Muscovy ducks with V4 strain of Newcastle disease virus was undertaken to determine the response of the ducks to the virus and the possibility of virus transmission to ducks and chickens in village like conditions. Twelve ducks were randomly and equally divided into three groups of control, inoculated and in-contact. Additionally, the chickens were placed into two grou...
