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 ...
متن کاملHumoral and Cellular Aspects of the Immune Response to the Somatic Antigen of Salmonella Enteritidis
A study was made of the cellular and humoral aspects of the immune response of the rabbit to the somatic polysaccharide of Salmonella enteritidis. The response to a single intravenous injection was characterized by the appearance of elevated titers of bactericidal antibody between 2 and 3 days later. The maximum titer was dose-dependent and occurred between 5 and 7 days, thereafter declining ra...
متن کاملphoP, SPI1, SPI2 and aroA mutants of Salmonella Enteritidis induce a different immune response in chickens
Poultry is the most frequent reservoir of non-typhoid Salmonella enterica for humans. Understanding the interactions between chickens and S. enterica is therefore important for vaccine design and subsequent decrease in the incidence of human salmonellosis. In this study we therefore characterized the interactions between chickens and phoP, aroA, SPI1 and SPI2 mutants of S. Enteritidis. First we...

متن کاملCrop immune response post-Salmonella enteritidis challenge in eight commercial egg-layer strains and specific-pathogen-free White Leghorn chickens.
The crop immune response against Salmonella Enteritidis (SE) challenge in eight commercial egg-layer strains (five white-egg layer and three brown-egg layer) and specific-pathogen-free (SPF) White Leghorn (WL) hens was investigated. Pre- and post-SE challenge mucosal immune responses within the crops were evaluated. Commercial layers and SPF WL hens were orally challenged with 10(8) CFU/ml SE P...
