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 کاملComparative Efficacy of Five Different Brands of Commercial Newcastle Disease Lasota Virus Vaccines in Broilers
Five commercial LaSota strain Newcastle disease (ND) vaccines namely A, B, C, D and E were evaluated for their potency, efficacy, thermostability and influence on productivity in broilers. A 3-log10 difference of EID50 and two-to-eight fold difference of HA activity was found among the various vaccines tested. One hundred and fifty day-old broiler chicks were divided into six equal groups tagge...

The present study was designed to investigate effects of Lisovit (Biomin, Austria) on the immune system of broiler chickens. For this purpose, 270 (day-old) broiler chicks were randomly divided into three groups A, B and C of 90 birds each. The birds were vaccinated against Newcastle Disease (ND) on day 3 (intraocular) and day 18 (drinking water) of age and against Infectious Bursal Disease (IB...
