Characterization of the Immune Response Induced by a Commercially Available Inactivated Bluetongue Virus Serotype 1 Vaccine in Sheep
The protective immune response generated by a commercial monovalent inactivated vaccine against bluetongue virus serotype 1 (BTV1) was studied. Five sheep were vaccinated, boost-vaccinated, and then challenged against BTV1 ALG/2006. RT-PCR did not detect viremia at any time during the experiment. Except a temperature increase observed after the initial and boost vaccinations, no clinical signs ...
متن کاملImmunogenicity of commercial, formaldehyde and binary ethylenimine inactivated Newcastle disease virus vaccines in specific pathogen free chickens
Newcastle disease (ND) is one of the most important diseases that affect birds; the epizootic nature of the disease has caused severe economic losses in the poultry industry worldwide. In this experiment ND virus (NDV) was inactivated by two different chemicals binary ethylenimine (BEI) and formaldehyde. Formaldehyde was used at 0.1%, while BEI was used at concentrations of 1 to 4 mM. NDV inact...
متن کاملBinary Ethylenimine Inactivated Japanese Encephalitis Virus Antigen Reveals Hemagglutination
Severe climate change and global warming may impact significantly on vector-borne disease including Japanese encephalitis (JE) infection in human and animals. Thus, veterinary authority requires large quantity of diagnostic tools to survey vector-borne diseases. New producing method having a relation with JE antigen is needed to substitute conventional sucrose-acetone extraction method using su...
متن کاملImmune Response to Inactivated Newcastle Disease Virus by Electrolysed Catholyte Anolyte and Binary Ethylenimine in Specific Pathogen Free Chickens
This study aimed to investigate the immunogenicity of Newcastle disease virus (NDV) in specificpathogen-free (SPF) chickens. The NDV was inactivated using either Binary ethyleneimine (BEI) or Electrolysed water-Catholyte-Anolyte (ECA). Complete inactivation of NDV occurred after 24 hours with either BEI or ECA. Prepared inactivated NDV vaccines were tested for their efficiency in generating hum...
متن کاملHumoral 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 ...
