The marked progress in recombinant deoxyribonucleic acid (DNA) technology during the past decade has led to the development of a variety of safe new vaccine vectors which are capable of efficiently expressing foreign immunogens. These have been based on a variety of virus types--poxviruses, herpesviruses and adenoviruses--and have led to the production of many new potential recombinant vaccines...

Two mouse monoclonal antibodies (MAbs), viz. 2B7 and 2 D10 raised against haemagglutinin-neuraminidase glycoprotein of Newcastle disease virus (NDV) were used to identify several other field isolates and vaccine strains of NDV. These MAbs reacted specifically with all the NDV strains/isolates in Dot-ELISA whereas, only MAb 2D10 reacted with all the NDV strains/isolates in agar gel precipitation...

wk. Feed consumption, body weight and feed conversion were measured at 2, 4 and 6 wk. Carcass yield and weights of abdominal fat, gizzard and ceca were also determined at 6 wk. All birds were intramuscularly immunized with killed vaccine of Newcastle and Avian Influenza (H9 N2) at 8 d and antibody titer responses to Newcastle and Influenza were determined by hemagglutination inhibition (HI) tes...

In this study Mentofin was used in commercial broiler chickens naturally exposed to infectious bursal disease virus (IBDV) and administered live Newcastle disease virus (NDV) vaccine to evaluate the ability of Mentofin to reduce Escherichia coli-related respiratory lesions, immunomodulate Newcastle disease (ND) vaccine response, change pharyngeal aerobic bacterial counts, and have certain impac...

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 ...
