Mycobacterium phlei as an oral immunomodulator with Newcastle disease vaccine.
Experiments were conducted in chickens to understand the effects of oral immunomodulation. Heat inactivated M phlei, a commensal Mycobacterium and a non-specific immunomodulator, was administered orally prior to live Newcastle disease F (ND F) strain vaccination. In experimental birds it lead to an enhanced cell mediated Immune response (CMI) against the vaccine. There was a reduction in the Ha...
متن کاملNewcastle Disease Virus Vectored Bivalent Vaccine against Virulent Infectious Bursal Disease and Newcastle Disease of Chickens
Newcastle disease virus (NDV) strain F is a lentogenic vaccine strain used for primary vaccination in day-old chickens against Newcastle disease (ND) in India and Southeast Asian countries. Recombinant NDV-F virus and another recombinant NDV harboring the major capsid protein VP2 gene of a very virulent infectious bursal disease virus (IBDV); namely rNDV-F and rNDV-F/VP2, respectively, were gen...
متن کاملEfficacy of thermostable I-2 Newcastle disease vaccine compared to B1 commercial vaccine in broiler chicken
Frequent vaccination failures have occurred in the broiler farms in Eurasian countries during Newcastle disease outbreaks. The disease is enzootic in many countries of the region, especially in southwest Asia. I-2 vaccine has been used successfully in village chickens in many Asian and African countries. Our preliminary study showed good efficacy of the vaccine in broiler chickens. Therefore th...
متن کاملCaution about Newcastle disease virus-based live attenuated vaccine.
In several recent papers, two published last year in the Journal of Virology by DiNapoli et al. (3) and Ge et al. (4), an earlier study by Martinez-Sobrido et al. in 2006 (6), and a review by Bukreyev et al. in 2006 (1), Newcastle disease virus (NDV) is proposed as a potential vector in the development of a novel bior multivalent vaccine. We question whether those studies satisfactorily address...
متن کاملDevelopment of a virosome vaccine for Newcastle disease virus.
In an effort to protect chickens against Newcastle disease (ND), a nonreplicating virosome vaccine was produced by solubilization of Newcastle disease virus (NDV) with Triton X-100 followed by detergent removal with SM2 Bio-Beads. Biochemical analysis indicated that the NDV virosomes had similar characteristics as the parent virus and contained both the fusion and hemagglutinin-neuraminidase pr...
