Download or read book In Ovo Immunization of Chickens for Newcastle Disease Virus Using Recombinant Newcastle Disease Viruses written by Valerie C Marcano and published by . This book was released on 2017 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: In ovo vaccination has been used commercially for over 20 years to control avian diseases due to its significant advantages over conventional vaccination. The advantages of in ovo vaccination include a significant reduction in costs, induction of earlier immunity, uniform vaccine delivery, and reduction of stress. In ovo vaccination programs currently available for Newcaste disease virus (NDV) have limitations, including interference by maternal antibodies (MatAbs) and the inability to induce protective immunity until four weeks post vaccination. Current biosecurity measures and vaccination protocols have been unable to stop the occurrence of outbreaks with virulent vNDV around the world particularly in developing countries. Thus, it is imperative to develop new effective vaccines able to overcome the maternal antibody inhibition and confer the earliest protection against vNDV. The poultry industry needs vaccines able to boost both cellular and humoral immune response and to achieve clearance of the challenge virus without compromising the flock's health. In a first set of experiments, attenuated recombinant NDV vaccines containing either an antisense chicken IL-4 insert (ZJ1-L-IL4R), IL-2 expressing variant ( -IL2), IL-10 expressing variant ( -IL-10) or IFNÎđ expressing variant ( -IFNÎđ) were tested as vaccine candidates against homologous challenge with a genotype VIId NDV. Results show that strain ZJ1-L-IL4R may serve as a viable vaccine candidate for in ovo vaccination against NDV, as it compared favorably to the commercial strains regarding protection to challenge, yet displayed lower mortality rates compared with the in ovo live vaccine candidates for NDV. In another set of experiments, we evaluated the modulatory effects of an attenuated recombinant Newcastle disease virus vaccine containing an antisense chicken interleukin 4 insert (IL4R) on the chicken adaptive immune response. Our results did not confirm that the improvement in survival and body weight seen in birds vaccinated with ZJ1-L-IL4R compared to ZJ1-L is due actions by the antisense RNA.

Download or read book Efficacy of Newcastle Disease Virus Vaccines in Broiler Chickens written by Mohammad Showkat Mahmud and published by LAP Lambert Academic Publishing. This book was released on 2013-01 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Newcastle disease is a highly contagious viral disease affecting many domestic and wild avian species that have severe impact on poultry industry.It can also be transmitted to humans that cause conjunctivitis and flu like symptoms. Effective vaccination of flock is the means to control this disease. This book was to investigate persistence of maternal antibody as well as the comparative efficacy of Avinew and BCRDV vaccines against Newcastle disease in chicks. Birds of groups A and B were primarily and secondarily vaccinated with Avinew and BCRDV respectively at the age of day 3 and 20. Sera samples were obtained from 10 randomly selected birds on each occasion of day 1, 10, 17, 27, 30, 34 and 44 of age of birds. Birds of group C were maintained as unvaccinated control for the determination of existence of maternal antibody. Thus it was indicated that performance of Avinew in respect of elucidation of HI antibody was comparatively better than that of BCRDV and maternal antibody against NDV in chicks persisted to a minimal until the age of day 27 and none at day 30 or 34. This analysis will be useful to professionals working for poultry industry, researcher and vaccine manufacturer.
