FC-16 Clinical and immunological effects of Newcastle disease virus vaccine on bovine papillomatosis

Newcastle 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...

Effects of High Dietary Levels of Selenium and Copper on Growth Performance, Selected Blood Biochemical Parameters and Antibody Production Against Newcastle Disease Vaccine Virus in Broiler Chickens

An experiment was conducted to evaluate the effects of high dietary levels of selenium (as sodium selenite) and copper (as copper sulphate) on growth performance, serum biochemical parameters and antibody production against Newcastle disease vaccine (NDV) virus in broiler chickens. A total of 160 Ross 308 unsexed day old broiler chickens were randomly allocated into four treatment groups (n=40 ...

Efficacy of inactivated velogenic Newcastle disease virus genotype VII ‎vaccine in broiler chickens

Newcastle disease (ND) causes severe economic losses in poultry production. Despite the intensive vaccination regimes of NDV in Egypt, many outbreaks are being reported. The present study focused on the preparation and evaluation of inactivated velogenic Newcastle disease virus vaccine (genotype VII) isolated from Egyptian broiler chicken during 2015-2016. Fifty-five tissue samples including tr...

A Comparative Study on Histopathologic Effects of Iranian Newcastle Disease Virus Isolates

Effects of Chicken Interferon Gamma on Newcastle Disease Virus Vaccine Immunogenicity

More effective vaccines are needed to control avian diseases. The use of chicken interferon gamma (chIFNγ) during vaccination is a potentially important but controversial approach that may improve the immune response to antigens. In the present study, three different systems to co-deliver chIFNγ with Newcastle disease virus (NDV) antigens were evaluated for their ability to enhance the avian im...
