Induction of Intestinal Immune Response to Lentogenic Vaccine Strain of Newcastle Disease Virus in Chicken
Mucosal surface provide portal entry for a majority of infectious agents. Hence, protection at the mucosal surface through immunization plays an important role in containing its systemic spread. Mucosal vaccination of chicken at early stages of life with live attenuated strain of Newcastle disease virus (NDV) induces both cellular and humoral immune responses against the Newcastle disease. In o...
متن کاملTranscriptional Innate Immune Response of the Developing Chicken Embryo to Newcastle Disease Virus Infection
Traditional approaches to assess the immune response of chickens to infection are through animal trials, which are expensive, require enhanced biosecurity, compromise welfare, and are frequently influenced by confounding variables. Since the chicken embryo becomes immunocompetent prior to hatch, we here characterized the transcriptional response of selected innate immune genes to Newcastle dise...
متن کاملEvaluation and Comparison of the Potential Immunogenicity of Two Commercial Inactivated Bivalent Newcastle and Avian Influenza Vaccines in SPF Chicken
In the present study, the potency and immunogenicity of the inactivated bivalent vaccine of Newcastle disease (ND) and avian influenza (AI) produced by Razi institute in Iran were compared with a similar imported vaccine administered by standard methods to specific-pathogen-free (SPF) chicken. A total of 150 twenty-one-day-old SPF chickens were used for evaluating Razi and imported inactivated ...
متن کاملAntigen Localization Influences the Magnitude and Kinetics of Endogenous Adaptive Immune Response to Recombinant Salmonella Vaccines
The use of recombinant attenuated Salmonella vaccine (RASV) strains is a promising strategy for presenting heterologous antigens to the mammalian immune system to induce both cellular and humoral immune responses. However, studies on RASV development differ on where heterologous antigens are expressed and localized within the bacterium, and it is unclear how antigen localization modulates the i...
متن کاملChicken cecum immune response to Salmonella enterica serovars of different levels of invasiveness.
Day-old chicks are very susceptible to infections with Salmonella enterica subspecies. The gut mucosa is the initial site of host invasion and provides the first line of defense against the bacteria. To study the potential of different S. enterica serovars to invade the gut mucosa and trigger an immune response, day-old chicks were infected orally with Salmonella enterica serovar Enteritidis, S...
