Comparative Efficacy of Oculonasal and Intranasal Routes of Vaccination in Induction of Immune Response against Newcastle Disease Virus
Vaccination programs to control Newcastle disease include use of low virulent live virus vaccines or inactivated vaccines to induce protective immunity. In order to further characterize the immune response elicited by live virus, we evaluated both cellular and humoral immune response to Newcastle disease virus (NDV) consequent to vaccine application by oculonasal and intranasal routes. Specific...
متن کاملVaccination against Newcastle Disease in the Hatcheries
Vaccination has an important role in the prevention of ND even though an ideal vaccination program can not be easily given as it would depend on level of challenge in the field, disease control polices in the country, type of birds (broilers or layers), vaccine strain, size of the flock, past performance of vaccination programs etc. However, the vaccination in the hatcheries has been used throu...
متن کاملEfficacy of CpG-ODN Administration Routes on Humoral Responses against Newcastle disease in Broilers
Un-methylated cytosine-phosphate-guanosine oligodeoxynucleotides (CpG-ODN) has been considered as a powerful vaccine adjuvant and recognition of CpG-ODN by chicken leukocytes promotes their ability to fight against infections. In our study, efficacy of different routes of CpG-ODN application as an adjuvant on immune responses (antibody titer together with leukogram) following vaccination agains...
متن کاملEvaluation of Two Vaccination Schemes Using Live Vaccines against Newcastle Disease in Chickens
The use of different types of Newcastle disease (ND) vaccine in different vaccination schemes has decreased the incidence of velogenic Newcastle disease (VND) in commercial poultry worldwide. In under-developed countries like Pakistan, these vaccination schemes are not successful due to free-range and backyard poultry production. This trial was conducted in 90 experimental chickens to develop a...
متن کاملMycoplasma synoviae infection on Newcastle disease vaccination of chickens
Newcastle disease is characterized by respiratory manifestations in association with nervous and/or digestive symptoms. Its prevention is done by vaccination with live attenuated (lentogenic strains) and/or killed vaccines. The lentogenic strains can lead to strong post-vaccination reaction, principally due to the presence of other pathogenic agents. Among them, Mycoplasma synoviae is worldwide...
