Overview

To enhance the efficacy of the current Newcastle disease vaccine, we have tested two potential adjuvants (Imiquimod and ODN-1826) in chickens. Birds were treated with PBS, Imiquimod or ODN-1826 (50 µg/bird) or vaccinated intranasally with live LaSota strain with or without Imiquimod or ODN-1826 (50 µg/bird). Two weeks after vaccination, birds were challenged with virulent New-castle disease virus (chicken/CA/212676/2002). The experimental setting was a laboratory with animal care as approved by the institutional animal care and use committee as appropriate for the species and age of bird. Data are the serum antibody titers to the vaccine or challenge virus as determined by hemagglutination inhibition assay. Virus shedding titers by the oral and cloacal route for individual birds exposed to virulent Newcastle disease virus were determined by quantitative real-time RT-PCR. Expression of antiviral genes from tissues collected at 1 and 3 days after treating 2 week old SPF chickens with adjuvant and/or vaccines were determined by quantitative PCR.
