Long Antibody Persistence and Transgenerational Transfer of Immunity in a Long-Lived Vertebrate

摘要: AbstractAlthough little studied in natural populations, the persistence of immunoglobulins may dramatically affect dynamics immunity and ecology evolution host-pathogen interactions involving vertebrate hosts. By means a multiple-year vaccination design against Newcastle disease virus, we experimentally addressed whether levels specific antibodies can persist over several years females long-lived procellariiform seabird—Cory’s shearwater—and maternal that antigen could long period offspring after mother was exposed. We found single led to high for transmitted their persisted weeks hatching even 5 vaccination. The temporal maternally transferred nestlings highly dependent on level at hatching. A second boosted efficiently th...
