ABSTRACT
In order to determine the comparative efficacy of injectable and intranasal vaccines to stimulate Bordetella bronchiseptica (Bb)-reactive anamnestic antibodies, a trial was conducted using 144 adult household dogs of various breeds and ages, which had been previously administered intranasal Bb vaccine approximately 12 months before enrollment. Dogs were randomized into 2 groups and blood, nasal swabs, and pharyngeal swabs were collected prior to the administration of single component Bb vaccines intranasally or parenterally. Ten to 14 days later all dogs were resampled to measure changes in systemic and local antibody to Bb. There were no differences in the changes in Bb-reactive serum IgG and nasal IgA between the groups, whereas intranasally vaccinated dogs had significantly higher Bb-reactive serum IgA. These data indicate that both of the current generation of intranasal (modified-live) and injectable (acellular) Bb vaccines can stimulate anamnestic local and systemic antibody responses in previously vaccinated, Bb-seropositive adult household dogs.
Efficacité comparative des vaccins intranasaux et injectables pour stimuler les réponses des anticorps anamnestiques réagissant àBordetella bronchisepticachez les chiens domestiques. Afin de déterminer l'efficacité comparative des vaccins injectables et intranasaux pour stimuler les anticorps anamnestiques réagissant à Bordetella bronchiseptica (Bb), un essai a été réalisé à l'aide de 144 chiens domestiques adultes de diverses races et d'âges différents, auxquels l'on avait déjà administré le vaccin Bb intranasal environ 12 mois avant le recrutement. Les chiens ont été assignés au hasard à deux groupes et des échantillons sanguins, et écouvillons nasaux et pharyngés ont été prélevés avant l'administration de vaccins Bb à composant unique soit par voie intranasale ou parentérale. Dix à 14 jours plus tard, on a prélevé de nouveaux échantillons pour tous les chiens afin de mesurer les changements dans les anticorps systémiques et locaux pour Bb. Il n'y avait aucune différence au niveau des changements pour l'IgG sérique et l'IgA nasal réactif à Bb entre les groupes, tandis que les chiens vaccinés par voie intranasale présentaient un niveau significativement supérieur d'IgA sériques réactives à Bb. Ces données indiquent que les deux générations actuelles de vaccins Bb intranasal (vivant modifié) et injectable (acellulaire) peuvent stimuler les réponses locale et systémique des anticorps Bb chez les chiens adultes domestiques antérieurement vaccinés.(Traduit par Isabelle Vallières).
