Augmentation of anti-influenza virus hemagglutinin antibody production by Peyer's patch cells with Bifidobacterium breve YIT4064

Abstract

Bifidobacterium breve YIT4064 was tested an an adjuvant for oral influenza vaccine by the murine Peyer's patch cell culture method. The organism augmented production of anti-influenza virus hemagglutinin immunoglobulin A antibody by Peyer's patch cells in response to addition of hemagglutinin. These antibodies may be disseminated to the respiratory mucosal tissue and prevent influenza virus infection.
