| Abstract |
We developed a novel vaccine platform utilizing Bifidobacterium as an antigen delivery vehicle for mucosal immunization. Genetically modified Bifidobacterium longum displaying Salmonella-flagellin on the cell surface was constructed for the oral typhoid vaccine. The efficiency of this vaccine was evaluated in a murine model of typhoid fever. We then orally administered 2.5 × 10(7) CFU of the recombinant Bifidobacterium longum (vaccine) or parental Bifidobacterium longum, or PBS to BALB/C mice every other day for 2 weeks. After the administration, a total of 42 mice (14 mice in each group) were challenged with Salmonella Typhimurium (1.0 × 10(7) CFU/mouse). While 12 mice in the PBS group, and 9 in the parental Bifidobacterium longum group died (median survival: 14 and 25 days), only two in the vaccine group died. These data support that our genetically modified Bifidobacterium antigen delivery system offers a promising vaccine platform for inducing efficient mucosal immunity. |
