Induction of significant protection against F. nucleatum by immunization with F. nucleatum-AhpC vaccine. Mice were immunized by intraperitoneal injection (A) or intragastric administration (B) with PBS, AhpC or AhpC combined with alum or cholera toxin (CT). One week after the final vaccination, the mice were challenged with F. nucleatum and colonization quantified using qPCR assay. *P < 0.05, **P < 0.01.
