In the present study, binding of bovine lactoferrin to bifidobacteria was demonstrated. This is the first report showing the binding of bovine lactoferrin to Bifidobactesrium spp. under a transmission electronic microscope using biotinylated bovine lactoferrin and gold-conjugated streptavidin. In addition, we confirmed that bovine lactoferrin-binding protein exists on the surface of bifidobacteria.
