The Anti-Porcine Parvovirus Activity of Nanometer Propolis Flavone and Propolis Flavone In Vitro and In Vivo

Figure 5

The variation of HI antibody titer in every group after challenge (log2). Bars in the same mode marked without the same superscripts differ significantly and in the same time differ significantly between NPF and PF (). NPF, nanometer propolis flavone; PF, propolis flavone; DoseH, high dose; DoseM, middle dose; DoseL, low dose; CC, challenged control.
