Plaque formation in the aortic root. (A) Representative aortas from P. gingivalis-infected and sham-infected mice were stained with HE and oil red O (40× magnification). (B and C) Atherosclerosis of aortic section was expressed in terms of plaque area and percentage of the total area (n = 6 mice per group). Lesion areas of P. gingivalis-infected ApoE–/– mice were larger than those of uninfected ApoE–/– mice. * P < 0.0125 versus C57, Bonferroni correction, α = 0.05/4. ** P < 0.0125 versus ApoE–/–, Bonferroni correction, α = 0.05/4. Pg = Porphyromonas gingivalis.
