P. acnes CAMP factor exerted virulence activity. Ears of ICR mice were injected intradermally with recombinant GFP (left ear) and CAMP factors (right ear). (A) Inflammation-induced ear redness (arrow) was visualized 24 hours after injection. (B) Ear swelling was observed in an H&E-stained frozen tissue section of GFP- (a) or CAMP factor- (b) injected ear. The magnification 4× images indicated the dilated veins filled with erythrocytes (arrowheads). Bars (A)= 1 cm. Bars [B(a)]= 2 mm. Bars [B(b)]= 0.5 mm.
