Fungal peritonitis (A-D), Pseudomonas aeruginosa peritonitis (E, F), and Serratia marcescens peritonitis (G, H) show exudation of fibrin on the surface of peritoneal membrane associated with inflammatory cell infiltration. B, D, F, and H are serial sections of panels A, C, E, and G, respectively. C and D show higher-magnification images of the boxed areas in A and B. Black and blue arrows indicate the same areas in serial sections. A, C, E, and G: HE staining; B, D, F, and H: PTAH staining. Scale bars in A and B = 200 μm. Scale bars in C to H = 100 μm.
