Figure 2. . Results of immunohistochemical staining using monoclonal antibody 6G2 and the ABC complex technique of liver and intestine samples from young rabbits infected with rabbit hemorrhagic disease virus (RHDV) isolate RHDV-N11 and control rabbits. A) Liver of RHDV-N11–infected rabbit. Hepatocytes show intense 6G2-specific immunolabeling. Scale bar = 50 µm. B) Intestinal villi in small intestine of RHDV-N11–infected rabbit. Areas of focal necrosis and epithelial cells show strong immunolabeling. Scale bar = 20 µm. C) Liver of control rabbit. Hepatocytes do not show positive immunolabeling. Scale bar = 50 µm. D) Epithelial cells of intestinal villi of control rabbit do not show positive results on staining. Scale bar = 100 µm.
