Immunohistochemistry (IHC) analysis of small-intestine sections in the peak of stage. The villous enterocytes of PDCoV-inoculated pigs were stained brown and black by DAB. This phenomenon demonstrated that PDCoV antigen was detected in the villous enterocytes of PDCoV-inoculated pigs at the peak of stage and examples of positive staining are presented in Fig. 5a, b and c. (a) the duodenum slides of the experiment group (× 80); (b) the jejunum slides of the experiment group (× 80); (c) the ileum slides of the experiment group (× 80); (d) the duodenum slides of the mock-control group (× 80); (e) the jejunum slides of the mock-control group (× 100); (f) the ileum slides of the mock-control group (× 140)
