Representative histopathological and immunohistochemistrical examination of immunized pigs challenged with CSFV Shimen strain. Various tissues (spleen, kidney, submandibular lymphatic nodes and inguinal lymph nodes) were collected for histopathological evaluation (a) and immunohistochemistry study (b) with CSFV polyserum as primary antibody.
