Immunohistochemistry in the scrotal skin, pampiniform plexus and testicular parenchyma from acutely and chronically infected bulls. A Widespread presence of T-lymphocytes (CD3 + cells) associated with blood vessels in the scrotal skin from a acutely infected bull with juveniles cysts (bull no. 6); B CD3 + T-lymphocytes surrounding tissue cysts in the pampiniform plexus from a chronically infected bull (bull no. 10); C Diffuse presence of macrophages (iba-1 + cells) in focal areas of vasculitis and surrounding juvenile tissue cysts in the scrotal skin of an acutely infected bull (bull no. 3); D iba-1 + macrophages surrounding tissue cysts without diffuse inflammation in the pampiniform plexus of a chronically infected bull. (bull no. 10); E CD3 + T-lymphocytes surrounding tissue cysts in the scrotal skin from a chronically infected bull (bull no. 10); F Immunohistochemical detection of several active macrophages MAC387 + surrounding tissue cysts in the testicular parenchyma from a chronically infected bull (bull no. 10).
