Orchitis and epididymitis

Orchitis and epididymitis in a bull. There is obvious diffuse fibrous proliferation and small nodules disseminated through the testicular parenchyma, particularly predominant near the tail of the epididymis. The seminiferous tubules exhibit degeneration. In the histology image, on the right, a Besnoitia cyst can be seen surrounded by inflammatory reaction (H&E, 100x).
