Orchitis, goat

    Bilateral orchitis in a breeding buck presented for poor reproductive performance. Ultrasonographic examination of the testes (right) showed hyperechoic nodules and several pockets of fluid in both testicles. Fine needle aspiration and microbial culture of specimens from the lesions revealed Corynebacterium pseudotuberculosis infection.
