Brucella ovis infection

Brucella ovis infection

Brucella ovis or contagious epididymitis is a sexually transmitted disease of rams that causes infection and distortion of the testis, which produces sperm, and the epididymis, which is a coiled tube that stores and matures the sperm. B. ovis reduces a ram’s fertility. About 3% of New Zealand flocks have the disease. The diseased testicle (left) is enlarged in comparison with the normal one (right).
