Aj. Montes et al., INFERTILITY ASSOCIATED WITH EPERYTHROZOON WENYONII INFECTION IN A BULL, Journal of the American Veterinary Medical Association, 204(2), 1994, pp. 261-263
Infection with Eperythrozoon wenyonii is common in cattle; however, mo
st infections are subclinical. Eperythrozoonosis in bulls can apparent
ly cause a fever and may be associated with edema of the hind limbs an
d scrotum. Edema of the scrotum can interfere with thermoregulation of
the testes, resulting in production of abnormal sperm and low fertili
ty.
