Infectious Diseases in Breeding Stallions

A wide variety of infectious bacterial, viral, and protozoal reproductive pathogens have the potential to be transmitted by the breeding stallion. In addition, nonvenereal diseases can also be spread due to the close proximity of mares and stallions during natural service. Disease spread by assisted breeding techniques is also possible. The equine veterinarian must develop a thorough understanding of the relevant diseases and be able to formulate treatment and management plans to minimize the effects of infection on breeding programs.
