A Thoroughbred stallion suspected of having venereal disease was found to have an infection of the accessory sex glands. Purulent debris, blood, and Pseudomonas aeruginosa were recovered from all ejaculates. Treatment with gentamicin sulfate, tobramycin, and amikacin sulfate was unsuccessful in eliminating the infection. The stallion's seminal plasma, collected during treatment with gentamicin sulfate, did not contain any appreciable antibacterial activity. Apparently, negligible amounts of gentamicin diffused across the mucosal cell borders of the accessory sex glands into the seminal plasma. Bilateral seminal vesiculitis and ampullitis were evident on examination of the reproductive tract when the stallion was euthanatized.
