Simian agent 8 (SA8) is a neurotropic, endemic alphaherpesvirus in Papio sp. Lesions associated with simian agent 8 infections usually involve the genitalia of sexually mature baboons. In females, secondary bacterial infections may lead to scarring of the vulva and perineum, with resulting vaginal obstruction. Affected baboons are poor breeders and often develop urinary tract infections due to retention of urine in the vagina. Reconstructive vaginal surgery was performed on seven baboons with vaginal obstruction. Four weeks before surgery, 50 mg of Depo-Provera® was administered intramuscularly to each animal to arrest the estrous cycle, reduce swelling, and allow adequate surgical exposure of the vagina. Ventral and circular incisions were made around the constricted vagina. The peripheral skin was excised to break down the underlying connective tissue, allowing access to the vaginal mucosa. Healthy vaginal tissue was then opposed to the incised skin edges with 3-0 Vicryl in an interrupted pattern. Once healed, the vaginas remained patent, allowing normal mating and urination. Nine months after surgery, five baboons had healthy infants, and pregnancy was confirmed in the other two animals. The described procedure may allow female baboons previously infertile and at risk of urinary tract infections to be returned to a healthy reproductive state.
