Urogenital infections and vaginal discharge are common complaints of swine producers and breeding herd managers. This is an area of great concern, not only for producers but also for swine veterinarians. This syndrome has been on the increase in recent years and is associated with intensive management of swine. Some of the manifestations of this syndrome are reproductive failure, poor performance, inappetence, and underconditioned sows. This is a source of great economic loss to the producer as reproductive efficiency is one of the most accurate predictors of swine enterprise profitability. Even so published information on this syndrome has only been available in recent years and is anything but plentiful.
