Porcine colonic spirochetosis (PCS), a nonfatal diarrheal disease of grower-finisher pigs, is caused by the intestinal spirochete Serpulina a pilosicoli. 1 Recent advances in genetic-based diagnostic methods have expanded the available information on intestinal spirochetes and their role in porcine colonic diseases. Pigs affected with PCS have depressed average daily gains and feed efficiencies in the grower-finisher stages. Diagnosis is based on clinical signs, histopathology, and isolation of the causative agent. The same treatment regimens used for diseases caused by the related spirochete Serpulina hyodysenteriae are the most effective but are not consistently successful. Implementing all-in/all-out pig flow, strict hygiene, and ration changes can control PCS.
