Porcine intestinal spirochaetosis (PIS) is a diarrhoeal disease of weaners and growers, associated with a mild colitis. Control of the aetiological agent, Serpulina pilosicoli, has relied mainly on the use of antimicrobial agents. In contrast, besides the use of antimicrobials and appropriate management practices, it is our experience that the closely related Serpulina hyodysenteriae (the agent of swine dysentery) can also be partially controlled by bacterin vaccines (1), whilst experimentally-infected pigs totally resist challenge if fed a diet based on cooked white rice and animal protein (4, 5). This diet results in reduced microbial fermentation in the large intestine, and it appears that these conditions inhibit colonisation by the spirochaete. The purpose of the present study was to assess whether the use of a bacterin vaccine or a rice-based diet could similarly inhibit colonisation by S. pilosicoli.
