Abstract
Specimens of colonic mucosa from two pigs with diarrhea were examined by light and electron microscopy. The epithelial surfaces of both pigs were extensively colonized by large spirochetes morphologically compatible with Treponema hyodysenteriae or Treponema innocens. The microorganisms were intimately attached end-on to the luminal cells. A weakly beta-hemolytic spirochete similar to T. innocens was isolated from the colon of one of the pigs.
