Two 83-day-old pigs presented with emaciation, and were euthanized for laboratory examination. Severe extensive ulcerative colitis was observed in the animals, and a very large number of trophozoites were seen at the lesion. These parasites were genetically identified as E. polecki subtype 3. Through pathological, bacteriological, and virological analyses, it was suggested that the parasite could be associated with the ulcerative colitis in these pigs.
