    • T. suis is the whipworm of pigs, which has a direct life cycle. Bipolar eggs are passed in the feces, ingested by a pig, and larvae hatch within crypts of Lieberkuhn in the intestine and cecum. The anterior end of adults are embedded in the mucosa and severe infections can result in diarrhea, anemia, and death in young animals with severe infections, and diminished weight gain n older animals. T. suis can hatch within the human gut, but clinical infections are not seen.
