If one were to feed them a vial of trichuris suis, I imagine they would implant in the pig.  I don’t know the longevity of the pig whipworm, or the methods one would have to take in order to isolate the ova from the pig’s feces in order to avoid contamination and ingesting any fecal flora that one wouldn’t desire, but with a little research, I imagine it would be possible.  The pig whipworm was chosen since pig farmers have been exposed to this organism for a long time and were considered asymptomatic.  It could also be protective to people’s children, as contact with farm animals  is associated with a decrease in pediatric crohn’s disease.

I wonder if using cow or horse manure on vegetable crops would be protective?

If anyone experiments with this idea; gets a pig and isolates the pig whipworm, please share with us your methods.

In their pipeline, they claim that they were starting a trial for Crohn’s disease this Fall, but I contacted the CEO and he said due to funding issues, it’s been postponed, and to look for an announcement on clinicaltrials.gov for when the trial begins. So for those with Crohn’s waiting for some free TSO, it may be a while…
