> BirdieDear Birdie - I cannot answer your question but can offer some
observations. The first deals with the peach. Each Trichuris egg
ingested results in one adult worm. Of course not all eggs ingested will
hatch and not all hatched larvae will survive to adulthood. The worms do
not multiply in the body, each must come from an ingested egg. The type
of symptoms you describe would require a heavy worm burden
meaning a massive or repeated innoculum of eggs. Your peach would not be
able collect such an abundance of eggs from irrigation water or hands.
Also the eggs cannot survive exposure to direct sunlight.
This infection is not uncommon in the United States, in 1976 its
incidence was reported as 2.7%, most infections occur in the South due to
warmer temperatures and high humidity which favor survival and develpment
of the eggs in the soil. In the past incidences of infection in some
areas of the South reached 25%. Most infections occur in children
because they are much more likely to ingest soil then adults. Also
humans can become infected with the dog trichuriid T. vulpis, however it
should be suseptible to the same drugs as T. trichuria.
I cannot find any mention of treatment failures with the common
antiheminthics, so your case is puzzling. Reinfection or
misidentification are what I would be concerned about. There is a
related species of worm found in the Philippines and Thialand which is
much more difficult to treat. It has an egg similar to trichuris which
could be misidentified by the inexperienced.
I hope this information is useful and I hope your friend recovers.
