These
worms affect only humans and lodge in the small intestine.
They
produce eggs, which pass into stool and then soil.
Larva
will infect people similar to hook worms as they will penetrate
skin and then migrate from the lungs to the intestine.
It
takes years for the worm to mature.
Sometimes
there is a rash at the skin entry and a wandering rash as
they migrate in the skin.
They
also cause cough, wheezing, and abdominal complaints.
They
are diagnosed as stool analysis and treated with anti-worm
medications.
