Caused by flagellated protozoan
Attaches to human intestinal wall
Causes prolonged diarrhea
Carried in feces, streams and lakes

We ingest oocytes that release sporozoites in the small intestine
Causes cholera-like diarrhea for 10-14 days
Lakes, streams, swimming pools

Protozoan
Cell walls are dissolved in intestinal tract and multiple in large intestine
Causes severe dysentery, blood feces
Found in food or drinking water
