After an egg of H. nana has been ingested, an oncosphere hatches from the egg and penetrates the intestinal villi, where it develops into a cerocyst; the cerocyst reenters the cavity of the size intestine and develops into an animate being worm. Eggs are liberated from the distal segments of the animate being worm, which lives for about 1 year. The eggs may campaign internal reinfection. Lighting transmission is usually asymptomatic; diarrhea and abdominal pain may accompany histrion corruption. Diagnosis is made by physical object eggs in feces. Therapy consists of praziquantel (25 mg/kg given once); this use of praziquantel is currently considered investigational. An alternative investigational therapy is nitazoxanide (500 mg p.o. daily for 3 days).
