1. Compare and contrast Chagas disease and cysticercosis.
Chagas disease cysticercosis Parasite (Worm or protozoan) protozoan worm
Effects on human host
Fever, swelling around initial infection site, parasites in blood, sometimes asymptomatic, rarely debilitating or life threatening problems can occur.
Formation of larval cysts can occur in the muscles, eyes, brain, and/or spinal cord. Cysts in these areas can lead to other side affects.
How parasite is transmitted.
Contact with insect feces and through the blood. Maybe through ingestion.
Ingestion.
2. True or false Correct the false questions. You are not allowed to correct simply by adding a no, not, etc.
Chagas disease is acquired through the bite of a blood-sucking insect.
False. No it is through the feces of an infected insect vector.
Triatomine bugs are found in the Southern Unites States.
True. They can be, yes, but it is rare.
Cysticercosis is found worldwide.
True
Cysticercosis is spread by eating undercooked pork (Be careful --- This is a tricky question.) GUIDE and http://www.cdc.gov/parasites/cysticercosis/biology.html)
False. The infection with the adult tapeworm is caused by this. You get Cysticercosis is spread when pigs eat the feces of a human with the adult tapeworm and the eggs in the feces enter the pig and hatch. The larva can enter a human from eating undercooked meat of a pig with the larva and later turn in to cysts in the human gut.
Cysticercosis causes damage when adult tapeworms accidentally lodge in organs other than the intestine.
False. The tapeworm only lays the eggs. It does not cause Cysticercosis.
3. Why are the two parasitic diseases studied considered diseases of the poor?
It is likely that the impoverished housing in poor areas allow the parasites to live and also allow animals to be in contact with human feces and humans to be in
