Document Summary

Development forms of food-borne : cruzi is not transmitted because you are bitten but because they defecate and then you get infected through there, gondii oocysts are only in the definitive hosts, the cats. Some parasites remain in the apical portion, like cryptosporidium. With entamoeba, most people get diarrhea and dysentery when they get it. With dysentery diarrhea, there is blood in the stool. This parasite also goes to the liver (extra-intestinal parasite). Can effect several million people, and we have it here (not just in developing countries). Several outbreaks are in developing countries as well. This disease can kill people especially if they are hiv positive. Millions of people are infected, and especially when you travel and come back you could experience diarrhea. It could be many of the parasites discussed so far. The best way to diagnose would be to look at the stool under the microscope. Important: when people have diarrhea, stool analysis is always useful.
