1. Amoebic dysentery 2. Malaria 3. African sleeping sickness 4. Chagas disease

Identify and state the route of transmission (in other words how we get infected) PART 1: 1. Balantidium coli trophozoites and cyst 2. Cryptosporidium parvum oocyst 3. Entamoeba histolytica trophozoites and cyst 4. Plasmodium trophozoites

1. Fecal-oral. Consume cyst? 2. Fecal-oral, was in a lot of water. 3. Ingest cysts in contaminated food or water. 4. Bite from mosquito from salivary glands.

Identify and state the route of transmission (in other words how we get infected) 1. Ascaris lumbricoides ova 2. Enterobius vermicularis ova 3. Necator americanus ova 4. Trichinella spiralis larvae

1. Fecal-oral. Pooped out, ova develops into infectious stage in soil, gets swallowed. 2. Fecal-oral. Ovum sticky, laid in the anus and adhere there. Usual infection from hand-to-mouth (scratching the butt or handling contaminated stuff) 3. Penetrate skin of foot. Hookworm ova passed in feces, hatch into larvae in soil. Infective larvae penetrate foot and enter circulation. 4. In muscle tissue. Consumption of raw or insufficiently cooked bork or bear meat containing encysted larvae.

5. Fecal-oral. (usually through drinking water.) Wildlife deposit cysts in streams, parasite commonly found in all sorts of domestic animals too. 6. Ingestion through undercooked, contaminated meat (pork, lamb, and venison). ALSO FECAL-ORAL through infected cat feces. Cat is definitive host. 7. Sexually transmitted. 8.
