Collaborate with your peers to come up with answers to these case studies. Use information from your textbook on the following list of diseases to help answer the questions. a. giardiasis. b. cryptosporidiosis. c. toxoplasmosis d. malaria. e. pinworm infestations. f. trichomoniasis g. pork tapeworm infection (Taenia solium) h. yeast infection (Candidas albicansis)Case Study 1 1. In Egypt, the Christian minority makes a living gathering up the city garbage and feeding it to their hogs, who inhabit the lower court yards of their homes. They also eat pork as part of their diet. Explain how this custom can result in humans becoming the definitive host for the tapeworm, Taenia solium. Case Study 2 2. The Boy Scout troop made their annual trek to lake Wobegon where they camped for 4 nights and practiced canoeing and other water sports. A week later, almost the entire troop came down with severe cramping and frothy mucus diarrhea that smells like rotten eggs. Only the members of the troop that stayed home from the campout were not affected. What was it?3. Ellen and Steve live in a bungalow with their three cats and a dog. They are eagerly looking forward to adding a baby to their active household. The couple became concerned when their obstetrician asked to consult with them both, following a routine prenatal examination. The physician explained that a blood sample drawn from Ellen, 2 months pregnant, showed elevated IgM antibody levels to the protozoan Toxoplasmosis gondii. Why should they be concerned? Case Study 4 4. Ms. Jones can't understand why several of the children in the kindergarten class where she is substitute teaching are always so sleepy. Most of them have no interest in a snack and are irritable; she often catches them scratching themselves in inappropriate places. She decides that this is not a grade school where she wants to substitute teach again. It is just too much work and the children are just too difficult. She tells the principal that she cannot teach beyond the end of the week since she has another commitment at a different school across town. When she reaches the new school the next week, she sees the same behavior in several students in this classroom. Luckily, the school nurse is visiting and they have lunch together. Ms. Jones confides in the nurse that she may not be cut out to teach kindergarten. The nurse laughed and said she thought she knew what the problem might be since something had been "going around" at the local schools. The nurse offers to stop by to observe the children and then write a letter home to their parents. Why did the nurse want to stop by? What do you think the nurse will tell the parents to do in the letter?.
