CASE-BASED QUESTIONS 1. Population studies show type O blood is practically extinct in populations from the Ganges River delta in India. Based on this chapter, provide a possible evolutionary explanation for this. 2. Provide a possible explanation for why Koch experienced difficulties in establishing an animal model for cholera. 3. What type of electron microscopy was most likely used to obtain the data about V. cholerae's colonization of copepod external surfaces? Explain your reasoning. 4. We now know the miasma theory is wrong, so how did proper sewage management help reduce cholera cases, if not by reducing the stench? 5. How would you define the symbiotic relationship between copepods and V. cholerae? Explain your definition. 6. How would you describe the biota classification or status of V. cholerae in humans? How about in copepods?

15) What is the natural habitat (reservoir) for Vibrio cholerae? 16) How is Vibrio cholerae usually transmitted to humans? 17) How many cells make an infective dose of Vibrio cholera? Can a single copepod carry an infectious dose? 18) A Vibrio cholerae cell is typically 1-3 µm long. Why is the sari cloth filtration method effective at reducing V. cholera in the water if the pore size of a sari that is folded 4 times is approximately 20 µm? 19) Why do you think that households that did not filter their water were less likely to get cholera if their neighbors did filter their water?
How has modern day epidemiologic studies been influenced by Snow's process to identify the cause of the cholera epidemic?
