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?

Protozoan Case Studies CASE 1 A 22 year old woman was admitted to the emergency department at 3:00 a.m. complaining of burning during urination and severe vaginal itching. The physician ordered a routine urinalysis and a vaginal swab for microscopic examination. The technologist observed many motile organisms measuring approximately 12 um in diameter in both the urine and vaginal wet mount preparations. The following is what was observed in the wet mount Questions 1) What is the likely genus and species of this organism? 2) Besides size and shape, what is the hallmark diagnostic feature, observable under the microscope? 3) How is this infection acquired? 4) What is the life cycle of this organism? 5) What symptoms are seen in men that are infected with this organism? Does this contribute to the spread of disease? If so, how? 6) What are the S&S of infection in women? CASE 2

What are the different types of microorganisms and what are the defining characteristics of them? 1. What were the major contributions to microbiology by the following scientists and have a general idea (e.g. which century) of when they occurred: A. van Leeuwenhoek B. Pasteur C. Linnaeus How have the phylogenetic trees changed since Linnaeus? What is the correct naming of an organism using binomial nomenclature? D. Woese What sequence allowed Woese to make his significant discovery? How has this fundamentally changed how we think about species? E. Redi What does spontaneous generation mean? What is the purpose of the open container in his experiment? F. Pasteur Why was the bend in the swan neck flask important? What was the purpose of the flask that had the neck broken off? G. Semmelweis H. Snow What field did Snow develop through his work? I. Lister J. Koch What are the 4 postulates in the correct order? K. Ehrlich L. Fleming M. Jenner

Mini-Case #2 – Tyesha's Story: Cholera Video Questions 1. Many different types of micro-organisms can disrupt the function of the gastrointestinal tract. V. cholera is a good example, causing short acute bouts of dizziness, disorientation, and diahrrea that, if untreated, can even be fatal. The cholera organism itself is a(n) ... a) bacterium. b) fungus. c) virus. d) parasite. e) worm. f ) tick. 2. How does V. cholera most frequently gain entry to the body? a) The bite of a mosquito or sand fly. b) Living in a household with another person who has cholera. c) Drinking of water that has not been properly purified of contaminating feces. d) This type of disease is usually nosocomial, i.e., of hospital origin. e) All of the above are likely. f ) Primary concerns are items a, b, and c. 3. The gastrointestinal structure whose function is targeted by V. cholera is a) mechanical disruption of food in the oral cavity. b) peristalsis in the esophagus. c) hydrochloride ion secretion by the parietal cells of the stomach. d) iron uptake in the duodenum. e) chloride ion transport system and fluid uptake in the jejunum. f ) vitamin uptake by receptors in the ileum.
