week 1Koch’s Postulates (graded)As a skilled microbiologist, you have been calle

week 1Koch’s Postulates (graded)As a skilled microbiologist, you have been called to Farmer McDonald’s farm to investigate an outbreak of sores on the udders of his cows. Your first task is to determine whether the causative agent of the sores is a microbe. Explain how you will you use Koch’s postulates to accomplish this.Characteristics of Prokaryotic and Eukaryotic Cells (graded)The endosymbiotic theory proposes an explanation of the origin of mitochondria, chloroplasts, and eukaryotic cells. Discuss the evidence for this theory. Are you convinced?week 2Microscopy (graded)What microscope would you use to study the complex interactions of microorganisms in a biofilm? Why is this the best choice? What would be your second choice?Culturing Microorganisms (graded)Many microorganisms are very fastidious and have never been cultured in a lab. Class, let’s discuss the nutritional requirements of bacteria and the techniques for culturing them in a lab.week 3Microbial Metabolism (graded)All living cells are capable of metabolism. Many metabolic pathways are amphibolic. Class, let’s discuss the many different ways cells regulate their metabolic pathways to maximize efficiency.Characteristics of Eukaryotic and Viral Pathogens (graded)Some people argue that viruses cannot be considered alive. Do you agree with this statement? Defend your answer.week 4Choosing an Antimicrobial Technique (graded)You be the expert: Imagine you are a teaching a class on controlling microbial growth in the environment. To test your students, you will present them with a scenario including a site and some probable microbes present. They must design a strategy to eliminate harmful microbes from the area.In this discussion, each student (at a minimum) should present a scenario for analysis by his or her classmates, propose an answer to another classmate’s scenario, and respond to all classmates who attempt to address the scenario. Be as creative as you can!Antibiotic Resistance (graded)Discuss why MRSA presents a major public health issue. Propose some ways to limit or remove this threat.week 5Innate Immunity (graded)Individuals with third-degree burns are particularly vulnerable to infection. Can you speculate about why this is so?Adaptive Immunity (graded)Your friend Bruce calls in a panic. He has just come from the doctor and been diagnosed with a bacterial infection. The doctor told him not to worry; his B cells will take care of it in no time! Knowing that you are studying the immune response, he is calling to ask you to explain this statement. Is the doctor correct? Is there more to the story?wekek 6Epidemiology (graded)Please insert your first graded discussion question here.Case study: Over 30 children younger than 3 years of age developed gastroenteritis after visiting a local water park. These cases represented 44% of the park visitors in this age group on the day in question. Older individuals were not affected. The causative agent was determined to be a member of the bacterial genus Shigella. The disease resulted from oral transmission to the children.Based only on the information given, can you classify this outbreak as an epidemic? Why or why not? If you were an epidemiologist, how would you go about determining which pools in the water park were contaminated?Make the Diagnosis: Bacteria (graded)This week’s readings encompass a wide variety of diseases associated with various organ systems. Using the information in your text (and any other resources you choose), give your patient one of these diseases from the organ system discussed this week, and present the history and symptoms to the class. Be creative! Be sure to offer enough information to make an educated guess, but try not to give it away too soon! Each student should present a case. Be sure to let those who respond to your case know whether they correctly diagnosed the patient. In some cases, you might offer new test results midweek if the class is stumped!week 7Microbial Antagonism (graded)Class, we discussed the term microbial antagonism in Week 2 and have come across many examples of how it helps us against pathogenic microorganisms. Let’s discuss the role of the intestinal microbiota in the maintenance of health and the many opportunistic pathogens that cause disease when the delicate balance of normal microbiota in this region of the body is disturbed.As a skilled microbiologist, you have been called to Farmer McDonald’s farm to investigate an outbreak of sores on the udders of his cows.
