For each Unit, I will post the objectives with additional notes at the top of each Unit section. I’ll have a few notes for the objectives to help students ensure they are covering the full scope of the objective while preparing for exams. Unit 1: Introduction to Microbiology Objectives 1. Identify the contributions of the early contributors to the science of microbiology. Include the development of the “Germ Theory of Disease” and Koch’s Postulates. It will be a good idea have a general understanding of the question that each of the early contributors was trying to answer with their work and also how they went about addressing their question, i.e. experimental setups. NOTE: Koch’s Postulates are in Chapter 13 of our text. 2. Describe Whittaker's five-kingdom classification system. Mainly for this objective, you need to know what the five kingdoms are and what type of organisms are found in each kingdom. Keep in mind that we’re getting away from the five kingdom system and focus more on domains and then kingdoms within those domains. For example, Kingdom Monera is actually two domains: Bacteria and Archaea, and the remaining four kingdoms are all part of domain Eukarya. 2a. Properly write scientific names This objective is being pulled in from the Lab Objectives. In this course, you will always be expected to always write/format scientific names in the proper form always, both in “lecture” and lab, so it is appropriate to cover this early in “lecture.” 3. Discuss the basic differences among and uses for the light, dark-field, phase-contrast, fluorescence, and electron microscope. You will need to understand the basics of how light and electron microscopes work and how each type is different from the other types. You will need to know which type of microscope would be best to use in various scenarios. It would be a good idea to think about whether or not specimen might need to be dead in order to be viewed on a particular type of microscope. For example, any analysis with an electron microscope would involve dead specimen. 4. Identify and describe the function of prokaryotic cell structures. Pretty straight forward here. Be able to identify without a word bank and be sure you’re clear about the functions of each structure and any detailed information included in the slides, e.g. the information about flagella and chemotaxis, the differences/similarities of the Gram negative and Gram positive envelopes, etc. 4b. Illustrate the fundamental cellular shapes and arrangements of bacteria. Another import from lab objectives that fits appropriately in Unit 1. You will be expected to recognize shape and arrangement outside of lab, so it is appropriate to cover this topic in “lecture.” 4c. Explain the characteristics used to classify bacteria according to Bergey’s manual. Last import from lab objectives. We actually don’t cover this much in lab, and you’ll only be responsible for the information on the slides regarding Bergey’s manual on the Unit 1 Exam. You will not be expected to know the different categories/classifications/volumes of Bergey’s manual. 5. Classify bacteria into three principal groups based on temperature requirements. Psychrophiles, Mesophiles, Thermophiles and also add those that prefer temperatures hotter than the thermophiles. 6. Categorize the various nutritional patterns among organisms.  Heterotrophs, Autotrophs (both chemo- and photo-autotrophs). What kind of nutrients to bacteria need? Where do they get them? 7. Classify bacteria into four principal groups based on oxygen requirements. There are four different categories for this one. Be sure you discern the difference between the aerotolerants and facultatives. Additionally, it is important to know how we determine these requirements using thioglycolate broth. 8. Describe binary fission and a typical growth curve in bacteria, including the factors that influence the growth phases. There are four parts to bacterial growth curves – be familiar with what happens in each phase/part. Also, be familiar with the processes/”stages” that occur during binary fission. 9. Discuss bioterrorism with considerations of various agents, delivery systems and health responses. You only need to review the slides that pertain to this when studying for the exam. You might have to do a little more than that for the homework, but you’ll only be asked about what’s on the slides on the exam. Unit 1 Reading Assignment: Chapters 1, 3, 4 & 7
