BIOL 323– MICROBIOLOGY FALL 2007 Instructor: Dr. Holly Pinkart Text: Brock Biology of Microorganisms, 11th Ed Lab manual: On Blackboard E-mail: PinkartH@cwu.edu Phone: (509) 963-2710 Office Location: SCI 236D Office Hours: M 2:00-4:00, W 10:00-12:00, or by appointment Course objectives: This is a general course in microbiology. The emphasis is on prokaryotic organisms, with other microbes covered more generally. Students will learn about microbial cell structure, physiology and genetics. These topics will provide a basis for understanding how to control microbial growth, various aspects of metabolism, infectious disease, and microbial ecology. The laboratory component of the course is designed enhance understanding of microbiology through study of microbial cell structure and metabolism. Prerequisites: Cell Biology BIOL 220, and Chemistry through CHEM 113 or CHEM 182/182.1. My Expectations of You: I expect that you will have had the proper prerequisites for this course. This means that you are familiar with basic chemistry (Chapter 3) and the structure of eukaryotic cells (Chapter 4.5-4.7, 14.1-14.5). You will also be familiar with the concept of aerobic cellular respiration; glycolysis, citric acid (aka TCA, Krebs) cycle and the electron transport system in mitochondria. This is a course designed for biology and biochemistry majors; PRE-NURSING AND NUTRITION MAJORS ARE GENERALLY MORE COMFORTABLE IN BIOL 322. I expect academic honesty in all matters (see Appendix B in CWU catalog). Cheating and/or plagiarism will not be tolerated. The following is an outline for the quarter; schedule is subject to change.

Otherwise, if you miss an exam, you must take a comprehensive exam at the end of the quarter to make it up. This applies to one exam only. NO EXCEPTIONS. Quizzes will be posted on BlackBoard on Thursday, and remain available until 11:50 pm Sunday night.

I will post my Powerpoint presentations there so you will have access to those as well as other course materials. Read the corresponding text chapters prior to class so you can follow course discussions. 2) Please read the lab manual handouts prior to the corresponding lab period. Rewrite your notes soon after class – this will allow you to identify confusing points so you can ask questions. 3) Don’t use your cell phone in lab or during lectures. If you must have them on, set them to vibrate (I understand you may have kids, family issues, etc). Step outside the classroom if it is an emergency. 4) Feel free to ask questions at any time. And please use my office hours! If you cannot make it during my office hours, please make an appointment. 5) Students with disabilities who wish to set up academic adjustments in this class should give me a copy of their “Confirmation of Eligibility for Academic Adjustments” from the Disability Support Services Office as soon as possible so we can meet to discuss how the approved adjustments will be implemented in this class. Students with disabilities without this form should contact the Disability Support Services Office, Bouillon 205 or dssrecept@cwu.edu or 963-2171 ASAP. 6) No, there is no extra credit (except for what is offered on exams). Concentrate on doing well the work that is required, and you won’t need to do extra work to make up for poor performance. COURSE OUTCOMES Microbiological Knowledge Upon completion of this course, students will be able to discuss and explain concepts relating to 3 major themes in microbiology. Theme 1: Microbial cell biology Microbial cellular structure and function Microbial growth and reproduction Cellular energy production and metabolism Structure and reproduction of infectious particles (viruses and prions) Theme 2: Microbial genetics, evolution and diversity Inheritance of genetic information Information flow within a cell Exchange and acquisition of genetic information Causes, consequences and uses of mutations Evolution of microbial genetic and physiological diversity Microbial ecology Theme 3: Interactions and impact of microorganisms and humans Microbial-human relationships Microbial pathogenicity mechanisms Disease transmission Antibiotics and chemotherapy Genetic engineering Biotechnology Laboratory Skills A student successfully completing this course will demonstrate ability to 1. 2. 3.
