Introduction to Microbiology

MICR 271/3.0

Microbes make up a large component of the earth’s total biomass. In addition to pathogens causing significant infectious diseases, a healthy human being carries around approximately 100 trillion “good” bacteria, as well as other microbes. MICR 271provides an introduction to the biology of prokaryotic and eukaryotic microbes, including pathogenic and beneficial bacteria, viruses, fungi, helminthes, and protozoa. An overview of the biological features of these microorganisms and their component parts will highlight their roles in public health and the environment.

Learning Outcomes

After completing MICR 271, students will be able to:

  1. Employ a basic understanding of the biological features of bacteria, viruses, and eukaryotic microbes to transition to higher level microbiology courses.
  2. Analyze information pertaining to a specific organism to evaluate the impact of antibiotic resistance of the microorganism in health, disease or the environment.
  3. Collaboratively demonstrate a working knowledge of microbe characteristics that relate to their survival by working effectively with peers.
  4. Employ effective peer review in a small group setting in order to collaboratively formulate predictions of the success or failure of designed superbugs.
