Course Description
This course is a survey of the biology of microorganisms with an emphasis on bacteria. Topics include prokaryotic diversity, bacterial cell structure and metabolism, and microbial reproduction, introductory virology, immunology, epidemiology, public health, and selected topics in medical microbiology. Laboratory activities introduce a wide variety of techniques in microbiology and immunology.

Learning Outcomes
Upon completion of this course, successful students will be able to:
- Describe the range of prokaryotic and eukaryotic organisms that are considered to be microorganisms and explain the historical context of microbiological science.
- Identify and explain the components and cellular structure of bacterial cells.
- Explain the principles of classification and be able to explain the classification of bacteria.
- Explain the process of bacterial cell division, and relate it to the growth of bacterial populations
- Describe the principles involved in the control of bacterial growth.
- Describe the structure of viruses, viral replication and explain the role of viruses in disease.
- Explain the difference between innate and acquired immunity to disease in humans and the effects of humoral and cell-mediated responses.
- Describe the mechanisms of microbial pathogenesis.
- Explain the modes of transmission and mechanisms of infection by human bacterial diseases and strategies for management of transmission and infection in the context of public health.
- Explain the basis of the development of bacterial resistance to antimicrobial agents.
- Demonstrate familiarity and competency with a wide variety of microbiological laboratory techniques including transfer, culture, isolation and identification techniques, growth rates and antibiotic sensitivity.
Means of Assessment
Evaluation will be carried out in accordance with the Douglas College Evaluation Policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on the following:
| Class tests and assignments | 20-30% |
| Laboratory | 20-30% |
| Term exam(s) | 20-40% |
| Final exam | 20-40% |
| Total | 100% |
