Microbiology (BIO-255E/BIO-255LE)

Microbiology Lecture (BIO-255E) is a self-paced, online biology course that offers you an introduction to key principles in microbiology. You'll gain a functional understanding of microscopic organisms (microorganisms), their role in disease and the environment, and our defenses against infections.

Microbiology Lab (BIO-255LE) is available in two formats (self-paced, online lab course or semester-based, on-campus lab course). In this lab, you will learn proper laboratory techniques, such as how to use a microscope, prevent the spread of bacteria, and collect and manage microbial cultures. The semester-based, on-campus course is currently unavailable.

After completing the courses above, you'll be well-prepared to pursue a degree in fields such as health science, pre-medicine, chemistry and biology, or pharmacy.
