2026-2028 Catalog

Offered at: San Luis Obispo Campus

Microbiology is the study of bacteria, archaea, viruses, fungi, and protists. Microorganisms are ubiquitous in the environment as important contributors to nutrient cycling, and many have symbiotic relationships with other organisms. Species of medical importance impact human and animal health as pathogens associated with infectious diseases. Additionally, microorganisms are critical research tools in fields such as molecular biology and genetics, and are used for large-scale production of many foods, pharmaceuticals, and industrial chemicals. Cal Poly is one of the few public universities in California offering a laboratory-intensive Bachelor of Science degree in Microbiology.

In the junior and senior years, in addition to microbial genetics, majors can take specialized courses in virology, biotechnology, microbial physiology, medical microbiology, immunology, microbial ecology and computation in microbiology.  Students also choose elective courses related to student interests and career goals in close consultation with their faculty advisors.  Graduates may also pursue post-baccalaureate employment in applied areas such as industrial microbiology, food and dairy microbiology, biotechnology, public health, epidemiology, or medical laboratory technology. Students may not double major in Biological Science and Microbiology.

Program Learning Objectives

  1. Explain fundamental concepts and principles in microbiology and general biology (atom to ecosystem).
  2. Demonstrate proficiency in common lab and field techniques for microbiology.
  3. Locate, critically evaluate, and integrate scientific literature findings into the practice of microbiology.
  4. Assess and analyze experimental data with objectivity.
  5. Integrate statistics, math, physical sciences and technology to answer microbiological questions.
  6. Communicate microbiology principles and research findings effectively to diverse audiences.
  7. Relate ethical, social justice or global perspectives to the study and practice of microbiology.

Degree Requirements and Curriculum

In addition to the program requirements listed on this page, students must also satisfy requirements outlined in more detail in the Minimum Requirements for Graduation section of this catalog, including:

  • 40 units of upper-division courses
  • 2.0 GPA
  • Graduation Writing Requirement (GWR)
  • U.S. Cultural Pluralism (USCP)
Note: No Major, Support, or Concentration courses may be selected as credit/no credit. In addition, no more than 12 units of cooperative or internship courses can count towards your degree requirements.
