Department Overview

K-335A Health Sciences

Microbiology is a natural science that deals with microorganisms such as bacteria, fungi, protozoa, algae, and viruses. It is concerned with the nature and properties of these organisms, their effects on humans and the environment, and how they can be exploited to provide useful products.

Undergraduate Program

K-335A Health Sciences, Box 357242
(206) 543-2572

The Department of Microbiology offers the following programs of study:

  • The Bachelor of Science degree with a major in microbiology
  • A minor in microbiology

Bachelor of Science

Suggested First- and Second-Year Courses: PHYS 114, PHYS 115, PHYS 116, or PHYS 121, PHYS 122, PHYS 123; one of the following: MATH 112, MATH 124, MATH 144, Q SCI 381, or STAT 311.

MICROM 410, the first microbiology course for majors, is taken after completion of BIOL 200 and organic chemistry (CHEM 223 or CHEM 237). To graduate in four years, a student must complete introductory biology and organic chemistry before autumn quarter of the junior year.

MICROM 101, MICROM 301, and MICROM 302, offered to non-majors, serve as introductory courses, but cannot be used to fulfill graduation requirements for a major in microbiology. MICROM 301 is a prerequisite for students applying to nursing, physical therapy, or dental school.

  10. Transfer students must complete at least 20 of the required and elective microbiology credits through the UW.

Continuation Policy

All students must make satisfactory academic progress in the major. Failure to do so results in probation, which can lead to dismissal from the major. For the complete continuation policy, contact the departmental adviser or refer to the department website.


Minor Requirements: 29 credits as follows:

  1. 14 credits to include BIOL 200; one of CHEM 152, CHEM 155, CHEM 162, or CHEM 165; one of CHEM 223, CHEM 237, or CHEM 355.
  2. 15 credits from the following: MICROM 410; one from MICROM 302, MICROM 402, MICROM 431, or MICROM 443; and approved 400-level, graded microbiology courses to reach 29 credits. See adviser for approved list.
  3. Minimum cumulative 2.00 GPA for all courses counted toward the minor

Student Outcomes and Opportunities

  • Learning Objectives and Expected Outcomes: The department's objective is to provide a major with the best instruction possible in broad areas of microbiology so students qualify for a wide variety of positions with a terminal BS degree or qualify to pursue advanced degrees in graduate or professional schools.

    Microbiology offers students an excellent education in the biology of microorganisms, namely bacteria, fungi, protozoa, and viruses. Through learning about the biology of these microorganisms and viruses, students more fully understand the pivotal position they occupy in establishing and maintaining our biosphere, their effects on human, animal, and plant life, and how the biological properties of certain microbes are exploited for certain purposes. Microorganisms are important in drinking water, wastewater and sewage treatment, production and spoilage of foods, production of antibiotics, bioremediation of toxic compounds, and genetic engineering of organisms having unique characteristics. Students gain insight into strategies used by microorganisms and viruses to cause disease and the mechanisms used by their host to defend themselves.

    Graduates have found research positions in biotechnology and pharmaceutical companies, as well as in state and government positions hiring microbiologists. Students interested in a health profession or graduate program benefit from this program.

  • Instructional and Research Facilities: Microbiology courses are taught using state-of-the-art facilities in the teaching wing of the Health Sciences building. Research labs are located in the Health Sciences, Fred Hutchinson Cancer Research Center, NW Regional Primate Research Center, and UW Rosen building.
  • Honors Options Available: With College Honors (Completion of Honors Core Curriculum and Departmental Honors); With Honors (Completion of Departmental Honors requirements in the major). See adviser for requirements.
  • Research, Internships, and Service Learning: MICROM 499, undergraduate laboratory research, is offered for credit. See adviser for details.
  • Department Scholarships: The department offers four awards each year. More information is available at the department's website.
  • Student Organizations/Associations: The Microphiles Club is open to all students. The club sponsors field trips to local biotech companies, speakers on topics such as research and career opportunities, graduate school, and peer teaching.
