B.S. Microbiology

InoculationMicrobiology is a fundamental biological science centered on how microbes affect human and animal health and our environment. The discipline covers a wide spectrum of specialized areas, including: pathogenic microbiology and immunology, microbial genetics and phage, virology, food and dairy microbiology, microbial ecology, bacterial physiology, epidemiology, and animal disease.

Microbiologists have made some of the most important scientific discoveries over the last century, and in recent years, the field of microbiology has impacted virtually all other scientific disciplines. For this reason, students who choose to major in microbiology often minor in biotechnology or food safety; and students who choose to major in other fields may find it beneficial to minor in microbiology.

To graduate with a microbiology major from NDSU, students must achieve a 2.50 cumulative grade point average and a minimum grade of “C” in core and elective microbiology courses.

Below you will find a list of core and elective microbiology courses for the undergraduate micro major. Each entry includes a short description of the course, including, the instructor’s name, when the course is offered, and the most recent syllabus for that course.
