University of Montana Catalog 2025-2026

Integrative Microbiology B.A.

Microbiology is the study of microorganisms including bacteria, fungi, viruses, and protozoa. The Integrative Microbiology major takes an interdisciplinary approach to the study of microbial structure and function and encourages the integration of microbiology with the study of other disciplines.

General Degree Requirements

To earn a baccalaureate degree, all students must complete successfully, in addition to any other requirements, the University of Montana General Education Requirements. Please refer to the General Education Requirements page for more information. 

Additional requirements for graduation can be found on the Degree/Certificate Requirements for Graduation page

Unless otherwise noted in individual program requirements, a minimum grade point average of 2.00 in all work attempted at the University of Montana-Missoula is required for graduation. Please see the Academic Policies and Procedures page for information on how your GPA is calculated.

Courses taken to satisfy the requirements of a major, minor, or certificate program must be completed with a grade of C- or better unless a higher grade is noted in the program requirements.
