Microbiology Courses for Undergraduates
Microbiology majors must have a minimum of 36 credits in upper division microbiology with a 2.0 minimum GPA. All students must take MB 302, 303, 310, 311, 312 and MB 490.
After completing these required courses, 20 credits of 400-level microbiology classes are required and two credits must be from a 400-level laboratory class. BOT 350 (Introduction to Plant Pathology) and BOT 461 (Mycology) count as 400-level MB classes. Research (MB 401), Thesis (MB 403), Reading and Conference (MB 405), and Internship (MB 410) can count for 3 credits; and Teaching Assistantship (MB 406) can be used for 3 additional credits. Speak with an advisor prior to registering for these courses. Any additional credits in these areas will count as general electives. All required courses must be taken for a grade. See your advisor for further details.

Microbiology Minor Requirements
All Microbiology minors are required to take MB 302, MB 303, MB 310, MB 311 and MB 312. The remaining 13 required hours must come from 400-level microbiology courses, including one 400-level laboratory course. Not more than 3 of these credit hours can come from MB 401. Other blanket courses cannot be used to satisfy the minor requirement.
University Baccalaureate Core Requirements
The Baccalaureate Core (Bacc Core) Curriculum represents what the OSU faculty believes is the foundation for students' further understanding of the modern world. The Bacc Core requires students to think critically and creatively, and to synthesize ideas and information when evaluating major societal issues and draws from science and the humanities. More importantly, the Bacc Core promotes understanding of relationships among disciplines in order to increase students' capacities as ethical citizens.
