MBV4150 – Molecular biology of microbes - host interactions

Schedule, syllabus and examination date

Choose semester

Course content

The course covers the themes and diversities of plant and animal associations with microbes that involve beneficial relationships (symbiosis). Emphasis will be placed on the molecular mechanisms acting within both the microbe and host that create, shape and define the symbiotic state. The course provides insight into the critical (but often unappreciated) role of both exo- and endosymbionts to evolutionary processes.

Learning outcome

After completing the course we expect your competence to include the following:

  • Have a deep understanding of symbiotic microbial - host interactions at the molecular and ecological levels
  • Be able to critically analyze state of the art literature relating to microbial symbiosis
  • Be able to understand the crucial role of microbial symbiosis as a driving element of evolution
  • Be able to recognize the commonalities and differences defining symbiotic and pathogenic microbial - host interactions


Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures.

PhD students must apply for the course MBV9150 - Molecular and cell biology of microbes - host interactions

The courses MBV4150 and MBV9150 have common admission. Applicants are ranked by the following criteria:
1. PhD students and master students at the MN faculty who have the course as part of the approved curriculum.
2. Other PhD students and visiting PhD students.
3. Students with admission to single courses on master’s level and exchange students
4. Applicants are ranked by credits in each group; all applicants within 1st rank before applicants in 2nd etc. If admission is limited to a fixed number of participants, admission will be decided by drawing lots for students who are ranked equally


The course lasts five weeks every spring semester and the teaching methods will consist of 20 hours of lectures and 20 hours of seminars including student presentations.


The presentation from the seminars must be approved before the final written exam one week after the end of the course.

(Optional oral exam depending on the number of participants.)
