MBV9150 – Molecular and Cell 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
  • Be able to design and execute research on symbiotic microbial - host systems


PhD candidates from the University of Oslo should apply for classes and register for examinations through Studentweb.

If a course has limited intake capacity, priority will be given to PhD candidates who follow an individual education plan where this particular course is included. Some national researchers’ schools may have specific rules for ranking applicants for courses with limited intake capacity.

PhD candidates who have been admitted to another higher education institution must apply for a position as a visiting student within a given deadline.

The courses MBV4150 and MBV9150 have common admission. Applicants are ranked by the following criteria:
1. PhD candidates and master students at the MN faculty who have the course as part of the approved curriculum.
2. Other PhD candidates and visiting PhD candidates.
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.


During the colloquia you will be asked to present a short seminar on a subject related to the course topics.

This will count as 50% towards the course evaluation. The other 50% will comprise an written exam.

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