BIOS9140 – Infection Biology of Microbial Symbiosis

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 endo-symbionts to evolutionary processes.

Learning outcome

  • 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.


The deadline for registration for autumn 2019 is October 11th. Please contact Torill Rørtveit for admission to the course. PhD candidates who are admitted to other education institutions than UiO must at the same time apply for visiting PhD status.
