Further information
The course is conducted in English. The course is completed in a written exam and by reporting laboratory work
The prerequisite for the exam is successful completion of the pathogen work, i.e. the completion of the course requires active participation in the pathogen group work. After the above-mentioned task, the student can take part in a written exam. The microbiological laboratory work (2 ECTS) is part of this course.
The end results in this course is both the written exam and the laboratory report.
