Course objectives

This course is designed to give students understanding of basic concepts in microbiology including various microorganisms their physiology, morphology, genetics, ecology, pathogenicity and application used of laboratory methods and techniques in microbiological research.

Course enrolment requirements and entry competences required for the course


Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

Students completing this course should be able to:
- better understanding of the evolutionary relationships between structure, diversity and replication of different groups of microorganisms.
- learn about genetic mechanisms of adaptation of prokaryotic microorganisms in a variety of environmental conditions.
- applied methods of physiological and biochemical tests for the identification of the different groups of microorganisms.
- identify the mechanisms of pathogenicity of microorganisms that cause diseases in humans and animals as well as the mechanisms used by the hosts to defend themselves against pathogens.
- determine the number of microorganisms in the sample and calculate the growth of microorganisms in controlled laboratory conditions.

Grading and evaluating student work in class and at the final exam

The final grade of the student is compiled from the combination of lecture, seminar, laboratory. Final course grade will be based on: Mid‐term exam 30%; End of term exam 35%; Seminar 10%; Lab course 15%. Course grade will be based upon a percentage of total points obtained using the following scale: <60% insufficient; 60-70% sufficient (2); 70-80% good (3); 80-90% very good (4); 90-100% excellent (5).

Quality assurance methods that ensure the acquisition of exit competences

Quality assurance will be performed at three levels:
(1) University Level;
(2) Faculty Level by Quality Control Committee;
(3) Lecturer’s Level.
