Course abstract

Basics of the theory of pathogenesis of infection in a susceptible macroorganism caused by extracellular, optional intracellular, obligatory cellular bacteria, clinical signs and diagnostic methods of caused diseases. Students have to acquire laboratory methods of identification of bacteria.

Learning outcomes and their assessment

Knowledge of the morphology, biochemical characteristics, growth and general bacteriological diagnosis of animal infectious agents. Knowledge about the pathogenesis of infection in a susceptible macroorganism, its clinical manifestation. 4 tests
Skills: to independently diagnose in a laboratory the fungal pathogens as infectious agents, to analyze and interpret the results. Practicals
Competence to evaluate laboratory results obtained in virology and mycology, to be able to explain them to the sample sender. KEGA work.

Requirements for awarding credit points

Attendance for lectures is not compulsary. Attendace for practical classes of at least 90% is required.
Students are required to PASS four theoretical tests and one clinical and epidemiological case analysis work (KEGA).
Failed theoretical tests are required to be retaken until the next test.
Students are required to carry out any missed practical classes in two weeks time.
Failure to meet the two week deadline constitutes an additional theoretical assignment on the specific topic.
Failure to PASS all assignments and overdue assignments of the study course in the deadline of an academic year constitutes retaking all assignments and/or tests.
Final test – written exam with a mark
A student can take an exam in session if all the tests and KEGA work have been completed to the beginning of the individual study and examination period (session).

Description of the organization and tasks of students’ independent work

Literature, lecture and practical work material studies, analysis of practical work results.
Students compiled a microbiological investigation plan for isolating and identifying conditionally pathogenic bacteria from the specimen.
Interpret the information in submission form about the sample. Compiles a plan of action to be implemented, and repeated the skills required by completing the protocol.

Criteria for Evaluating Learning Outcomes

Students' knowledge and skills are assessed in accordance with the procedures specified in the tasks of the practical works.
To take the exam, all tests must be successfully completed.
All tests and answers of exam are evaluated in accordance with the criteria of the 10-point system scale indicated in the LLU Study Regulations.
The exam is organized in written form.
