Objective

To provide knowledge of the structure, properties, pathogenicity factors of bacteria, viruses, fungi and parasites and their role in the development of infections. To provide knowledge of the human microbiome, its role in normality and pathology. To provide information on the cultivation of aerobic and anaerobic bacteria, methods of isolation of pure cultures and methods of identification of bacteria. Provide knowledge of groups of antibiotics, their mechanisms of action, bacterial resistance mechanisms, methods of detecting antibacterial susceptibility. Present disinfection and sterilisation methods and their role in the prevention of nosocomial infections. To know the innate resistance of the organism, mechanisms of resistance.To provide knowledge of the body's immune system, immune cells, cytokines, signalling and cell activation. Types and mechanisms of the immune response. The importance of humoral and cellular immunity in bacterial, viral, fungal and parasitic infections, immunoglobulins, their classes and importance. Knowledge of immunopathology, hypersensitivity reactions and their mechanisms. Knowledge of immunisation, types of vaccines, mechanisms of their action. Knowledge of serodiagnostics, types of serological reactions, molecular diagnostic methods, their working principles.

Knowledge of clinically relevant infectious diseases caused by bacteria, viruses, fungi and parasites, the role of pathogens in their pathogenesis. Knowledge of diagnostic methods in clinical bacteriology, virology, mycology and parasitology, diagnostic algorithms, principles of non-specific and specific prevention, principles of antibacterial therapy selection.

Preliminary Knowledge

Molecular and cellular biology, human anatomy, histology, medical genetics, biochemistry and human physiology.

Learning Outcomes

Knowledge

1.At the end of the course part 1 students will be able to characterise the properties of bacteria, viruses, fungi, their morphology, pathogenicity factors, their role in the development of infectious diseases and the interaction process with the role of macroorganisms, human body and environmental microbiota. Students will gain knowledge of groups of antibiotics, their mechanisms of action, mechanisms of bacterial resistance. Students will learn about protective immunity mechanisms of the human body, types and significance of immune response, immunisation and immunisation mechanisms, immunopathology, hypersensitivity reactions.

2.Upon completion of the programme part 2, students will have acquired knowledge of pathogenicity of bacteria, viruses, fungi and parasites, their role in the pathogenesis of infectious diseases, as well as information on principles of bacteriological, serological and molecular diagnostics, algorithms of diagnostics of infectious diseases, specific and non-specific prevention methods, principles of antibacterial therapy.

Skills

1.On completion of the part 1 the student will be able to: • microscopically examine patient material, inoculate using appropriate media • isolate and identify pure cultures of bacteria, • assess sensitivity to antibiotics • use sterilisation methods • use disinfection methods • use bacteriological, serological and molecular diagnostic methods.

2.On completion of the course part 2, the student will be able to: • Collect patient material, evaluate the importance of sample volume by assessing the effect of sampling time on the result; • Transport and examine patient material; • Isolate and identify pure cultures of bacteria, assess susceptibility to antibiotics; • Practical application of bacterial, viral, fungal and parasitic diagnostic methods (including bacteriological, serological and molecular diagnostic methods), interpretation of tests; • Dealing with situations involving cases of diseases caused by different bacteria, viruses, fungi and parasites; • Apply micro-organism diagnostic methods and algorithms when dealing with situations.

Competences

1.By combining theoretical knowledge and practical skills, students will be able to understand the role of viruses, bacteria, fungi and parasites in the development of infectious diseases; understand the role of the pathogen in the pathogenesis of disease; to understand the mechanisms and role of immune response; know the pathogenesis, symptoms and specific and non-specific prevention of major infections; and use knowledge of bacteriological, serological and molecular methods for their diagnosis. Students will be able to explain how the pathogenesis of infections affects the selection of specimens to be tested and the interpretation of tests. They will be able to solve clinical cases involving information about different pathogens.

Assessment

1.

Individual work

-
-

As part of Part 1 of the course, students are required to prepare 7 MCQ tests based on the topics covered in the practical sessions of the course. Students can use the resources available on e-studies, including study materials, videos on practical tasks and skills, materials on the immune response and video lectures on specific topics.

2.

Individual work

-
-

Each student must prepare 4 presentations independently during the course part 2- diagnostic diagrams of infectious disease, according to the course topics, using materials prepared by the Department: patient clinical cases and situation tasks, acquisition of clinical material, proper transport to the laboratory, diagnostic circuits, pathogenic agent identification methods. During the practical class, the student presents his/her prepared clinical case on the relevant topic, presents identification methods for diagnostic algorithms and pathogenic agents. During the practical class, the independent work prepared by the student is evaluated.

In order to evaluate the quality of the study course as a whole, the student must complete the study course evaluation questionnaire on the student portal.

Examination

Test

-
10 points

• Regular attendance at lectures, demonstration lectures and practical classes, active participation in practical classes. • Successful completion of mid-semester examinations. • Successful completion of 2 colloquia including a test of theoretical knowledge and skills.• If these requirements are met, students will successfully complete the Part 1 of the course. • At the end of Part 2 of the course, successful completion of 4 colloquia, attendance of practical classes and fulfilment of practical work requirements, a cumulative assessment will be made taking into account all the above assessment criteria for Part 1 and Part 2 of the course. The average grade of the colloquia will count for 80%, the average grade of the regular tests will count for 20%, and the resulting grade will be multiplied by the attendance rate of the demo lectures and practical classes. • If a student scores at least 4 points in the cumulative assessment, this will be the same as the final assessment. If the cumulative assessment is below 4 points, the student must take the final examination of the course - an oral examination with the Teaching Staff Commission. The examination includes a test of theoretical knowledge and questions on the subjects covered in the practical classes.
