| Course abstract | |
| During this study course students learn about the structure, morphological and biological properties of microscopic fungi and viruses, their reproduction or replication and classification. Students learn about the pathogenesis and clinical signs of diseases caused by microscopic fungi and viruses. Students learn the general laboratory methods for the identification of microscopic fungi and viruses. In the molecular biology section, students will learn about the components and structure of genetic material, history of molecular biology, main processes of molecular biology and the main methods and applications of molecular biology. | |
| Learning outcomes and their assessment | |
| Knowledge of the morphology, biochemical properties, growth requirements and general laboratory methods in diagnosing microscopic fungi and viruses. Knowledge about the pathogenesis and clinical signs of fungal and viral diseases in different animal species. Knowledge of types, components and structure of genetic material. An understanding of the basic processes and methods of molecular biology. Basic knowledge of main molecular biology laboratory methods and applications.
Skills: to independently diagnose microscopic fungi in a laboratory, to recognize fungal and viral diseases in different animal species. The ability to choose and take the proper sample for viral investigation. Ability to apply the acquired knowledge about the genome and the processes of realization of genetic information in the evaluation of the impact of mutations. Competence to evaluate the obtained laboratory results in case of viral or fungal disease, to be able to explain them to the sample sender. The ability to relate specific stages of cell development or processes within the cells to molecular biology processes. Acquired knowledge is assessed with 3 theoretical tests. |

| Requirements for awarding credit points | |
| Lecture attendance is not mandatory.
Laboratory work attendance is mandatory. Each student is allowed to miss 3 laboratory works in a semester (including two excused absences). Missing more than 3 laboratory works constitutes retaking the whole study course. Students are required to carry out any missed practical works in two weeks time. Failure to meet the two week deadline constitutes an additional theoretical assignment on the specific topic. Students are required to pass three theoretical tests. Failed theoretical tests are required to be retaken until the next test. Each theoretical test can be taken three times – two times in a written form, and the third time with a committee. Not passing a theoretical test with the third time constitutes retaking the whole study course. The student is not allowed to partake in the final exam, if the student fails to pass all theoretical tests of the study course at least one week before the final exam. Failure to pass all theoretical tests of the study course within the period of individual studies and examinations constitutes retaking of the whole study course. Final test – written exam with a grade. |

| Description of the organization and tasks of students’ independent work | |
| Studies of literature, lecture and practical work materials, analysis of practical work results. | |
| Criteria for Evaluating Learning Outcomes | |
| Students' knowledge and skills are assessed in accordance with the procedures specified in the tasks of the practical works.
The study course tests are evaluated in accordance with the criteria of the 10-point system scale indicated in the LBTU Study Regulation. The exam is organized as a written test. |
