Course abstract

In this course, students of veterinary medicine acquire knowledge on the reactivity mechanisms of the animal organism which constitute protection against infectious disease agents, mainly bacteria and viruses. They get an understanding of the unwanted changes in reactivity: allergy, tolerance, autoimmune disease. The course also includes a justification for theoretical and practical issues of animal immunisation.

Learning outcomes and their assessment

Knowledge and understanding about nonspecific defence and immunity processes within an animal’s organism – 3 quizzes;
Skills to take part in a professional discussion on main topics of immunology, explain and argument professional decisions among colleges and lay persons, to interpret results from a serological testing (complement fixation test), to perform tuberculin test in animals – practical works;
Competence to assess readiness of an individual animal or group of animals for vaccination, to explain to an animal owner the role, preconditions and possible disturbances of immunization - exam.

Requirements for awarding credit points

Exam

Description of the organization and tasks of students’ independent work

Independent studies of literature as preparation for tests and exam.

Criteria for Evaluating Learning Outcomes

Three quizzes during the semester. Proportion of correct answers in each quizz should be at least 60%. Exam at the end of course. Allowed to take exam if all three quizzes done successfully. Cumulative assessment of exam (the average of grade from three quizzes) is offered for the students who have attended at least 80% of all contact hours and received 8 points (10-point grading system) in every quiz with the first try.
