Course objectives
This course aims to provide an understanding of how viruses are built, how they infect and replicate in host cells, how they spread, evolve and cause disease. This is structural and molecular virology course with the aim to provide understanding of basic mechanisms controlling the virus life cycle. While it is focused primarily on human and animal viruses, it will also discuss bacteriophages. The course will explain important applications of virology, including: virus-based gene therapy; developments of virus-based vaccines; use of “oncolytic” viruses to treat cancers; ability bacteriophages to combat human and animal bacterial diseases. We will also discuss emerging viruses and potential bioterrorism agents.
Learning outcomes
By the end of this course, students should be able to do the following:
Understand what is a virus. Have your own opinion as to whether viruses are alive or not. Understand basic concepts in virology related to strategies of virus cell entry, replication, particle assembly, release of virions from cells, and virus structure. Describe how the simplicity of viruses enabled groundbreaking discoveries of fundamental concepts in biology such as: o Demonstration that genes are composed of DNA o Discovery of Internal Ribosomal Entry Site (IRES) o Discovery of transcription enhancers o Discovery of translation factors Critically analyze what you read in scientific journals. Have a general overview of virus taxonomy. Be familiar with viruses that cause severe diseases in humans or are economically important pathogens of agricultural animals and plants. The gained knowledge and skills will be useful for basic and applied virology research. The critical analysis of published research may be useful for any field of research enterprise.

Teaching methods
The course will be presented as a series of lectures presented with the aid of PowerPoint slides.
Assessment methods
Final grade will be calculated according to Table 1 based on following performance indicators:
Two Mini-Research Assignments (each of them is worth 10% of your final grade). The assignments will take a form of short papers. Detailed instructions explaining the assignments will be posted on www in the “Mini-Research Assignments” section. All Mini-Research Assignments will be due at 10:30am on the day listed in the Course outline section of this syllabus. Taking off 1% for each day the assignment is late will penalize late work. Mini-Research Assignments should be submitted in electronic form only. Final exam (90% of your grade). The final exam will be a mixture of multiple choice and essay questions. Table 1. Grading scale. A 100-91%; B 90-81%; C 80-71%; D 70-61%; E 60-51%; F 50-0%

Teacher's information
Course Format In this course, you will be acquiring knowledge in two main ways: in the lectures and by home study (which means by reading the assigned materials and working on assignments and homeworks). Reading the material will give you a base of factual knowledge. It will also introduce you to the main theoretical points. The lectures then will reinforce your understanding of the material. The lectures will also introduce you to concepts and theories that are not covered by the readings. Class sessions will also be a space for discussions.

Class rules Before coming to class, please turn off anything that beeps or rings. Please, help create a nice learning environment for yourself and your classmates. Reading any material that is not related to the class, texting, or checking the internet during the class is rude and will not be tolerated. Please refrain from eating during class. Having something to drink is fine. If you have any question regarding the material being discussed in class, do not hesitate to ask. If you ask such question, it will help to clarify the issue not only for you but for your peers as well! In class discussions, be respectful of other students' opinions. You have the right to hold and express whatever opinion on the discussed topic, no matter how unacceptable they may seem to your classmates. They can disagree with you by they must respect your right to hold your opinion. Likewise, you must respect their right to express their views freely.

Academic Integrity You are required to adhere to the following the rules of academic integrity (as described in „Disciplinární řád pro studenty”). You are prohibited from (among other things): cheating, lying, stealing, and deceit in any of their diverse forms (such as use of ghost-written papers, the use of substitutes for taking examinations, the use of illegal cribs, plagiarism, and copying during examinations). Violations of academic integrity will result in sanctions. These sanctions range from taking off points from the particular part of the grade to assigning „Failed“ as the final grade in the class. The decision about the sanction for academic dishonesty is entirely at the discretion of the instructor. All cases of academic dishonesty will be reported to the „Disciplinární komise PřF MU“ (disciplinary commitee).
