Learning objectives
The objective of this course is to help the student learn molecular virology by general principles as opposed to describing each virus family. The rules for viral replication that all viruses follow are illustrated and discussed: while pointing out to the specific features of each virus, the course aims to reveal unity in the virus world rather than diversity. Host-pathogen interactions and examples of viral diseases will be discussed, with particular emphasis on the main principles of vaccine and antiviral drug development.
Expected learning outcomes
After successful completion of this course students are expected to be able to:
- Describe the diversity of virus structures and the various molecular strategies viruses use to infect and replicate in the host cell;
- Explain the molecular details of the life cycle of selected pathogenic virus and identify the implications for human disease;
- Comprehend the nature of the antiviral immune response;
- Understand the mechanism of action of antiviral vaccines and drugs;
- Describe the biotechnological importance of viruses, in particular their usage in gene therapy;
- Read, analyse and critically evaluate scientific papers in the field of virology.
Single course

Teaching methods
Lectures and discussion of scientific papers. Attendance is highly recommended. A PDF copy of the lecture slides and/or any other material used for the lectures will be made available to the students.
Teaching Resources
Flint S. Jane; Racaniello V. R.; Rall G.F.; Hatziioannou T.; Skalka A. M.
Principles of Virology - 5a Edizione (2020)
ISBN-13 : 978-1683672845

Lecture slides and note and review papers. Links to selected microbiology and/or virology WEB sites and papers will be provided.
Assessment methods and Criteria
The exam is written and consists of 3 open questions. Maximal score related to complexity of questions. Final score is the sum of scores obtained in the different sections of the exam. The time available to complete the test is 45 minutes.



The exam will evaluate:
- the ability of the student to reach course objectives in terms of knowledge and understanding
- the ability of the student to apply knowledge and understanding
- for open questions, the quality of the writing, also in terms of the ability of the student to use the correct terminology in the field of Molecular Virology and to discuss the different topics in a clear and logic way
