Objectives

The course objectives are as follows:
To understand the key theories regarding the origin and evolution of viruses and parasites.
To provide students with a comprehensive understanding of the biological and molecular processes involved in the interaction between microorganisms and hosts, as well as in pathogenicity.
To explore the causes and mechanisms behind major viral and parasitic diseases.
To study the molecular mechanisms involved in antiviral resistance.
To learn about the application of key biotechnologies in the diagnosis, prevention, and treatment of infectious diseases.
These goals will be achieved through traditional lectures, seminars, and interactive activities.

Learning outcomes

At the end of the course, students should have an adequate understanding of the structure of viruses, their replication mechanisms and their evolutionary processes. In addition, students should have acquired a solid knowledge of the viruses responsible for chronic infections in humans, emerging viruses, the mechanisms of action of antivirals and the phenomenon of drug resistance.

Prerequisites

Basic knowledge of the immune response, cellular and molecular biology, and basic knowledge of genomic approaches and genetic transformation.

Lessons mode

The course consists of lectures interspersed with seminars. During the lectures, the teacher stimulates students with questions related to what has just been presented, with the aim of engaging them and encouraging them to study at home, lesson by lesson. The course also includes lectures held in the laboratory.

Frequency

Compulsory attendance, in person, as required by the course

Exam mode

The oral exam is based on questions relating to both the general part of the course (virus replication cycle, pathogenesis, etc.) and the more “specialised” part, such as HIV and drug resistance, HPV and oncogenesis. To pass the exam, students must obtain a mark of at least 18/30 in each module. Students must demonstrate that they have acquired sufficient knowledge of the topics covered during the course. To achieve a score of 30/30 with honours, students must demonstrate that they have acquired excellent knowledge of all the topics covered during the course, arguing a linear reasoning with the use of technical terms and correct linguistic expressions.

Example exam questions

Describe the replication cycle of the virus, highlighting specific aspects of certain families
Mechanisms of genetic variability in viruses and their consequences
Parasite Transmission Modes
Biological Models in Parasitology
