Learning outcomes

At the end of the course, the student will know:

-general characteristic of bacteria, viruses, protozoa, fungi and parasites

-routes of transmission

-the establishment of pathogenic host-parasite interaction

-incubation period

-the role of immunity during infections

-the meaning of production of infection and production of disease

-the diagnosis of infection (direct and indirect). Collection of specimens, request for testing, tests employed, interpretation of tests

-basic concept of prophylaxis and therapy

-principle of treatment. Antimicrobial drugs and mechanism of resistance

-most relevant bacteria (focusing on their characteristic, mechanism of action, symptoms, diagnosis, therapy, available vaccine)

-most relevant viruses (focusing on their characteristic, mechanism of action, symptoms, diagnosis, therapy, available vaccine)

-most relevant protozoa, fungi and parasites (focusing on their characteristic, mechanism of action, symptoms, diagnosis, therapy, available vaccine).

Teaching methods

In-class lectures will be supported by video projector and PC.

Assessment methods

 

Oral examination with at least 3 questions about the course contents

The examination will evaluate whether the students have mastered the above listed skills and have reached the teaching objectives. The final oral examination will focus on specific questions about bacteriology, virology, mycology and parassitology (the mechanisms of pathogenesis, routes of transmission, microbiological diagnosis, therapy and vaccines).

Preparation on a very limited number of topics covered in the course and analytical skills that emerge only with the help of the teacher, expressed in an overall correct language --> 18-19

Preparation on a limited number of topics covered in the course and ability to autonomous analysis only on purely executive matters, expression in correct language --> 20-24

Preparation on a large number of topics covered in the course, ability to make autonomous choices of critical analysis, use of specific terminology --> 25-29

Exhaustive preparation on the topics covered in the course, ability to make independent choices of critical analysis and connection, use of specific terminology and ability to argue and self-reflection → 30-30L

Teaching tools

In-class lectures will be supported by slides. Slides will be available online at the end of the course on Virtuale platform
