Learning Objectives

The aim of the course is to provide students with the main knowledge on:


1. Microorganisms and parasites: infection of the host

2. Biological essential features of microorganisms and parasites responsible for human infections

3. Mechanisms of etio-pathogenesis

5. Microorganisms and parasites responsible for human infections

6. The diagnostic principles for bacterial, viral, fungal and parasitic infections and antimicrobial susceptibility testing

7) chemotherapeutics and vaccines

Course Structure

Traditional lectures, with the support of slides and educational videos of some theoretical-practical

teaching topics.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes

with respect to previous statements, in line with the programme planned and outlined in the syllabus.
