Assessment methods

The final examination test is designed to verify the achievement of the following learning objectives:

- Knowledge the biological features of microorganisms and viruses;

- Understanding of the cellular and molecular basis of microbial and viral pathogenicity and host-microorganism interactions;

- Knowledge the methods of microbiological and virological analysis and targets of action of antimicrobial and antiviral drugs;

- Knowledge the main bacteria, fungi, protozoa and viruses etiologic agents of infectious diseases, their clinical-diagnostic aspects and elements useful for understanding appropriate therapy

The assessment of learning only occurs through thefinal examination which consists of an oral interview.
