Learning outcomes of the course unit

The objectives of the Microbiology course are to enable the acquisition of knowledge and understanding about basic microbiology (morphology, structural organization, genetics and classification of bacteria, fungi, protozoa and viruses; host-pathogen interactions and pathogenesis of infectious diseases; mechanisms of action and use of common antimicrobial and antiviral agents and their mechanisms of resistance; host immune response to infectious agents and prevention of infectious diseases; recombinant DNA and pharmaceuticals).
The objectives of the General Pathology course are to enable the acquisition of knowledge and understanding about etio-pathogenetic mechanisms of human diseases with their related essential notions of semeiotic and medical terminology and mechanisms and alterations of the innate and adaptive immune response. Great emphasis will be given to molecular pathology, oncology and immunology in order to allow the student to apply the knowledge gained to understanding the mechanisms of action of drugs and to identify new potential therapeutic targets.

The integrated course also aims to provide the ability to apply in occupational contexts knowledge and understanding acquired in the fields of Microbiology and General Pathology.

Prerequisites

Getting through General Physiology and Biochemistry/Applied Biochemistry.

Teaching methods

The arguments regarding the courses content will be presented and discussed through lectures, with the aid of iconographic material.Lectures will present the main conceptual frame of each subject, summoning questions or doubts from the students.

Assessment methods and criteria

Learning outcomes will be verified through an oral examination. It 's possible for the student to address separately the parts of Microbiology and Pathology, as partial exams. Questions on the topics relating to the courses content will be used by different examiners to test the student’s knowledge and understanding in the two scientific disciplines, and her/his ability to apply them in occupational contexts. Failure to answer to questions on one of the courses , or proven inability to demonstrate at least a basic knowledge of the subjects, will prevent the successful completion of the exam. Upon successful completion of the examination, the attribution of voting will be carried out according to the degree of achievement of the objectives (excellent, good, fair, fully sufficient, barely sufficient). The final vote will be decided jointly by the examiners, who will have the possibility to decide a vote not higher or lower than three grades from the best or the worst vote derived from the mean of the two individual votes. Full marks with laude will be reserved to students exhibiting, together with an overal evaluation of 30/30, capability of making judgments and good communication ability and autonomous learning skills.
