Objectives

MICROBIOLOGY AND CLINICAL MICROBIOLOGY
At the end of this course students should:
- be able to describe the structure and function of microorganisms;
- be able to describe the mechanisms of infectious disease transmission and pathogenicity;
- be able to describe in detail those classes of microorganisms of specific relevance to the common diseases.

HYGIENE AND PUBLIC HEALTH
The teaching contributes to the realization of the educational objective of Dietistic Course of training professionals able to apply preventive medicine strategies to the main human pathologies. Expected learning outcomes
Knowledge and understanding
At the end of the teaching lessons the student will:
- know the basic concepts of epidemiology and prophylaxis of infectious diseaes
- know the methods of food preservation and the epidemiology and prophylaxis of the main food poisonings
Ability to apply knowledge and understanding
At the end of the teaching lessons the student will:
- Knowing how to plan and carry out nutritional surveillance activities with targeted collection of epidemiological data on food consumption, applying hygiene rules for the prevention of food poisoning; plan and participate in the implementation of food education programs.
Autonomy of judgment
At the end of the teaching lessons the student will:
- know how to evaluate and interpret experimental data.

Contents

MICROBIOLOGY AND CLINICAL MICROBIOLOGY
The course provides learning in the basic principles of medical microbiology and infectious disease. It covers mechanisms of infectious disease transmission, principles of aseptic practice, and the role of the human body’s normal microbiota. The biology of bacterial, viral, and fungal pathogens and the diseases they cause are covered. The course provides the conceptual basis for understanding pathogenic microorganisms and the mechanisms by which they cause disease in the human body. Classes of microorganisms of specific relevance to the common diseases will be discussed in detail.

HYGIENE AND PUBLIC HEALTH
The course aims to provide non only the the basic knowledge of epidemiology and prevention but also to treat aspects of food hygiene more closely related to dietetics.

Extended Syllabus

MICROBIOLOGY AND CLINICAL MICROBIOLOGY
Difference between Prokaryotic and Eukaryotic cells.

Teaching Methods

Teaching method: frontal lectures and material provided by the teacher.

Evaluation methods

Verification of learning:

The exam method is an oral test designed to verify the results of the expected learning, in accordance with the educational and specific objectives of the course. The oral examination is placed at the end of the course, after having achieved the attendance to the same, according to a schedule established and published on the University web page at the beginning of the academic year. The outcome of the test is evaluated as the result of learning the specific and training objectives, such as knowledge and understanding, capacity for logical integration and application. At the end of the test each teacher will form an opinion expressed in terms of Italian grades and their correspondent European Credit Transfer System grade (In Italian Universities grades are given on the basis of 30 points).
1) Rating 30 - 30 cum laude (corresponding to ECTS grade A): Excellent knowledge and understanding of the subjects, ability to reason and logical integration of the acquired knowledge. If the student, who has achieved this evaluation, demonstrates autonomy of judgment, high communication skills and autonomous learning skills, a laude can be added by the commision. 2) Rating 27 - 29 (corresponding to ECTS grade B): Good knowledge and understanding of the topics with some non-serious inaccuracies and with a good capacity for logical integration and judgment.
3) Rating: 23 - 26 (corresponding to ECTS grade C): Discrete knowledge and understanding of the topics and, despite some gaps in the ability to integrate and apply knowledge.
4) Rating 20 - 22 (corresponding to ECTS grade D): Knowledge and understanding of the arguments fully sufficient, although there are clear gaps, which are reflected in a reduced capacity for integration, logic and application.
5) Rating 18 - 19 (corresponding to ECTS grade E): Knowledge and understanding of the topics with serious and evident gaps, with limited integrative and applicative skills, but which also allow the passing of the exam.

N.B. For Integrated Courses (exams covering more than one module or course unit) a single exam will be held and a final grade given.
