Learning objectives

The integrated course aims to allow students to know and understand basic concepts and updated scientific knowledge concerning the taxonomic, morphological, physiological, genetic, pathogenetic, epidemiological, immunological and pharmacological characteristics of microorganisms and viruses, as etiologic agents of infectious diseases in humans. It also aims to provide the ability to evaluate, interpret and manage microbiological and virological approaches for the diagnosis, therapy and prophylaxis of oral infections and control of care-related infections in dentistry. Furthermore, it also aims to provide students with knowledge of epidemiological methods for assessing health phenomena and health needs. The Students will be able to apply epidemiological skills in reading and interpreting scientific articles. They will acquire an autonomy of judgment and learning related to the topics covered and specific communication skills.

Prerequisites

None

Course unit content

The integrated course includes the treatment of aspects related to: general characteristics, genetics, metabolism and cultivation of microorganisms and viruses, host-parasite relationships in infection and infectious disease (pathogenicity and virulence), general characteristics of the main infectious diseases, antimicrobial and antiviral drugs and related mechanisms of resistance, infection and immunity and prevention of infectious diseases. Particularly in-depth will be the topics related to Oral Microbiology, including oral microbiota, plaque, caries, periodontal diseases and their control. The criteria of the direct and indirect microbiological diagnosis, the microbiological and virological microscopic, cultural and serological tests and the in vitro susceptibility testing of microorganisms to the anti-infective agents will also be treated. Finally, the objectives of epidemiology and epidemiological methods will be discussed as fundamental tools for identifying public health problems, identifying risk and protective factors, planning and evaluating public health interventions.

Teaching methods

The topics concerning the contents of the course will be presented and discussed through lectures. The main concepts of each topic will be exposed, emphasizing the links between the various parts of the course and encouraging the active participation of the students. Lectures will be held on-site in compliance with safety standards, provided that further instructions on the ongoing health emergency are not implemented. Supporting material will be available on the specific, student-reserved platform (Elly) and will include slide presentations of the lectures.

Assessment methods and criteria

The assessment of the achievement of the objectives set by the course will be carried out by means of an oral exam in presence or telepresence, with the support of the Teams platform (guide http://selma.unipr.it/). No interim evaluation is programmed. Questions on the topics relating to the course content will be used to ascertain the student’s knowledge and understanding of the scientific discipline and whether is able to use appropriately the technical-scientific language and to apply the knowledge acquired in the exercise of the profession. Failure to answer to one question, or proven inability to demonstrate at least a basic knowledge on the subject, will prevent the successful completion of the exam. Upon successful completion of the exam, the attribution of the grade, expressed in thirtieths, will be based on the degree of achievement of the objectives (excellent, good, fair, fully sufficient, sufficient, in the range between 30/30 and 18/30) and on the basis of the weighted average of the scores obtained in the different modules (Microbiology and Clinical Microbiology - 6 CFU, Principles of microbiological diagnosis - 2 CFU, General and applied hygiene - 2 CFU). Honors will be awarded to students who have demonstrated particular communication and autonomous learning skills. The result of the exam is communicated immediately to the student, and, after its acceptance, is then published on the ESSE3 portal (https://unipr.esse3.cineca.it/Home.do). Students with SLD/BSE must first contact LE Eli-che: support for students with disabilities, D.S.A., B.E.S. (https://sea.unipr.it/it/servizi/le-eli-che-supporto-studenti-con-disabilita-dsa-bes).
