Course Contents
The course aims to provide the scientific and technical skills to approach the microbiological diagnosis of infectious diseases and quality control of food. Guidelines for the collection, transport, processing, analysis and reporting of crops set up from specific sources will be provided. Information will also be provided on the main human pathogens: bacteria, fungi and parasites. In particular, basic notions of work organization will be provided in a clinical Microbiology laboratory, sterilization methods, preparation of culture media, isolation techniques, identification and for the evaluation of microbial development, microorganism conservation, observation physiological and metabolic characteristics in microbial cultures and for the determination of sensitivity to antimicrobial agents. Finally, information will be provided on food production and possible microbial contamination as a source of infectious food-related diseases.

Learning Outcomes
The course aims to provide the basic theoretical and practical technical skills related to the diagnosis of infectious diseases (of bacterial, fungal and parasitic origin) and of the microbiological control of food quality. The student acquires the basic laboratory principles and skills to isolate, characterize, conserve and manipulate bacteria, fungi and parasites, as well as theoretical notions regarding their biology and the characteristics that determine their pathogenicity. The methods of analysis of the main clinical and food matrices are also provided, as well as the competences for the interpretation of the results. Finally, during the practical part of the course the student will put into practice the concepts acquired during the course by acquiring practical skills and assessing any problems related to the reporting of results.
Prerequisites
The student must possess basic knowledge of the biology of microorganisms and, in particular, of the morphology and physiology of the bacterial cell. Furthermore, the student must know the operating principles of the instrumentation suitable for the sterilization of the growth substrates and of the glassware to be used for a correct laboratory practice. Must know the composition of the main bacterial and fungal growth substrates. It must also possess an adequate property of language and scientific mastery. The General Microbiology course is considered preparatory.
Teaching Methods
Lectures in the classroom with slide presentations and multimedia materials. Practical exercise in the laboratory using equipment such as microbiological hood, spectrophotometer, optical microscope and stereomicroscope, protocols normally used in clinical bacteriology. Discussion of the results obtained in light of the bacterial isolations obtained. Use of the websites of international organizations such as EUCAST and CLSI to obtain standard protocols and interpretative tables for the evaluation and reporting of results.
Additional Information
The control of learning, in itinere, will be carried out with exercises in the classroom and collegial discussion of results obtained in the laboratory. In particular, the different types of results obtained, and the potential variables will be evaluated in order to stimulate the acquisition of critical skills in the interpretation of the results.
Students with physical disabilities, Learning Disabilities or Special Education Needs can request specific services and tools via the Staff Sviluppo e Coordinamento Carriere e Servizi alle Studentesse e agli Studenti, consulting the University webpage: https://www.uniupo.it/en/services/services-students-physical-or-learning-disabilities
Students with disabilities, learning disabilities or special education needs, once they have contacted the University Staff, can refer to the tutor in charge of the course to define the examination modalities, concerning academic aspects.
Assessment Methods
The exam includes the presentation of a paper / report on the activity and the results obtained during the laboratory experiences, assessed in points 2 on the overall vote. The oral exam consists of a first part in which the activities carried out in the laboratory are discussed and a second part in which the students are asked some questions on the main topics covered during the course. The oral exam has the dual purpose of verifying the level of knowledge and understanding of the course contents and of evaluating the autonomy of judgment, the ability to learn and the ability to communicate. To pass the test, the student must demonstrate that he / she understands and understands at least the fundamental concepts and the most important results related to them; moreover, adequately stimulated, he must demonstrate that he is able to recognize the errors committed and therefore identify the correct ways; finally, he must be able to explain the topics in a comprehensible way. To achieve sufficiency it is necessary to know the basic techniques used in microbiology laboratories and to be able to demonstrate that they have acquired the main methods used in a bacteriology laboratory. To achieve a high grade, the student must demonstrate an autonomy of judgment and a critical sense related to the topics covered, exposing their conclusions in a clear and logical way. The evaluation is expressed in thirtieths (minimum mark 18).
