LEARNING OUTCOMES
Aim of the course:
The course’s theoretical syllabus aims to the comprehension of the ‘microcosm’ and its reaction with the ‘macrocosm’ and human. An introduction to the evolution of Microbiology field is occurring as well as a historical throwback to the most important discoveries. The microorganisms’ variety and structure and the function of the bacterial/viral cells is described, along with the evolution of bacteroides, bacteriophages, plasmids and viruses’ basic genetic systems. It is completed with an introduction to antibiotics and the genetic structure of the bacterial antibiotic resistance mechanisms as they grow and the means to measure and control the antimicrobial resistance
Objectives and expected learning outcomes:
Upon completion of the course, students will be able to know and understand:
- The Epidemiology meaning and the most known diseases caused by bacteria, viruses, fungi and parasites.
- The microorganisms’ role in food production and conservation and their ability to cause infections transmitted by food (foodborne diseases).
- The development of theoretical and practical skills in planing and executing experiments.
- How to use general texts, reference books and series of other sources in order to acquire further knowledge during the abiding independent knowledge.
- The way of developing a research study either individually or in teams (searching for related bibliography, evaluating data and writing).
