MICROBIOLOGY AND HYGIENE
Learning outcomes of the course unit
Acquisition of the scientific expertise instrumental to the understanding of the taxonomic, epidemiological, morphological, physiological, immunological and pharmacological characteristics of bacteria, fungi, parasites and viruses responsible for infectious diseases in man and capacity of evaluation, interpretation and managing of microbiological and virological approaches for the diagnosis, therapy, prophylaxis and control of the infections of the oral cavity and cross-infections in dentistry.
Acquisition of the basic tools and methodology to enable the understanding of the concepts and contexts for the application of the prevention of infectious and chronic degenerative diseases as well as the fundamentals of the epidemiology applied (concept of risk factor, causality relationship, epidemiological studies).
