PRINCIPI DI MICROBIOLOGIA E BIOTECNOLOGIE MICROBICHE APPLICATE A - LModule PRINCIPI DI MICROBIOLOGIA
Academic Year 2023/2024 - Teacher: Pio Maria FURNERIExpected Learning Outcomes
- Identify the different types of relationships that microorganisms and human parasites establish with the host, differentiating the "infection" phenomenon from the "disease" one.
- Correlate the aggressive mechanisms of microorganisms and parasites with the various "types" of infection and the pathological lesions induced.
- Classify microorganisms and parasites within the various stages of aggregation of living matter (metazoans, prokaryotes, eukaryotes, viruses), correlating the degree of organization with the pathogenic action.
- In the context of the structural organization of microorganisms and parasites, identify the structures/functions necessary to carry out metabolic processes and replication and to determine infection/disease in the host.
- Correlate the phenomenon of variation and mutation of microorganisms and parasites with the pathogenic action and resistance to antimicrobial substances.
- Describe and classify the inhibitory mechanisms, the site of action, the spectrum of action of chemoantibiotics, antivirals, antifungals and antiprotozoans.
- Indicate the biological prerequisites of chemo-antibiotic resistance (genotypic and phenotypic) and resistance to other antimicrobial agents (antiviral, antifungal, antiprotozoal).
Course Structure
