Through the course of Microbiology students learn the basic knowledge of infectious diseases. Particular attention is given to the microbiological aspects of the oral cavity both in the state of health and disease.
At the end of the course, students will have acquired basic knowledge about infectious processes both at a general level and at the level of the oral cavity

3.Bacteria structure. Replication. Cultivation and growth of bacterial cultures. Bacterial spores
4. Structure and reproduction of fungi. Classification of the main pathogenic fungi
5. Structure of viruses and classification principles
6. Host-parasite interactions (infection, differences between infection and disease, immune response against infectious agents)
7. Sterilization and disinfection. Anti-infective drugs (antibacterial, antifungal, antiviral). Vaccines.
8. The resident oral microbial population
9. Acquisition, adhesion, distribution and metabolism of the oral resident microbial population
10. Microbiological aspects of dental plaque
11. Microbiological aspects of dental caries

3.Bacteria structure. The bacterial cell.
Wall of gram-positive and gram-negative bacteria
External wall membrane of Gram-negative bacteria: structure and toxic effects of lipopolysaccharide.
Cytoplasmic membrane: composition, transport mechanisms, osmotic regulation
Fimbriae and pili as adhesion structures and their antigenicity
Flagella and bacterial movement; concept of chemoreceptor and chemotaxis.
Organization of the bacterial chromosome
Bacterial spore: structure, resistance to physical and chemical agents, regulation of sporulation and germination, biological and medical significance.
4. Structure and reproduction of fungi. Classification of the main pathogenic fungi. Differences between fungi and bacteria

Assembly, maturation and release of viral particles
Cytopathic effect: morphological aspects and molecular mechanisms.
Mutations, genetic recombination and gene reassortment as the cause of viral variability.
7. Sterilization and disinfection: Biological bases of the action of physical and chemical agents. Anti-infective drugs (antibacterial, antifungal, antiviral). Biological bases of selectivity and main mechanisms of action.
Criteria for the choice of drugs and for the use of associations
Vaccines.
8. The oral resident microbial population: bacterial species present, interaction between microbial communities of the oral cavity in the state of health and disease
