GENERAL MICROBIOLOGY Aims of Microbiology, characteristics of the microbiological world, concepts of infection and disease. The prokaryotic cell. Structure of gram-positive and gram-negative bacterial cells. Metabolism, reproduction and production of spores, cultivation, genetics and pathogenic action of bacteria. Viruses: structure, multiplication, cultivation, pathogenic action. Yeasts: structure, multiplication, cultivation, pathogenic action. The immune response: natural defences, concept of antigen, humoral and cell-mediated immune response, antigen-antibody reactions, inflammatory mediators. Bacteriological examination: sampling, direct examination, colours, culture examination, response times, serological tests. Antibacterial drugs and antibiogram. Disinfection and sterilization. Special microbiology Gram positive. Staphylococci. Streptococci. Listeria. Bacilli. Mycobacteria. Gram negative: Enterobacteria. Non-fermenting bacteria. Vibrios. Neisserie. Yersiniae. Brucella. Legionella. Classification of viruses, families, main viruses of medical-environmental interest. Fungi and Parasites of medical and environmental interest. ENVIRONMENTAL MICROBIOLOGY Definitions. Microbial communities and interactions: concepts of population, community, habitat, niche, consortium. Advantages of living in community: homeostasis, colonization, selection by the environment, suitability of microorganisms. dispersion and persistence. Diversity of prokaryotes, food chains. Nutrition and ecology. Colonization and succession. Interaction between microorganisms: commensalism, protocooperation, mutualism, symbiosis, competition, amensalism, parasitism, predation. Microorganisms and their ability to cause environmental changes: biogeochemical cycles. Microorganisms and environmental pollution. Atmospheric microbiology. Water microbiology. Food microbiology.
