General characteristics, organization and maintenance of bacterial genomes Coding density, genome size vs. bacterial lifestyle, operonization, replication-dictated biases, superhelicity, DNA damage response Sources of genetic variability Mobile genetic elements and their biology (transposable elements, phages, plasmids, ICE), anti-MGE defense mechanisms, horizontal gene transfer (transformation, transduction, conjugation), spontaneous mutations (classification, origins), repair mechanisms, hypermutation. Essentials of genetic manipulation of bacteria Inactivation of genes, introduction of genes into heterologous hosts, measuring and modulating gene expression, model eukaryotic host cells/organisms Genetic basis of host association and pathogenicity Nosocomial vs. resident bacteria, intestinal vs. mucosal resident bacteria, molecular mechanisms of immune evasion, pathogenicity islands and MGEs, adaptation to obligate intracellularity, host spectrum and host switches/shifts Population genetics of pathogenic bacteria Definition of bacterial species, MLST schemes, whole-genome sequencing (major platforms and types of sequencing data, assembling genomes, genotyping), core- and accessory genome, genetically monomorphic pathogens. Genetics of ATB resistance ATB production and resistance in natural ecosystems, intrinsic resistance in nosocomial vs. resident bacteria, low-level (efflux, envelope permeability) vs. high-level (ATB modification, target mutation) resistance mechanisms, modes of resistance development (mutational vs. horizontal acquisition), development of transmissible resistance Poslední úprava: Nunvář Jaroslav, RNDr., Ph.D. (13.12.2024)
