We analyze which bacteria, when, and by what mechanism exchange genetic material in their native environments. Increasing levels of antibiotic resistance in human bacterial pathogens represent one of the most pressing medical challenges of our time. HGT plays a critical role in spreading of antibiotic resistance genes in bacteria. Currently no solution exists to reverse the antibiotic resistance or prevent it from further spreading via HGT apart from the conservative approach of antibiotics stewardship, that has so far showed limited success in eliminating the resistant strains. Therefore, we study mechanism and regulation of HGT in human pathogenic and commensal bacteria with a far-reaching goal of countering antibiotic resistance spread by modulating DNA exchange.
