PhD on antimicrobial resistance in case of gut dysbiosis

The gut resistome, i.e. all antibiotic resistance genes (ARGs) circulating in the gut, determine the microbiome dynamic, i.e. how an individual’s gut microbiome will respond to and recover from an antibiotic therapy. Moreover, the gut resistome is also a source of ARGs conferring antimicrobial resistance to virulent or clinically relevant strains. The horizontal gene transfer (HGT) between bacteria can occur in any environment and particularly when bacterial loads are high, like in the gut. Notably, the gut microbiomes of diseased individuals are enriched in facultative pathogens which encode ARGs and might have an increased infective competence. A risk assessment of ARG excretion caused by gut dysbiosis will be established by combining data obtained about the frequency of ARG transfer events by transduction in case of gut dysbiosis and the survival of AMR bacteria in surface water as well as their competencies to transfer ARGs into the environment.
