B. Some environments are probably more likely than others to provide the various genetic elements typically involved in mobilization and transfer of ARGs, either through the presence of faecal bacteria known to often carry such elements or possibly because the conditions (including reoccurring stress) favour frequent gene exchanges37,38.

I. 51, 30403047 (2017). Although the natural production of antibiotic molecules most likely contributed to the (more ancient) evolution of ARGs5, it is not responsible for the rapid evolutionary expansion and spread of resistance factors across strains, species and environments that we have observed since the introduction of antibiotics as therapeutic agents.

The third step is the horizontal transfer of a mobilized resistance gene, either directly to a pathogen or via one or several intermediary bacterial hosts. 3). CARD 2020: antibiotic resistome surveillance with the comprehensive antibiotic resistance database. Int. Mutations readily occur and become fixed in the patient or animal treated with the antibiotic. A. Embolism Analysing the abundance and pattern of resistance in the environmental microbiota could therefore provide an opportunity to predict the regional resistance situation109,110,111,112,113,114 and indirectly also provide indications of historical antibiotic use115. For a resistant pathogen that is already widely circulating among humans, the consequence of a single transmission event to another individual is much more limited than for an evolutionary event leading to the emergence of a new, successful resistance genotype in pathogens, with potentially global consequences (Fig. 77. An important driver of the ancient and still ongoing evolution of resistance mechanisms is likely to be the never-ending competition for resources among microorganisms, including the natural production of secondary metabolites that are similar to many of the antibiotics used today as pharmaceuticals5,6,7. 44, 171188 (2020). Identifying such ARGs may also inform interventions to limit their spread, and enables gene-based diagnostics. Antibiotic resistance in wastewater treatment plants: tackling the black box. As bacteria and genes often cross environments and species boundaries, it is critical to understand and acknowledge the connections between the human, animal and environmental microbiota (the One Health Concept9,10) to manage this global health challenge11,12,13,14,15,16,17,18,19,20,21,22,23.
