The presence of micropollutants in water, such as pesticides, antibiotics and biocides, is a consequence of their use in industry (agriculture, livestock, etc.), clinics and households. The presence of these compounds can favor the selection of some microorganisms over others, altering the microbial composition of the affected system, such as rivers, lakes and the land through which they flow. Some of these microorganisms contain antibiotic resistance genes and can also be transferred to other microorganisms with which they share a niche. All this would facilitate the dissemination of these genes, ultimately reaching man. Points of interest:
- As the presence of micropollutants can affect the distribution of different bacterial populations.
- The presence of bacteria with antibiotic resistance genes in these media.
- Selection of mutations in the presence of microcontaminants, allowing the resistance of the microorganism.
- Study of the biological cost of acquiring mutations or genes that provide resistance to microcontraminants.
- The transfer of resistance genes between microorganisms and the effect of the presence of micropollutants on this process.
