Environmental dissemination of Antimicrobial Resistance in water and soil ecosystems

Activity: Talk or presentationTalk or presentation at a workshop, seminar, course or other meeting


Antimicrobial resistance (AMR) is a growing and significant challenge to global public health. Currently, AMR is approached from a “One Health” perspective, which includes exploring the occurrence of AMR in animals, humans, the environment, and its transmission between them. Agricultural practices and wastewater treatment plants are among the primary sources of antimicrobial resistance in the environment. Large amounts of manure are produced from livestock at the farm level, and one of the most common ways to use it is by applying it as soil fertilizer. However, manure application to soils also results in the transport of antibiotic-resistant bacteria (ARB), antibiotic resistance genes (ARGs), and partially metabolized antibiotics, which results in environmental contamination of manured soils and surface water.

In this talk, I discussed how manure application affects the native soil microbial community and the fate of antimicrobial resistance genes (ARGs) in the environment, including the main factors contributing to ARG decay dynamics and horizontal gene transfer. I will presented a potential new approach to wastewater treatment, i.e., phage therapy.
