“…Even in areas not closely associated with human activity, antimicrobics and associated resistance genes can be found. Water serves as an important vehicle for ARMB and free ARGs, traveling to other regions through rivers as reported in Costa Rica where detection of antibiotics and other drugs were found in rivers (Vargas-Villalobos et al 2024). Furthermore, the use of antimicrobials in aquaculture has an impact on the spread of AMR, but its role is not entirely clarified.…”

Tackling the global threat of antimicrobial resistance (AMR) requires joint efforts according to the principles of the One Health approach. In this context, wildlife, and especially wild birds, are recognized as an important bridge between environment, humans and livestock in perpetuating AMR. Over the last decades, important progress has been made in understanding the role of wild birds as carriers of antibiotic‐resistant bacteria and their genes (ARGs) within ecosystems; however, there are still many knowledge gaps regarding transmission sources and routes. This commentary summarizes studies from recent years focusing on AMR in wild birds, highlighting the most frequently found zoonotic bacteria harboring ARGs and the possible exchange scenarios between humans, livestock, and wild birds. We emphasize the need to standardize and optimize a wild bird monitoring approach for AMR surveillance that includes non‐invasive sampling methods, culture‐independent techniques for identification of ARGs, database integration and implementation, and machine learning technology. This multidisciplinary perspective, which could involve veterinarians, biologists, ornithologists, conservationists, and managers, may represent part of the solution, not only for wildlife conservation but also for global health, considering that the goal is to reverse the route of AMR.

“…This situation is worsening due to the lack of legislation, as with few specific exceptions, they are not being monitored. Because of their high biological activity, pharmaceuticals are among the groups of micropollutants that are receiving increased attention within the scientific community. − Thus, indirect control measures to estimate their elimination during ozone treatment would be very interesting to mitigate the release of these bioactive and toxic contaminants that affect the quality of the aquatic resources and drinking water . Thus, the objective of this study is to develop an index that establishes a correlation between the inactivation of total coliforms and E.…”

Despite the well-known efficiency of ozonation in treating secondary effluents and its increasing global application, the removal of micropollutants is still a matter of concern. Ozone installations for tertiary treatment are typically installed with specific objectives such as disinfection, color and odor removal, and micropollutant removal, among others. However, due to factors such as the absence of legislation in many countries, complexity, and cost of analysis, for example, the accurate assessment of micropollutant removal during ozonation is limited to a few legislated compounds. This study aimed to contribute to the evaluation of pharmaceutical removal by introducing an index that correlates the inactivation of common bacteria widely used as disinfection indicators (total coliforms and Escherichia coli) with the removal of micropollutants during ozonation of secondary effluents. The developed index, named Microlog, was tested in three different wastewater treatment plants and compared with existing literature data. Strong correlations were observed between the log 10 reduction of bacteria and the percentage of specific micropollutant removal, regardless of the effluent quality. The Microlog concept can serve as an additional tool for assessing the final removal of micropollutants when the ozone disinfection of the wastewater treatment plant effluent is measured.
