Published opinion piece: Why limit antibiotic pollution?

Me and Joakim Larsson wrote an opinion/summary piece for the APUA Newsletter, issued by the Alliance for Prudent Use of Antibiotics, that was published yesterday (1). The paper is essentially a summary of work included in my PhD thesis, and discusses how to establish minimal selective concentrations of antibiotics for microbial communities (2-4), how to identify risk environments for resistance selection (5-9), and which mitigation strategies that can be implemented (10-12). Partially, we also discussed these issues earlier in our paper in the Medicine Maker (10), but this paper goes deeper into why limiting antibiotic pollution is important to mitigate the accelerating antibiotic resistance problem. I recommend this short summary piece to anyone who would like a brief overview of our research on antibiotic resistance, and think that it can serve as a great starting point for further reading! In addition, this issue of the newsletter features very interesting pieces on reducing antibiotics use (and disposal) outside of the clinics (13) and revival of old antibiotics (14). Please go ahead to the APUA web site and read the entire newsletter!
