13 papers published on antibiotics in feed

Last week, I published 13 (!!) papers in the EFSA Journal on how to assess concentrations of antibiotics that could select for antibiotic resistance in animal feed (1-13). Or, well, you could also look at it as that the EFSA Biohaz panel that I have been a part of for more than two years published our final 13-part report.

Regardless of how you view it, this set of papers have two main takeaways:

  1. We present a method to establish Predicted Minimal Selective Concentrations (PMSCs) for antibiotics. This method uses a combination of Dan Andersson’s approach to MSCs (14) and the method I published with Joakim Larsson around five years ago to establish predicted no-effect concentrations (PNECs) for antibiotics based on MIC data (15). The combination is a powerful (but very cautious) tool to estimate minimal selective concentrations for antibiotics (1), and we have subsequently applied this method to animal feed contamination with antibiotics, but…
  2. There is way too little data to establish PMSCs for most antibiotics with any certainty. Really, the lack of data is so bad that for many of the antibiotic classes we could not make a reasonable assessment. Thus the main conclusion might be that we need a lot more data on how low concentrations of antibiotics that select for antibiotic resistance, both in laboratory systems and in more realistic settings.

Some media coverage

Here’s a nice popular summary of the paper that I published with Emil Burman last month on how temperature affects the microbial model community THOR. I think Miles Martin at The Academic Times did a great distilling my ramblings into a coherent story. Good job Miles!

I did not know about The Academic Times before this but will keep an eye on this relatively new publication aiming to popularize and distill scientific content for other scientists.

In other popularization-of-science-news, I got interviewed last week by New Scientist about a very exciting paper that came out this week on travelers picking up antibiotic resistance genes in Africa and Asia. The study was quite similar to what we did back in 2015, but used a much larger data set and uncovered that there are many, many more resistance genes that are enriched after travel than what we found using our more limited dataset. Very cool study, and you can read the New Scientist summary here.

March 2021 Pod: Antibiotic resistance evolution

In this episode Microbiology Lab Pod, the team (Johan Bengtsson-Palme, Emil Burman, Anna Abramova, Marcus Wenne, Sebastian Wettersten and Mahbuba Lubna Akter, Shumaila Malik, Emilio Rudbeck and Camille Wuyts) discusses the evolution of antibiotic resistance from different perspectives. We also interview Rémi Gschwind about his work on novel antibiotic resistance genes in the EMBARK program.

Published preprint: Road runoff microbes

I am happy to report that today a preprint on a recent collaboration with Christian Wurzbacher‘s group came out on bioRxiv. In the preprint study, we explore microbial communities in stormwater runoff from roads in terms of microbial composition and the potential for these settings to disseminate and select for antibiotic resistance, as well as metal resistance. My part of this study is quite small; I mostly provided the analysis of resistance genes on integrons, but it was a fun study and I look forward to work more with Christian and his excellent team!

September 2020 Pod: All antibiotic resistance

This is the fifth episode of the Microbiology Lab Pod and has been lying around on my computer almost finished for way too long. It was recorded on September 23, and the bigger-than-ever-before crew (Johan Bengtsson-Palme, Emil Burman, Haveela Kunche, Anna Abramova, Marcus Wenne, Sebastian Wettersten and Mahbuba Lubna Akter) is joined by Fanny Berglund to discuss computational discovery of novel resistance genes. We also discuss antibiotic resistance mechanisms, particularly in Pseudomonas aeruginosa.

The Gothenburg Society of Medicine’s research prize

I am very happy to share the news that I have been awarded with the Gothenburg Society of Medicine and the Sahlgrenska Academy’s prize to young researchers for our research on the effects of antibiotics on bacteria, including, of course, antibiotic resistance.

I am incredibly honoured by being selected for this award. I am also thrilled with that the Gothenburg Society of Medicine, which is a society mostly for medical doctors, sees the value in our broad, one-health, take on antibiotic resistance as well as other effect that antibiotics may have on microbes, both in the human body and in the environment. The recognition of antibiotic resistance as a one-health problem with solutions both within and outside of the typical medical setting is instrumental for our ability to curb future resistance development.

The award ceremony will take place in connection with the Gothenburg Society of Medicine’s closing meeting on 2 December, where I will present our research together with the senior awardee Professor Claes Ohlsson, who is awarded for his groundbreaking research on osteoporosis.

EFSA Public Consultation

For a bit more than a year, I have been part of an EFSA panel on biological hazards on cross contamination with antibiotic substances in animal feed. This week the panel has launched an open consultation on sections of the draft scientific opinion, including the proposed methodology and the data gaps identified. Anyone who are interested can submit written comments before 18 November 2020, and the full information can be found at the EFSA website.

Two fun things

Fun things on a Friday! First of all, we have updated our lab member page with some beautiful photos! Thanks Marcus for brining your camera today!

Second, our review of factors important for antibiotic resistance development in the environment has been recognised by FEMS Microbiology Reviews as one of the papers which have made the most impact across their portfolio. It has been added to a new (well, this is old news, so semi-new) collection of papers – ‘Articles with Impact’ – many of which are very well worth a read!

Have a nice weekend!

June 2020 Pod: Coronavirus galore!

In the third episode of Microbiology Lab Pod, recorded in June, a crew consisting of Johan Bengtsson-Palme, Emil Burman, Haveela Kunche and Anna Abramova goes into depth with what we knew about the novel coronavirus at the time. We also talk about Emil‘s master thesis, potential alternative antibiotic treatment regimes and the lung microbiome in cystic fibrosis.

Unfortunately, the sound quality of this episode is quite bad at times. We have tried to rescue the audio as best as we can, but it is still a bit annoying. We promise to do better next time!

More podcasting: The AMR Studio

Not only did we release the most recent episode of the lab’s podcast this weekend. Today, the episode of The AMR Studio where I’m interviewed by Eva Garmendia of the Uppsala Antibiotic Center was put online. We talk mostly about antibiotic resistance in the environment and the role that the EMBARK program can play in mitigating environmental resistance. I think it’s a nice listen (recorded in the beautiful world pre-covid-19). Find it where you find podcasts (e.g. Apple or Spotify).
