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.
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.
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!
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!

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).
In the second episode of Microbiology Lab Pod, a crew consisting of Johan Bengtsson-Palme, Emil Burman, Haveela Kunche and Anna Abramova discusses how to identify novel resistance genes with our special guest Marlies Böhm. We also talk about bacterial virulence: how do bacteria become virulent, how do virulence relate to competition, how do bacteria evade the immune system and can we attenuate virulence using fatty acids?

In the very first episode of the Bengtsson-Palme lab podcast, a crew consisting of Johan Bengtsson-Palme, Emil Burman, Haveela Kunche and Anna Abramova discusses the origin of the novel coronavirus, interactions between influenza and the respiratory tract microbiome, resistant bacteria in glaciers, pathway analysis methods, a new genus of bacteria discovered in Gothenburg, as well as life in research during a global pandemic.

I guess it hasn’t passed anyone by that we are under a global lockdown (although to very different degrees – Sweden, where we’re based, has a pretty relaxed attitude to quarantining people (1), so it could be worse for us, I guess). In any case, the novel coronavirus has forced the lab to largely work from home and has upended essentially all my plans for this spring, expect for writing grant applications (which I have done a lot).
First of all, I want to thank my fellow lab members for holding out strongly in these trying times. They have consistently shown that they are the best co-workers I could ask for, and have kept calm even when anxiety hits. Thanks a lot for that. I also would like to thank the university for providing rather clear guidance on how to handle different issues that come up in these time of crisis.
With that said, I am also sad to say that there will not be a Microbiome & Probiotics Collaboration Forum in Rotterdam on May 18-20. Instead that meeting has been postponed to early December. Similarly, I will not be in Helsinki next week to talk about EMBARK. That workshop will instead, hopefully, take place on August 28. And the same story goes for the NordicMappingAMR organised by the Swedish Medical Products Agency, which will take place at a later date (I am not sure exactly when this is planned yet).
These are trying times for all of us. I hope that you stay healthy and take care of your loved ones – particularly the elderly, but not unnecessarily visiting them. My grandparents (aged 93 and 95) have started FaceTiming us, so I guess some good things come out of this mess as well. We will come out of this crisis stronger, eventually.
- There are many things I could say about the Swedish strategy regarding covid-19, but this is not really the forum. In very brief, though, I have quite some faith in that the Swedish Public Health Agency is doing a decent job. Mistakes have been made (particularly early in the pandemic) and I am slightly anxious whether the Swedish strategy will play out as well as in other countries in Northern Europe, but right now data suggest that we are doing reasonable fine. I might return to this issue in another post if time permits.
I am a bit late on the ball here, but January was a great month for the lab in terms of funding. First, we got awarded an Sahlgrenska Academy International Starting Grant – a faculty grant for young researchers comprising of 1 million SEK, intended to support the overall research plan for the lab.
The second grant was awarded by the Centre for Antibiotic Resistance Research (CARe) at the University of Gothenburg and is a project grant focusing on opportunistic pathogens and their role in the emergence and transmission of antibiotic resistance. For this project, we got almost 600,000 SEK over two years to investigate how genes enhancing invasion ability and virulence interact with selection for antibiotic resistance in opportunistic pathogens. The project is somewhat related to the work I did in Prof. Jo Handelsman‘s lab, but extends it to more mechanistic details about how these phenomena are interconnected.
Here’s some updates on my Spring schedule.
On March 19, I will be presenting the EMBARK program and what we aim to achieve at a conference organised by the Swedish Medical Products Agency called NordicMappingAMR. The event will feature an overview of existing monitoring of antibiotics and antibiotic resistant bacteria in the environment. The conference aims to present the results from this survey, to listen to experts in the field and to discuss possible progress. It takes place in Uppsala. For any further questions, contact Kia Salin at NordicMappingAMR@lakemedelsverket.se
Then on May 18 to 20 I will participate in the 7th Microbiome & Probiotics R&D and Business Collaboration Forum in Rotterdam. This industry/academia cross-over event focuses on cutting-edge microbiome and probiotics research, and challenges and opportunities in moving research towards commercialisation. I will talk on the work we do on deciphering genetic mechanisms behind microbial interactions in microbiomes on May 20.
And finally, I also want to bring the attention to that my collaborator Erik Kristiansson has an open PhD position in his lab. The position is funded by the Environmental Dimensions of Antibiotic Resistance (EDAR) research project, aiming to describe the environmental role in the development and promotion of antibiotic resistance. The focus of the PhD position will be on analysis of large-scale data, with special emphasis on the identification of new forms of resistance genes. The project also includes phylogenetic analysis and development of methods for assessment of gene evolution. More info can be found here.
