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!

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.

1. 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.
