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.

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).
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.
We are hiring a postdoc to work with environmental monitoring of antimicrobial resistance. The project is part of the EMBARK program and will consider different aspects of establishing a baseline for background antibiotic resistance in the environment, standardization of monitoring protocols and development of methods to detect emerging resistance threats. The project will involve work with environmental sampling, DNA extractions, bacterial culturing and generation of large-scale DNA sequence data. In terms of bioinformatic analyses, the project will encompass analysis of next-generation sequence data, genome-resolved metagenomics, short-read assembly and network analysis.
We look for a skilled bioinformatician, preferably with experience of experimental laboratory work. If you feel that you are the right person for this position, you can apply here. More information is also available here. We look forward to your application! The deadline for applications is January 3.
I am very happy to announce today (on the European Antibiotic Awareness Day), that the EMBARK project that I am coordinator for got funded by JPIAMR with almost 1.4 million Euros over three years!
The primary goal of EMBARK is to establish a baseline for how common resistance is in the environment and what resistance types that can be expected where. That background data will then underpin efforts to standardize different methods for resistance surveillance and identify high-priority targets that should be used for efficient monitoring. In addition, EMBARK will develop and evaluate methods to detect new resistance factors and thereby provide an early-warning system for emerging resistance threats.
EMBARK is an international collaboration funded by JPIAMR. The consortium consists of myself, Thomas Berendonk (TU-Dresden, Germany), Luis Pedro Coelho (Fudan University, China), Sofia Forslund (ECRC Max-Delbrück-Centrum für Molekulare Medizin, Germany), Etienne Ruppé (INSERM, France) and Rabaab Zahra (Quaid-i-Azam University, Pakistan).
EMBARK has a website where the protocols and data generated during the project will be released. Follow our progress towards better monitoring of antimicrobial resistance in the environment here and on the EMBARK Twitter account: @EMBARK_JPIAMR!
