Iron regulates contrasting toxicity of uropathogenic Eschericia coli in macrophages and epithelial cells. Led by Deepti Dabral, van den Bogaart lab. Happy to have played a small role in it.
Metabolic interactions shape a community’s phenotype
Together with Chrats Melkonian, Michael Seidl and Justin van der Hooft, we wrote a Trends in Microbiology Spotlight on the manuscript by Yu, Correio-Melo, et al. on the role of metabolic interactions in microbial communities.
L’Oréal Unesco For Women in Science Fellowship
Last week Marjon has received the L’Oréal Unesco For Women in Science Fellowship.
The Women in Science Fellowships and rising talents awards are organized by the NIAS-KNAW, KHMW and LNVH, and sponsored by Unesco and L’Oréal.
I feel honored and grateful for this opportunity, and to be in the great company of the other awardees.

NLSEB meeting 2022
On 28 June we organize the NLSEB meeting to host all Evolutionary Biology research in the Netherlands.
Abstract deadline 2 May 2022. See link for more information & registration.
Organizing committee: Sijmen Schoustra, Koen Verhoeven, Jeroen Meijer, Marjon de Vos

Aletta Jacobs School of Public Health
Marjon joined the Aletta Jacobs School of Public Health as an Aletta Fellow.
We need all the tools in our toolbox to stop the emergence and spread of antibiotic resistance
Infections are usually treated using a straightforward paradigm: an infectious agent causes the patient’s illness, so the cure is a drug that kills the agent. This paradigm works but reality is often much more complex, explains Marjon de Vos, assistant professor of Microbiology at the University of Groningen. ‘Treatment with antimicrobials produces a selection pressure towards resistance. And this happens within a microbial community with more than one species.’

2022 Meetings in Microbial Ecology & Evolution
Two independent 4-day meetings. In both of these, we will embrace thought-provoking discussions, community engagement on cutting edge topics in microbial evolution, and informal discussions over shared meals and beautiful scenery. Applicants may apply to either or both meetings. Both meetings will feature invited speakers (please find a list in the attached poster), and we welcome applications for short talks and poster presentations. We aim to have all participants present their work.
Applications will be reviewed based on overall quality and fit for the meeting. Abstracts must be unique and specific to the theme of the meeting. As a fully trainee-organized meeting, we especially welcome applications from graduate students and postdocs. But all levels are welcome! Both meetings will be small (~60 people) and will feature meals and social activities at the venue to drive discussion and engagement. Registration and two meals per day will be provided at no cost. Participants should cover travel and accommodation, but we expect to provide need-based financial assistance for both to anyone who needs it. Please reach out to us directly for financial assistance. Applications are now open, and close on November 30th 2021 at 11:59pm. All applications will be reviewed after this deadline. We expect to send acceptance emails by mid December.
Meeting I is focused on Microbial Communities and Coevolution (May 16 – 20, 2022).
Meeting II is focused on Microbial Evolutionary Dynamics (May 30 – June 3, 2022).

Predicting Evolution Workshop
Marjon and Arjan de Visser (WUR) will give an Origins Center workshop
on Fitness Landscapes on Tuesday 9 November, 16:00h-17:00h.
Arjan and I will discuss the opportunities & pitfalls for predicting evolution and the sense & nonsense for applications such as evolutionary medicine.
You can register here for the Zoom-link.
Organizers: Liedewij Laan (TU Delft), Bregje Wertheim (RUG)
Report Zoonotic Diseases
Marjon was part of the reading group of the report on Zoonotic diseases commissioned by the Dutch government. The report was published on 6 July.
Biology is Everywhere
Marjon will give a presentation at the online symposium ‘Biology is Everywhere – Networks of Life’ of the Utrecht Biologists Association and the Department of Biology.
