A job thanks to COVID—something not many people can claim. But PhD candidate Vera Arntzen can. Over the past four years, she has mapped two crucial characteristics of SARS-CoV-2 infections. Thanks to her research, experts can now make well-informed decisions on matters like quarantine duration, which…

More and more people worldwide have infections caused by bacteria that are resistant to many types of antibiotic. Why is this and how big of a problem is it?

Regardless of whether you work at a desk or in a lab, all workplaces have their risks. As your employer, the University aims to create a healthy workplace and to limit possible health risks. Here you will find the main risks and measures that we take to reduce them.

De crèche en het klaslokaal zijn misschien wel de meest gunstige plekken voor ziekteverwekkers. Toch is er relatief weinig bekend over hoe kinderen reageren op virussen en bacteriën en hoe het komt dat sommige kinderen veel beter beschermd zijn dan anderen. Simon Jochems, onderzoeker aan het Leids Universitair…

Phage therapy is a novel yet unmatured therapeutic approach in the face of the crisis of antimicrobial resistance (AMR). Dr. Tingjie Guo received a grant from the Elise Mathilde Fund and the LUF to develop innovative phage-antibiotic combination treatment strategy for combating AMR.

Rob van Wijk (LACDR, Leiden University) and Robin van den Biggelaar (LUCID, LUMC) have been awarded a €10,000 euro KIEM grant from Leiden University to start an interdisciplinary collaboration to investigate the potential of AMPK activation as an adjunctive therapy to enhance tuberculosis treatment.

Bacteria temporarily live without their cell wall if dangerous viruses are near. A remarkable feature, as the cell wall is a sturdy barrier against threats. Still, the discovery has a logical explanation ánd might be of a consequence for fighting pathogenic bacteria, according to Véronique Ongenae,…

Leiden researcher Anne-Grete Märtson brought together a large number of studies to better understand antibiotic dosing in patients with obesity. The publication in a renowned medical journal has already garnered much positive reactions, Märtson says. ‘It’s high time researchers started sharing more…

Three researchers from Leiden University have been awarded a Starting Grant by the European Research Council. The subsidy will allow the researchers to set up their own projects and put together a research team.

Cryogenic memories, antibiotic treatment for urinary tract infections and recycling plastic sustainably. These are the subjects of the three NWO-XS grants awarded to Leiden Science researchers.

The antibiotic EVG7, developed in Leiden, has proven capable of fighting the dangerous gut bacterium C. difficile with only a minimal dose. What’s more, the bacterium is far less likely to return, a major issue with existing antibiotics. The research was published in Nature Communications.

Four university medical centres, including the LUMC, are joining forces to increase pandemic preparedness in the Netherlands.

Resistance to antibiotics is a major problem in health care. Thanks to a grant from the Elise Mathilde Fund and the LUF, pharmacologist dr. Coen van Hasselt can look for new dosing schedules to reduce the development of antibiotic resistance.

'What nature made isn’t necessarily an optimized medicine to use in the human body,’ says Professor of Biological Chemistry Nathaniel Martin. That’s why a group of Leiden researchers is making a chemistry-based improved version of the frequently used antibiotic vancomycin. They received an NWO NACTAR…

Infecting each other with viruses and bacteria while protecting yourself with medicines and vaccinations. Sounds like a fun evening, right? Master students Life Science & Technology Rafael Jezior and Dennis de Beeld certainly think so. Together, they developed ImmunoWars: an exciting card game based…

Effectively treating a severe case of pneumonia is often challenging. Identifying the pathogen behind it can be difficult. PhD candidate Ilona den Hartog tried something new: ‘We searched for answers in substances our own body produces.’ PhD defence on 17 September.

eLaw - Center of Law and Digital technologies from Leiden Law School, and the Vascular Surgery Department at Leiden University Medical Centre in the Netherlands, join forces to explore the use of AI for diabetes and secondary prevention of diabetic foot problems and won a prize for it.

When a bacterium becomes more resistant to one antibiotic, it sometimes becomes more sensitive to another. To better understand this interaction, researchers from the Leiden Institute of Biology (IBL) and the Leiden Academic Center for Drug Research (LACDR) under supervision of Daniel Rozen and Coen…

Two consortia led by Leiden researchers have been awarded over one million euros by the Dutch Research Council and the Ministry of Health, Welfare and Sport to find solutions to antimicrobial resistance.

Fungi germinating in the lungs of patients. Doesn’t sound too nice, does it? Luckily, humans can deal with this normally, and we are able to clear the infection before anything comes to harm. However, in people with health issues, Aspergillosis can cause a lot of damage, especially if the fungus becomes…

It is the final stretch for the students of FGGA. Summer is approaching and they are working hard to complete everything before the summer holidays. We asked some of them how they look back at the academic year. ‘Being a mentor during HOP week is something I can recommend to everyone’

Multidrug-resistant pathogens and worldwide pandemics are increasing, making infectious diseases more prevalent. To develop new treatments, deeper knowledge of the interaction between bacteria and human cells is required. Ariane Briegel recently became a Medical Delta professor and studies such path…

Three Leiden professors have recently been awarded the most prestigious scientific accolade in the Netherlands: Maria Yazdanbakhsh and Marc Koper have been awarded a Spinoza Prize and Judi Mesman a Stevin Prize. They received their prizes on 13 October.

Dying from viral infection due to organ failure and blood loss: we still know little about how it can happen. Among other things, Huaqi Tang developed an organ-on-a-chip to figure it out. 'These technologies can offer unprecedented opportunities to fight the viruses that threaten our society.' Tang…
