Colistin is a last-resort antibiotic that is usually only used for severe infections with resistant bacteria. This is due to its severe kidney-damaging side effects, which occur in around 30 percent of treated patients. A research team at the Helmholtz Centre for Infection Research (HZI) and the German Center for Infection Research (DZIF) has now been able to produce an inactivated, harmless form of colistin that is only activated in the body with the help of chemical switches. In this so-called click-to-release technique, the chemical switches are specifically bound to the disease-causing bacteria. The administered masked colistin is therefore activated specifically at the site of action. The researchers hope that this could reduce side effects. The study was published in the journal Angewandte Chemie.

According to the WHO, antimicrobial resistance (AMR) is one of the ten greatest threats to global health. In the EU alone, around 35,000 people die every year from antibiotic-resistant infections. The WHO estimates that 1.27 million deaths worldwide in 2019 were directly attributable to drug-resistant infections.

Microorganisms do not just colonize the body of mammals during infections. Billions of microbes can be found on and in healthy humans and animals at any given time, communicating with each other via chemical signals and thus influencing their health. In two studies, researchers from the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS), Saarland University and Saarland University Hospital have now conducted a detailed study of the microbiome, i.e. the totality of all microorganisms, in humans and zoo animals. The aim was to identify starting points for strategies for the treatment and diagnosis of diseases. The researchers published their results in two articles in the journal Nature Communications. The HIPS is a site of the Helmholtz Centre for Infection Research (HZI) in collaboration with Saarland University.

To prepare us for future pandemics, researchers at the Helmholtz Institute for One Health (HIOH) not only look at the pathogens, but also at how changes in the environment and nature - including those caused by us - influence how pathogens have developed in the past. Prof. Sébastien Calvignac-Spencer heads the research group "Evolution of Pathogens" at HIOH and uses genetic changes to retrospectively analyse what could have caused this change. In the HZI podcast InFact, he explains how this allows valuable conclusions to be drawn about how today's pathogens could develop.

The intestinal microbiome is currently the subject of intensive research, as it is of great importance for human health. Intestinal bacteria play an essential role in the defense against dangerous pathogens, which is one of the reasons why the majority of them are among the good guys. On the other hand, some of our lodgers are more prevalent in specific diseases - for whatever reason. This also applies to the widespread but little-researched bacterium Segatella copri. The research group led by Prof Till Strowig at the Helmholtz Centre for Infection Research (HZI) wanted to determine what makes this bacterium tick. How does it adapt to its environment? And what signals does it react to?
