AMR and climate change: a worrying dual threat to global health
Climate change and antimicrobial resistance (AMR) are forming an alarming alliance: Global warming creates new breeding grounds for resistant bacteria. A serious and very real threat to public health – but not quite the doomsday scenario some might make it out to be, says Prof Sabiha Essack from the University of KwaZulu-Natal in Durban, South Africa.

Using 3D printing technique to create biofilms
Researchers at the University of Rochester, and Delft University of Technology in the Netherlands recently developed a 3D printing technique to engineer and study biofilms—three-dimensional communities of microorganisms, such as bacteria, that adhere to surfaces. The research provides important information for creating synthetic materials and in developing drugs to fight the negative effects of…

How staphylococci protect themselves against antibiotics
The skin bacterium Staphylococcus aureus often develops antibiotic resistance. It can then cause infections that are difficult to treat. Researchers at the University of Bonn have uncovered an ingenious way in which a certain strain of Staphylococcus aureus protects itself against the important antibiotic vancomycin. The results have now been published in the journal Microbiology Spectrum.

Accumulation of drugs in the gut may reduce their effectiveness
Common medications can accumulate in gut bacteria, a new study has found, altering bacterial function and potentially reducing the medications’ effectiveness. These interactions - seen for many drugs including those used to treat depression, diabetes, and asthma - could help researchers to better understand how drug effectiveness and side-effects differ between individuals. The study is…

Random effects make it difficult to optimise antibiotic therapy
Antibiotic-resistant pathogens have become one of the greatest threats to public health. The basic mechanisms of resistance evolution have been well studied experimentally and are an important research field at Kiel University. An important factor in this context, but one that has received little attention so far, is the population size of the respective pathogen. Over the course of an infection…

Novel antibiotic deceives bacteria through mimicry
An increasing number of bacterial pathogens are resistant to antibiotics. And the most dangerous pathogens share a common feature: a double membrane that is difficult to penetrate. Even when antibiotic agents are able to break into this shell, the bacteria just pump them right out again. But a recently discovered compound called Darobactin manages to circumvent these protective measures and kill…

Antimicrobial technologies – how do they work?
Antimicrobial technologies such as coatings and textiles containing silver and copper are helping people during the Covid-19 pandemic by ensuring that whatever they touch, whether that is a door handle or their own mask, is free from live SARS-CoV-2 particles. But how exactly do these antimicrobial technologies work? How can a silver, copper or even polymeric coating kill microorganisms such as…
