News • Model organisms evolved too far

How lab bacteria became 'estranged' from their real-life counterparts

A model organism used in laboratories for the past 100 years has evolved so extensively that it may no longer be fit for purpose, according to a new study on bacterial strain Escherichia coli K-12.

Colorectal cancer surgery: gut microbiota helps healing

In a promising study, Canadian researchers have shown for the first time in mice that modifying intestinal flora before surgery could reduce postoperative complications in colorectal cancer patients.

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…

News • Resistance mechanism discovered

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.

News • Altered bacterial function

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…
