New technique could prevent dangerous biofilms on catheters

Biofilms frequently coat the surfaces of catheters, and of various medical implants and prostheses, where they can cause life-threatening infections. New research at the Sahlgrenska Academy show that coating implants with ...

Chemists turn bacterial molecules into potential drug molecules

Yan-Yeung Luk, associate professor of chemistry, and his research team have published their findings in ChemBioChem, explaining how they have created molecules that mimic and dominate toxic ones secreted by bacteria. The ...

Mechanical forces control the architecture of bacterial biofilms

As hide-outs for bacteria, biofilms cause problems for antibiotic treatment or the cleaning of medical tubes. They contribute to the spreading of antibiotic-resistant bacterial strains. A biofilm is created when bacteria ...

Strategies to decrease bacterial colonization

Among the bacterial infections that are most difficult to treat, chronic infections associated with bacterial biofilms are one of the most hazardous. Bacterial biofilms are densely packed communities of microbial cells surrounded ...

Team identifies the off switch for biofilm formation

Bacteria are best known as free-living single cells, but in reality their lives are much more complex. To survive in harsh environments, many species of bacteria will band together and form a biofilm—a collection of cells ...
