Bacteria can develop resistance to antibiotics with the result that these drugs no longer work. Particularly problematic are pathogens which develop multi-drug resistance and are unaffected by most antibiotics. Scientists world-wide therefore search for new classes of antibiotics. Scientists from Göttingen have now presented a new promising approach to using antivitamins as a therapeutic alternative to conventional antibiotics.
A team of scientists at the MPI for Biophysical Chemistry as well as the Universities of Dundee (UK) and Groningen (Netherlands) has now clarified how potassium ions slip through potassium channels so efficiently and exclusively: They pass through the channels “naked”.
An international team of scientists has discovered how an important natural antibiotic called dermcidin, produced by our skin when we sweat, is a highly efficient tool to fight tuberculosis germs and other dangerous bugs.
