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. Their results could contribute to the development of new antibiotics that control multi-resistant bacteria. Scientists from the University of Edinburgh and from Goettingen, Tuebingen and Strasbourg have uncovered the atomic structure of the compound, enabling them to pinpoint for the first time what makes dermcidin such an efficient weapon in the battle against dangerous bugs. Although about 1700 types of these natural antibiotics are known to exist, scientists did not...
