Insect Antibiotic Provides New Way to Eliminate Bacteria

16-Nov-2018

An antibiotic called thanatin attacks the way the outer membrane of Gram-negative bacteria is built. Researchers at the University of Zurich have now found out that this happens through a previously unknown mechanism. Thanatin, produced naturally by the spined soldier bug, can therefore be used ...
