Horse dung has scientists on scent of antibiotic success

The key to creating the next generation of antibiotics could lie in horse dung. That's according to researchers at ETH Zurich and the University of Bonn who have produced copsin, an antibiotic protein compound, in the common inky cap mushroom that grows in manure. A new protein with antibiotic properties has been found in a mushroom that grows on horse dung. Researchers are now exploring the various potential applications.Microbiologists and molecular biologists at ETH Zurich and the University of Bonn have discovered a new agent in fungi that kills bacteria. The substance, known as copsin, has the same effect as traditional antibiotics, but belongs to a different class of biochemical substances. Copsin is a protein, whereas traditional antibiotics are often non-protein organic compounds. Copsin belongs to the group of defensins, a class of small proteins produced by many organisms to combat microorganisms that cause disease. The human body also produces defensins to protect itself against infections. They have been found, for example, on the skin and in the mucous membranes. story from science daily.
