LES INSECTES : UNE MERVEILLEUSE SOURCE D'ANTIBIOTIQUES © Dung Vo Trung
-
 
There is a good chance tomorrow's drugs are currently crawling quietly about their business in the undergrowth. For years scientists have been intrigued by an apparent paradox: how do insects manage to survive in an environment where fungi and bacteria are particularly abundant ? The fruit fly, for instance, is remarkably resistant to both fungi and bacteria. It has long been known that insects have a highly efficient spontaneous immune system: anti‑microbial peptides. These peptides are only secreted in the presence of harmful bacteria. Insects share their spontaneous immune system with mammals, it acts as a "frontline intervention" before the particular entity develops antibodies.
