Enzybiotics: A look to the future, recalling the past

The discovery and development of antibiotics was one of the greatest successes of Medicine in the 20th century and allowed the control of many diseases caused by microorganisms. Nevertheless, it is necessary to search constantly for new therapeutic tools in the continuing fight against disease-causing microorganisms and this probably leads us to today's concept of enzybiotics. Although microorganism-degrading enzymes have been known since the beginning of the last century, their use was soon forgotten because of the widespread use of antibiotics. The term enzybiotic is a hybrid word from enzyme and antibiotic and refers to phages: that is, viruses that attack and lyse bacteria and that can potentially help us to fight bacterial diseases. If the concept of enzybiotic is extended to antifungal enzymes, an enormous potential in the struggle against microorganism-due diseases may become available in the foreseeable future.
