First antibiotic produced by bacterium in the human body

Lugdunin is an antibiotic that can be produced by a bacterium (Staphylococcus lugdunensis) present in the human nose – as discovered by researchers from Tubingen University, Germany, in July 2016. Antibiotics are compounds that can inhibit the growth of bacteria or even kill them. They are now regarded as essential for human health and well-being, since some infections caused by bacteria are lethal. In recent years, some bacteria (so called “superbugs”) have developed resistance to standard antibiotics. Because of this, scientists have been looking for new and alternative antibiotics. Lugdunin is active against several bacteria (Gram-positive class), including MRSA (Methicillin Resistant Staphylococcus aureus) – one of the antibiotic-resistant bacteria.
