Human sweat peptides possess antibiotic properties

An antibiotics made of sweat can deal with hospital super bacteria like resistant lethal strains of tuberculosis, reports The Daily Mail. Human protein dermcidin (DCD) gets activated in a salty, moderately acidic environment, which is exactly what sweat is.


When activated, it is able to pass through the membrane of a pathogen cell eventually destroying it.


Using protein as a transport molecule, new effective drugs able to perforate any cell walls can be created.


Dr Ulrich Zachariae from the University of Edinburgh says: “There are about 1,700 natural antibiotics known to exist. While the spread of resistant to drugs pathogens remains a concerning problem, these findings could bring a real salvation”.


When our skin gets damaged, DCD is excreted by sweat glands. Along with other antimicrobial peptides it can quickly cleanse the wound of any bacteria and even fungi.


The research confirmed that the molecular structure of the protein is abnormally elongated, permeable and flexible. As a result it is capable to adapt to any type of cell membranes.


Dermcidin has proven to be effective against the acknowledged problematic infectious agents as Staphylococcus aureus and Mycobacterium tuberculosis.
