Date Time Tree resin could cure infections caused by MRSA bacteria Currently, MRSA is one of the fastest evolving bacteria, causing a wide range of infections from skin disease to serious endocarditis. Researchers at the University of Helsinki created a new biopolymer which kills MRSA nearly 100% upon contact, by combining nanocellulose with compounds derived from tree resin, a side stream from forest industry. Methicillin-resistant S. aureus (MRSA) is any strain of S. aureus that has developed resistance towards the broad-spectrum β-lactam antibiotics such as cloxacillin, methicillin and flucloxacillin. Various sequelae can result from MRSA infection such as chronic wound infection, sepsis or ventilator-associated pneumonia. MRSA is the leading cause of chronic infections associated to the use of indwelling medical devices.
