The benefits of using medical-grade honey to treat and prevent infection in wounds has been confirmed by Sydney researchers.
Dr Nural Cokcetin tested more than 600 Australian honey samples and documented the antibacterial activity, which strongly corresponds to the levels of methylglyoxal (MGO), one of honey’s most active ingredients.
A large, star-shaped molecule is being harnessed by a University of Melbourne team to kill superbugs.
Professor Greg Qiao and his colleagues from the Melbourne School of Engineering have created a polymer that kills antibiotic-resistant bacteria by ripping apart their cell walls. Continue reading Using stars to overpower superbugs
Could your newly synthesised molecule kill a superbug? Matt Cooper can tell you.
His team is offering a free screening service for the world’s chemists to test their compounds against antibiotic-resistant bacteria, helping them to potentially find a new antibiotic that will fight the rise of these ‘superbugs’.
“We’re helping the community unlock the hidden value of these chemicals,” says Matt, whose team is from the Community for Open Antimicrobial Drug Discovery (CO-ADD), a not-for-profit, global initiative of The University of Queensland’s Institute for Molecular Bioscience. The screening began in February 2015, and Matt has already received thousands of samples from locations including India, Singapore, New Zealand, France, Israel, UK and the USA.
Kathryn Holt, of the University of Melbourne’s Bio21 Institute, used genome sequencing to discover that an epidemic of deadly typhoid bacteria in Nepal’s capital city was driven by climate, and not by the outbreak of novel genetic strains.
Her research, published in the Royal Society journal Open Biology, changes our understanding of how typhoid spreads and how we can better respond to other bacterial epidemics.
Elena Ivanova and her fellow researchers at Swinburne University of Technology were studying self-cleaning surfaces in nature when they discovered bacteria being killed on the wings of the clanger cicada, Psaltoda claripennis, a species mostly found in Queensland.
The secret seemed to lie in millions of tiny rounded spikes, or nanopillars, each a thousand times smaller than the width of a human hair.
