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.
Golden staph (Staphylococcus aureus) was thought to be a single, well-defined species—until a recent Darwin discovery showing that bacteria with golden staph characteristics are actually three distinct species.
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.
A typhoid outbreak in Kathmandu has provided new insights into bacterial epidemics and antibiotic resistance, thanks to a Melbourne scientist’s genomic research.
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.
Nanoscale spikes on dragonfly wings are inspiring materials that kill bacteria, including deadly antibiotic-resistant golden staph (Staphylococcus aureus).
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.
