An Institute for Molecular Bioscience researcher has received a prestigious new national fellowship to support her research into an alternative to antibiotics.

Professor Jenny Martin was one of only 15 Australian Research Council (ARC) Laureate Fellows selected from a nationwide field of 148, and the only fellow currently working in Queensland.

She received one of two fellowships awarded to The University of Queensland. The other, to Professor Peter Mumby of the United Kingdom, is the sole expert to be attracted to Australia under the ‘foreign nationals' category of this scheme. He will investigate improving coral reef management.

Each successful Fellow will receive a major package of grant support, with average funding exceeding $2.7 million over five years.

Professor Martin will aim her fellowship at developing a new class of antibacterial drugs that may avoid the problems of antibiotic resistance.

Antibiotics were one of medicine's most significant breakthroughs, but their usefulness has been undermined as bacteria develop resistance to them.

“The lack of drugs effective against some disease-causing bacteria is shaping as a potential crisis,” Professor Martin said.

“Bacteria develop resistance because antibiotics work by killing most bacteria, leaving only the resistant bacteria alive.

“My research will address this by developing compounds that won't kill bacteria, but rather will inactivate a specific bacterial machinery responsible for causing disease.”

She said bacteria cause disease by producing molecules called virulence factors, which require a type of chemical bond, disulfide bonds, to function.

Professor Martin will develop drugs that target the bacterial machinery that triggers the insertion of disulfide bonds into virulence factors.

“Infectious bacteria with mutations in their disulfide bond machinery are incapable of causing disease, highlighting the importance of this machinery in bacterial virulence, and the potential to develop an entirely new class of antibacterials that may avoid bacterial resistance mechanisms,” she said.

UQ Vice-Chancellor, Professor Paul Greenfield, congratulated Professors Martin and Mumby.

“These new Australian Research Council awards, which evolved from the former Federation Fellowships, will build the next generation of research capability in our nation, and allow early-career researchers at UQ to work alongside internationally renowned Laureates,” Professor Greenfield said.

“This will enhance UQ's strong research training environment, and add to Australia's current and future stature in the international research race.”
