Summary
Staphylococcus aureus (Golden staph) has been termed a "superbug" because of its persistent ability to acquire resistance to a wide range of antibiotics. Once considered primarily a hospital-acquired pathogen, many patients are now being infected with antibiotic-resistant Golden staph outside of hospitals. The primary aim of this research program is to develop new antibiotics to treat antibiotic-resistant strains of Staphylococcus aureus and related pathogens.

Since their discovery antibiotics have had a profound effect on the health and well being of mankind, providing ready effective treatment for otherwise intractable infections. Although pencillin was initially effective against a large range of infections by the 1950s it was apparent that some bacterial strains had become resistant to this antibiotic. Partially in response to this resistance new antibiotics such as streptomycin, chloramphenicol and tetracycline were developed. These new drugs were potent against both Gram-positive and Gram-negative bacteria. However, there were early signs that resistance to these drugs was also emerging. For example, in 1953, during a Shigella outbreak in Japan, a strain of the dysentery bacillus was isolated which was multi-drug resistant, exhibiting resistance to chloramphenicol, tetracycline, streptomycin and the sulfanilamides. Multidrug-resistance in pathogenic strains of bacteria has in the last decade presented an increasing problem in treatment of bacterial infections and diseases. In 1994 a Melbourne public hospital reported a new antibiotic resistant strain of bacteria. This bacterium was resistant to vancomycin (the antibiotic used when all others have failed) and is known as VRE or vancomycin resistant enterococcus. Now strains of golden staph resistant to all antibiotics have appeared. The re-emergence of tuberculosis (TB), which kills more than 3 million people annually and which is spreading rapidly throughout the world, is also a serious threat, particularly as many strains are now multi-drug resistant. New antibiotics are needed that overcome bacterial drug resistance. It is anticipated that this research will lead to new antibiotics by exploiting molecular components of bacteria that have only recently been identified.Read moreRead less

Summary
Osteoarthritis is the most common form of arthritis and commonly affects the hand hip and knee in older Australians with an annual cost of around 4 billion dollars. This study will lead to a greater understanding of the role of factors influencing the development and progression of osteoarthritis of the knee by utilising a novel magnetic resonance imaging technique. In particular, it will focus on the role of physical activity and bone underlying the cartilage.

This study will lead to a greater understanding of the role of factors influencing the development and progression of osteoarthritis of the knee by utilising a novel magnetic resonance imaging technique. In particular, it will focus on the role of physical activity and bone underlying the cartilage. If associations are discovered, accurate public health messages regarding prevention can then be developed.Read moreRead less
LMO2-containing Complexes In Leukemia And Blood Cell Development

Summary
Childhood T-cell leukemias have a poor prognosis for recovery. We are determining, with atomic level precision, how the proteins Lmo2 (also linked to prostate and other cancers) and Tal1, and their binding partners contribute to both normal blood cell development and T-cell leukemia. With this information we are developing reagents that can be used to disrupt disease-causing complexes, and which will lead towards the development of new, specific, therapeutics for leukemias and other cancers.
