In any small practice, there’s a risk that an error can be interpreted as a one-off event, as there is limited awareness that the same incident could be occurring in other practices.
Natural phenols, such as those found in chocolate, and minerals such as iron are being used to develop fast, economical drug-delivery capsules.
Frank Caruso and his team at The University of Melbourne are making nano-sized capsules that will encase vaccines and protect them from being broken down when entering the body. They believe that this delivery system will be biologically friendly and overcome a major challenge for medical materials: their compatibility with living systems.
One of the challenges of treating diseases such as cancer and HIV is delivering treatment with minimal damage to healthy areas.
The world’s meat production could be lifted by 10 to 15 per cent if a vaccine can be found to combat the liver fluke.
This is the aim of a collaborative bioscience group at the new $288 million Centre for AgriBioscience (AgriBio).
An effective vaccine against liver fluke could not only boost meat production but would also lead to a large reduction in the amount of drugs given to livestock, says Prof Terry Spithill, who is co-director of AgriBio and based at La Trobe University.

Four of Australia’s most accomplished scientists have been elected to the oldest scientific academy in continuous existence, the Royal Society of London.
Prof Ian Frazer, Prof Alan Cowman, Prof Mark Randolph and Dr Patrick Tam join 40 other scientists to be elected to the Royal Society in 2011, which celebrated its 350th anniversary last year.
The first Australian trials have started of a vaccine to prevent koalas from contracting and spreading the deadly sexually transmitted disease, chlamydia.
The trials—supervised by Prof Peter Timms and Prof Ken Beagley from Queensland University of Technology (QUT)’s Institute of Health and Biomedical Innovation—have been undertaken safely both in healthy koalas and koalas that already have chlamydial disease. All vaccinated koalas developed a good immune response to the anti-chlamydia vaccine, which shows great promise of making a significant impact on the disease in the near future.
Chlamydia is a major threat to the continued survival of koalas. Almost all populations in Australia are affected by the disease. It is a significant cause of infertility, urinary tract infections, and inflammation in the lining of the eye which often leads to blindness.
Koala numbers are declining across virtually its whole range. In the Koala Coast region of southeast Queensland in 2008 it was estimated that 2332 koalas had been lost in a three-year monitoring period. That represented a 51 per cent decrease.
By studying chlamydial disease in koalas, QUT researchers hope to understand the condition better in general. They believe their work may also hold the key to developing a successful vaccine for use against the human sexually transmitted disease Chlamydia trachomatis, a major cause of infertility in women.

VESKI’s main initiative – to return successful Australian expatriates with outstanding skills in science, technology and design – is paying off with some inspiring work.
In 2004, VESKI’s – Victorian Endowment for Science, Knowledge and Innovation – inaugural Fellow Professor Andrew Holmes returned from Cambridge University to work in a new $100 million Bio21 Molecular Biology and Biotechnology Institute. One of the most important research areas to emerge since has been the development of cheap plastic solar cells.
VESKI – Victorian Endowment for Science, Knowledge and Innovation – has awarded its latest Innovative Fellowships to two outstanding woman scientists.
VESKI was established with a $10 million endowment from the Victorian Government to entice talented expatriates home.
A new oral vaccine against shellfish allergies is being developed by researchers at RMIT University.
Assoc. Prof. Andreas Lopata and his team in RMIT’s School of Applied Sciences are working to help find a different method for vaccination against the potentially deadly allergy.
Diseases such as leptospirosis, fowl cholera, bovine respiratory diseases or footrot in sheep have devastating impacts on livestock industries worldwide. They have a debilitating effect on animals, leading to food shortage and major economic losses.
In July 2009, the Australian Government responded to urgent global calls to use the Southern Hemisphere’s flu season as a catalyst for investigating the severity and global threat of the H1N1 flu strain.
