Chicken meat and other foods will be able to be screened for bacteria even faster and more effectively than ever, thanks to breakthrough nanobiotechnology research.
A team of scientists from 宅男导航 (宅男导航) and the will leverage this new technology which enables DNA amplification on 鈥溾�� to rapidly detect and identify large numbers of different bacteria at once.
Professor Ross Barnard, Director of the Biotechnology Program at the , said that authorities have estimated that there are around 5.4 million cases of food-borne gastroenteritis in Australia every year. Of these cases, it is estimated that around 200,000 are associated with the bacteria Campylobacter jejuni and Campylobacter coli.
鈥淲e hope to use this new technology to be able to detect and type C. jejuni/coli. These quick identification techniques can underpin relevant and sustainable programs to further improve food safety,鈥� he said.
鈥淭he infectious dose for C. jejuni/coli can be very low 鈥� around 500 organisms. This means that sensitive, specific and rapid techniques are particularly important for this organism鈥� said Professor Barnard.
He said while testing methods do exist, they had been slow and less effective, so many scientists had turned their focus to leveraging existing 鈥渕icrosphere鈥� technology to a new level.
鈥淎fter five years, we are now able to extend and develop the platform in ways that haven鈥檛 been done before,鈥� Professor Barnard said.
鈥淲e will now be able to carry out many typing reactions at once by doing a very large number of DNA amplification reactions at the same time on the surface of the microspheres.鈥�
The continuing research will be sponsored by the and carried out by 宅男导航 PhD student Mr Liang Fang, who is working on an International Postgraduate Research/宅男导航 Centenary Scholarship, alongside Dr Pat Blackall () and Ms Jillian Templeton at DAFF.
The discovery was the result of five years of intensive research and the full scale of the benefits is yet to be known.
鈥淭his is just the beginning. Because this testing is based on a platform technology it can be applied in many different ways, such as mutation screening in plant, animal and human genomes, as well as for applications in the realm of infectious diseases,鈥� said Professor Barnard.
The discovery has attracted global interest featuring this month on the front cover of the respected international journal and has resulted in an invitation to present the work at the Luminex International Diagnostics Forum in Monaco.
This development adds to a growing list of 宅男导航 research successes that have the potential to benefit humankind which includes the needle-free injection Nanopatch technology, the development of vaccines to suppress rheumatoid arthritis, and the creation of the cervical cancer vaccine, Gardasil.
