Using a face mask, Adelaide researchers have a new way to detect a major hidden equine health issue.
Up to 80 percent of horses – including racehorses and showjumpers – suffer from a form of asthma that affects their performance and wellbeing.
Researchers led by veterinarian Surita Du Preez from the University of Adelaide are designing a way to detect the condition – which often produces no obvious symptoms – without adding further stress to the affected animals.
“Currently the methods that are available to diagnose the mild to moderate form of horse asthma are invasive,” says Surita.
Melbourne veterinary researchers are using genomic techniques and bioinformatics to lead them to new specific candidate drugs for the treatment of a devastating parasite known as barber’s pole worm, which causes anaemia, deaths and massive production losses in the sheep industry.
Using the latest gene sequencing technology and the supercomputers of the Victorian Life Sciences Computation Initiative, Prof Robin Gasser’s research group from the University of Melbourne’s Veterinary School have been able to compare barber’s pole worm’s DNA and RNA with that of other organisms in order to track down genes essential to the worm’s growth, development, reproduction and survival.

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.

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.
