Cutting-edge diagnostics improve disease detection

New types of rapid testing  mastitis and bovine tuberculosis were among then topics discussed by experts at a recent meeting in Cambridge.

Currently animal health testing can take weeks of culturing in a laboratory or rely on an immune response as an indicator of disease, rather than detecting actual disease presence, scientists were told at the  Agri-Tech East Pollinator event on 13 February.

Agri-Tech East director Belinda Clarke said: “Speed is vital in effective disease management; if farmers and growers have access to cost-effective tools that are simple to use on-farm then they can take a range of preventative measures to pre-empt problems.

“Additionally if the tests show that there isn’t a problem this can mitigate unnecessary treatment.”

Rapid results

After a long wait for test results for one of her animals, Katie Cavanagh decided there was a need for a rapid handheld diagnostic test for mastitis – a disease that costs the UK cattle industry £41.8million a year.

By miniaturising a human diagnostic method, she has developed a handheld device that vets and farmers can use on-farm, to test milk and diagnose the condition. She is now seeking investment to bring the product to market.

“This technology already exists in human health,” explained Ms Cavanagh.

“We’re simply taking what they do in a microbiology lab and putting it onto printed circuit boards. It’s much more accessible and affordable. If you can diagnose quickly and accurately, you can treat more effectively and reduce yield loss as well as potential loss of the animal.”

Accurate tests

Rapid, accurate blood and milk tests for bovine TB and Johne’s disease – both of these chronic diseases are caused by mycobacteria and current tests have proved inadequate to control the diseases – with over 43,000 cattle slaughtered in the UK due to bovine TB in last year.

PBD Biotech has developed Actiphage Rapid, a biotechnology that can confirm the presence or absence of mycobacteria in blood or milk within six hours, enabling infected animals to be identified and isolated.

The milk test can also be used for quality assurance, to confirm that dairy products are free from mycobacteria. It has already been used on a Devon farm to help achieve TB-free status for the first time in six years.

PBD Biotech chief executive Berwyn Clarke said: “This is a huge achievement and provides a beacon of hope for farmers.

“Following this success, Actiphage has been included in the government’s protocol for Exceptional Private Use for chronic TB breakdowns in England. The test uses novel technology and we are involved in extensive international testing to meet regulatory requirements.”
