New diagnostic tool against footrot

Friday 17 November 2017

Cutting edge technology is set to speed up the detection of footrot with a statewide 12 month field trial by PIRSA Biosecurity SA.


Lamp medicated isothermal amplification or LAMP, is a diagnostic process using a single tube technique for the amplification of DNA. A portable diagnostic technology, it can provide results on the farm within minutes.

As part of the trial Biosecurity SA Animal Health officers will compare the LAMP process to other existing disease diagnosis technologies.

Footrot is a notifiable disease and must be reported immediately, for information on detecting, controlling and reporting footrot visit www.pir.sa.gov.au/biosecurity/animal_health/sheep/health/footrot

A video explaining the LAMP process is available at https://youtu.be/N4qS73UmUOI

Background

LAMP is an on-farm test and able to provide a diagnosis within 20 to 30 minutes while the results from the currently available laboratory test processes can take several weeks.

The trial is occurring in collaboration with AgriBio, the diagnostic arm of Agriculture Victoria, the latter assisting with test calibration and diagnostic reagents. A number of PIRSA Animal Health staff have been trained in the use of the LAMP machines.

In addition to footrot, LAMP can also be used for other animal and plant disease detection, depending on the availability of suitable reagents.

Quotes attributable to Chief Veterinary Officer, Roger Paskin

LAMP is the technology of the future. Its rapidity and the fact that it can clearly be shown to the producer will improve our diagnostic outcomes, particularly for the footrot management program in the first instance.

While this trial focusses on footrot we are hoping to eventually expand LAMP use toward detecting other animal health diseases. In doing so we believe this technology will provide the South Australian livestock industry an opportunity to provide greater clarity in disease rule outs to our trading partners.
