Preventing Infectious Swine Disease Spread With Field-based Portable Device

Preventing Infectious Swine Disease Spread With Field-based Portable Device

By Cordis

The impact of swine diseases and other livestock disease outbreaks extends beyond animal sickness and mortality in a highly interconnected world, causing major problems. Following the initial disease outbreak, laboratory confirmation of the aetiologic infectious agent can take several weeks or even months. Hence, the development of rapid and accurate diagnostic methods is crucial for achieving effective infectious disease control and limiting severe biophysical and socioeconomic effects. The EU-funded SWINOSTICS project has been addressing this challenge and building a portable diagnostic device to detect swine viral diseases in just a few minutes.

The tool is focused on six viruses: African swine fever virus, porcine reproductive and respiratory syndrome virus, swine influenza virus—H1N1 strain, porcine parvovirus, porcine circovirus, and classical swine fever virus. "The device will use swine oral fluid samples as its main input, even though, it will be compatible with the use of other types of samples, such as feces, blood or nasal swabs," as noted on the project website. "The use of oral fluids as the main input diminishes the time needed for the analysis and simplifies the sample collection, allowing also the collection of wild boar samples."

The diagnostic device developed by SWINOSTICS partners uses advanced biosensing and photonics technologies to tackle emerging and endemic viruses causing epidemics in pig farms in Europe. It will enable "immediate threat assessment at the farm level, with the analytical quality of commercial and institutional laboratories," as stated on the project website. "The device will be portable and will provide results in less than 15 minutes for 4-5 samples simultaneously, making it highly suitable for use in the field. The modular construction of the device would allow future upgrades to increase capacity if so desired."

Over two years into its field diagnostics project targeting the swine industry, the SWINOSTICS team has completed the first integration testing phase, according to a news item. "The scope of this has been to verify that all device modules operate flawlessly in combination with each other and to fix various issues that could affect overall device functionality."
