First quarter of 2018 sees record diagnostic rate of pig virus ‘PRRS’

Jul 23, 2018

The first quarter of 2018 saw the highest ever recorded diagnostic rate of the pig virus porcine reproductive and respiratory syndrome (PRRS), latest figures show. According to the Animal Plant and Health Agency’s (APHA) GB Emerging Threats Quarterly Report, the virus has increased to record levels. It shows that the first quarter of 2018 was the highest recorded quarterly diagnostic rate (16.6%) with the previous highest being in Q4 2016 (12.7%). PRRS is an economically important disease which causes reproductive failure in breeding stock and respiratory tract illness in young pigs. The seasonality pattern with a peak in diagnoses in winter months and dip in summer months is familiar, according to the National Pig Association (NPA). The pig industry body said that the data supports anecdotal reports from pig practitioners of continued clinical problems associated with PRRS. “The rise may well reflect better survival and transmission of the virus in cooler, darker and less dry weather conditions, as well as colder wetter weather making effective cleaning and disinfection harder to... ...

New instruments for Johne’s disease and tuberculosis

Jan 8, 2018

Two prototype instruments to diagnose Johne’s disease in cattle and tuberculosis in humans and cattle have been successfully developed by Epigem. The news follows the completion of two Innovate UK-funded projects, MilkEd and MIMIC. The micro-engineering company says that it is now focussed on preparing the instruments for extensive operational trials. “We have made great strides technically in manufacturing devices to detect Johne’s disease in cattle and TB in humans,” said Epigem’s managing director Tim Ryan. “Complex problems require excellent multi-disciplinary teamwork, and these projects confirm that.” MilkED The MilkEd project aimed to develop an instrument that could identify Johne’s disease in under 45 minutes. It was crucial that the instrument could work both on-farm and in the laboratory. The prototype uses surface acoustic waves to control an assay that is packaged into a disposable cassette. The cassette is fully automated and interconnects in a ‘plug and play’ manner within a boxed data reader. The portable reader consists of integrated miniature sub-assemblies that perform electro-opticals microfluidic and microelectronic functions. Operated... ...
