Ongoing Bluetongue Virus Outbreaks in Europe

22 November 2016

EU - Bluetongue Virus (BTV) continues to be a problem in Europe, with France reporting more than 90 outbreaks in the last few weeks, according to Sandrine Moine, PhD, R&D Manager at Thermo Fisher Scientific. Diagnostic tests can quickly and reliably identify the virus and help veterinarians contain the disease.

"Diagnostics played a key role helping establish the BTV restriction zones now in place in 14 EU countries, which helps contain the disease," said Dr Moine.

Since BTV is spread primarily by Culicoides biting midges, periods of warm weather are the most favourable times for disease transmission. The mild, midge-friendly winter may help spread the disease.

In ruminants, BTV can cause abortions, malformed foetuses and even death. Visual identification of BTV can be challenging since clinical signs in cattle, when seen, are similar to symptoms of other diseases. Infected cows without clinical signs may be an invisible source of BTV within a herd or region.

Thermo Fisher's polymerase chain reaction (PCR) and ELISA detection kits that have been validated with the Pirbright Institute, an OIE reference lab for BTV, can quickly and reliably identify whether BTV is present and, if so, which strain is involved. Many European countries are establishing surveillance and management programmes to help veterinarians and farmers battle BTV when detected.

Containing BTV

"We have been involved in the French surveillance program since 2007 and when the outbreak occurred in France last year, Thermo Fisher Scientific reacted quickly by meeting the increased demand for BTV diagnostic tools and working closely with French animal health experts to contain the disease, especially as vaccine availability was limited," she said. "It is part of our company’s mission to strive to be reliable partners in managing animal health issues with our large portfolio of ready-to-use diagnostic tools."

While the availability of a BTV vaccine varies by country, your veterinarian can help you make an informed decision on whether vaccination makes sense based on your own farm’s business risk and the diagnostic test results in your region.

So, if you suspect BTV in your herd, set up an appointment with your veterinarian and remain vigilant for bluetongue in your herd, she said.
