Blue tongue serotype-3 in cattle: clinical signs, pathology, and current status


On Tuesday, September 5, 2023, blue tongue (BT) was detected in the Netherlands. A few days later, Wageningen Bioveterinary Research (WBVR) announced that, based on whole genome sequencing, serotype 3 (BTV-3; genus Orbivirus, family Reoviridae) was identified. This finding was later confirmed by the European reference laboratory in Spain.

Blue tongue is a viral disease in ruminants transmitted by various Culicoides species. As BTV-3 spreads across the Netherlands, and cases have been confirmed in Germany, Belgium, and the United Kingdom, the clinical signs of the BTV-3 outbreak in cattle are becoming increasingly clear. The impact of this BTV-3 outbreak in cattle is currently being further investigated by GD. You can also read the article in the highlights report ruminants of December 2023
