First Detection of Bluetongue Virus Type 3 in Poland in 2024-A Case Study in European Bison (<i>Bison bonasus</i>).

ABSTRACT: Since the emergence of serotype BTV-3, another bluetongue virus, in fall 2023, this variant has been causing great losses in livestock farming in Europe. The virus spreads faster than the epidemic BTV-8, which appeared on the continent nine years earlier. This study describes the first case of BTV-3 in Poland detected in a European bison (Bison bonasus) in Poland's Wolin National Park, approximately 15 km from the German-Polish border. The animal suffered from a severe and fatal hemorrhagic disease. The symptoms included respiratory problems, bloody diarrhea, and rapidly progressive cachexia. In addition to the virus's confirmation as BTV-3 and the presence of the infecting agent in the blood and spleen of the animal, the virus was also detected in one pool of blood-fed Culicoide
