Bison bonasus is an indigenous species of Central and Eastern Europe with the largest wild population inhabiting Białowieża Primeval Forest; however, free‐living and captive European bison are reared in many countries around the world. Despite that the European bison was rescued from the extinction after the First World War, it remains as endangered species. Changing environment as well as human activity...
The detection of Schmallenberg virus (SBV) in the breeding bull semen raised the question of the possibility of venereal transmission of SBV which could result in cost-intensive restrictions in the trade of bovine semen. In order to evaluate the presence of SBV RNA in bovine semen, 131 bull semen samples from four locations in Poland collected between 2013 and 2015 were analysed by RT-PCR for viral...
The Schmallenberg virus (SBV), as a new for Europe Ortobuniaviridae genus member, emerged in Poland in 2012, spreading rapidly across the country. Serological monitoring revealed a continuous increase of seropositivity among farm ruminants; moreover, the virus was detected in the insect vector, i.e. biting midges in different regions. The sylvatic cycle of SBV infections cannot be ruled out due to...
The study presents the analysis of the findings of 234 post-mortem examinations on free-ranging and captive European bison selectively culled or having fallen between 2008 and 2013 in Białowieża Primeval Forest. Pneumonia, emphysema, nephritis, bodily traumas, and intestinal lesions were observed in 106 (45.3%), 77 (32.9%), 82 (35.0%), 68 (29.1%), and 56 (23.9%) animals respectively and were the most...
The aim of the study was to evaluate the prevalence of Schmallenberg virus (SBV) specific antibodies in ruminants from 13 Polish provinces, sampled between January 2010 and August 2013. A total number of 1813 serum samples from cattle, sheep, goats, mouflon, wild and farmed cervids, and European bison were tested by ELISA for viral nucleoprotein antibodies. First SBV seropositive animals were identified...
