The European bison (Bison bonasus) is a near threatened species and requires health monitoring. The aim of the present study was to determine the prevalence of antibodies to pathogens known to cause respiratory and digestive illness in ruminants.
In the studied 328 European bison, the highest seroprevalence was observed for Bovine herpesvirus-1 (BoHV-1) (50.27%), Bovine Coronavirus (BCoV) (26.36%), and Bluetongue Virus (BTV) (12.83%). For Mycoplasma bovis strains and Bovine Viral Diarrhea Virus (BVDV), positive results were rare. Interestingly, a higher prevalence of BTV antibodies was noted in the northeastern populations and older animals.
Our findings indicate that the Polish European bison population appears to have considerable contact with BoHV-1; however, this does not appear to be of great significance, as clinical symptoms and post-mortem lesions are rarely noted in Polish European bison population. The high seroprevalence of BTV in the north-east of Poland is an ongoing trend, also noted in previous studies. It is possible that European bison may perpetuate the virus in this region. This is the first report of antibodies for BCoV in European bison.
欧洲野牛（Bison bonasus）是一种近危物种，需要进行健康监测。本研究的目的是确定引起反刍动物呼吸道和消化道疾病的病原体的抗体流行率。
在所研究的 328 头欧洲野牛中，牛疱疹病毒 1（BoHV-1）（50.27%）、牛冠状病毒（BCoV）（26.36%）和蓝舌病病毒（BTV）（12.83%）的血清阳性率最高。牛支原体菌株和牛病毒性腹泻病毒（BVDV）的阳性结果则较为罕见。有趣的是，东北部种群和老年动物的 BTV 抗体阳性率更高。
我们的研究结果表明，波兰欧洲野牛种群与 BoHV-1 有相当大的接触，但这似乎并不重要，因为在波兰欧洲野牛种群中很少观察到临床症状和死后病变。波兰东北部 BTV 的高血清阳性率是一个持续的趋势，在之前的研究中也有报道。欧洲野牛可能在该地区传播该病毒。这是首次在欧洲野牛中检测到 BCoV 抗体。
