The American bison () is the largest terrestrial mammal of North America, with around 350,000 individuals in the wild and in private herds but the knowledge regarding the presence of different vector-borne pathigens in these mammals is very poor. and spp. are tick-borne apicomplexan parasites which are considered to be among the most commonly found blood parasites of large ruminants, often with a high economic importance. However, the knowledge on piroplasms of bisons is extremely scarce. The aim of our study was to evaluate the presence of apicomplexan parasites in blood and tissues of farmed American bison from Romania. Overall, we tested 222 blood samples and 11 tissues samples (heart, liver, and spleen) from farmed raised for meat in Romania. All the samples were analyzed by nPCR targeting the gene for piroplasmids. All positive samples were sequenced and analyzed phylogenetically. The overall prevalence of infection with piroplasmids in American bison was 1.65%, with and sp. identified following sequencing. To our knowledge, this is the first report of piroplasms detected in blood and tissues of farmed from Europe. Further studies are necessary in order to obtain a better overview on the epidemiological status and clinical relevance of piroplasms in farmed American bisons.
美洲野牛（）是北美洲最大的陆生哺乳动物，野生和私人畜群中约有35万头，但对于这些哺乳动物中不同媒介传播病原体的存在情况了解甚少。和属是蜱传播的顶复门寄生虫，被认为是大型反刍动物中最常见的血液寄生虫之一，通常具有很高的经济重要性。然而，关于野牛梨形虫的知识极其匮乏。我们研究的目的是评估罗马尼亚养殖的美洲野牛血液和组织中顶复门寄生虫的存在情况。总体而言，我们检测了罗马尼亚养殖用于肉类生产的222份血液样本和11份组织样本（心脏、肝脏和脾脏）。所有样本通过针对梨形虫基因的巢式聚合酶链反应（nPCR）进行分析。所有阳性样本均进行测序并进行系统发育分析。美洲野牛中梨形虫感染的总体患病率为1.65%，测序后鉴定出和属。据我们所知，这是欧洲养殖的美洲野牛血液和组织中检测到梨形虫的首次报告。有必要进行进一步研究，以便更好地了解养殖美洲野牛中梨形虫的流行病学状况和临床相关性。
