From a herd of captive reindeer (Rangifer tarandus tarandus) consisting of two males and seven females with five calves, three calves were diagnosed on post mortem examination with a Babesia capreoli infection. The diagnosis was indicated by PCR and when the other reindeer were examined two adult females and a one-year-old male were Babesia-positive. Molecular characterization of the 18S rDNA of the parasite showed complete identity with known B. capreoli sequences. Ixodes ricinus has been demonstrated to be a competent vector for B. capreoli from infected roe deer (Capreolus capreolus), the natural host of B. capreoli. The B. capreoli infection in these reindeer may have been transmitted by infected ticks (Ixodes ricinus) originating from roe deer living in the forest and meadows surrounding the enclosure.
在一群圈养的驯鹿(Rangifer tarandus tarandus)中,有两只雄性、七只雌性和五只幼崽,在尸检时发现三只幼崽感染了巴贝斯虫(Babesia capreoli)。通过聚合酶链反应(PCR)确诊了该感染,对其他驯鹿检查时发现两只成年雌性和一只一岁雄性的巴贝斯虫检测呈阳性。对该寄生虫的18S核糖体DNA(rDNA)进行分子特征分析,结果显示与已知的巴贝斯虫序列完全一致。蓖麻硬蜱(Ixodes ricinus)已被证明是巴贝斯虫从受感染的狍(Capreolus capreolus)(巴贝斯虫的自然宿主)传播的有效媒介。这些驯鹿身上的巴贝斯虫感染可能是由生活在围栏周围森林和草地中的狍身上感染的蜱(蓖麻硬蜱)传播而来的。
