Abstract：
Colpodella species are close relatives of Apicomplexan protozoa. Although most species of this genus are free-living organisms that feed on other protists and algae, reports indicate their occurence in ticks and human patients, including an individual with a history of tick bite manifesting neurological symptoms. During an investigation of tick-borne pathogens (TBPs) in blood samples of cattle, goats, and in ticks collected on them, Colpodella sp. DNA was detected in a Rhipicephalus bursa tick collected from cattle, while of Theileria sergenti/buffeli/orientalis, Babesia bigemina, Sarcocystis cruzi, Babesia spp., and Rickettsia spp. were molecularly detected in cattle, goats, and ticks in southern Italy. Data herein reported highlight the unprecedented presence of Colpodella sp. in ticks in Italy, raising concern due to the potential pathogenic role of this less known protozoan. This finding advocates for performing routine epidemiological surveys to monitor potential emerging vector-borne pathogens.
摘要：
Colpodella物种是顶plex原生动物的近亲。尽管该属的大多数物种是以其他原生生物和藻类为食的自由生物，报告显示它们发生在蜱和人类患者中，包括有蜱虫咬伤史表现出神经症状的人。在对牛血液样本中的蜱传病原体（TBP）进行调查期间，山羊,在它们身上收集的蜱虫中，Colpodellasp.在从牛收集的rypicephalusbursatick中检测到DNA，在塞里利亚·谢尔根蒂/布夫利/东方的时候，babesiabigemina,Cruzi结节虫,巴贝西亚。,和立克次体。在牛中被分子检测到，山羊,和意大利南部的蜱虫。本文报道的数据突出了Colpodellasp的空前存在。在意大利的蜱，由于这种鲜为人知的原生动物的潜在致病作用，引起了人们的关注。这一发现提倡进行常规流行病学调查，以监测潜在的新兴媒介传播病原体。
