上个世纪，世界各地出现的新疾病越来越多，导致生物多样性永久性丧失。柏金丝寄生是一种微真核寄生门，由寄生原生生物的四个主要谱系组成，寄主范围广泛。其中一些因其地理入侵能力和致病性（导致死亡事件）而构成重大的生态和经济威胁。在海洋环境中，目前描述了三个谱系，Parviluciferaceae， Perkinsidae和Xcellidae，分别感染鞭毛动物，软体动物和鱼类。相比之下，在淡水环境中只有一种谱系被正式描述：感染青蛙蝌蚪的严重珀金西感染因子。高通量测序方法的出现，主要基于18S rRNA测定，表明Perkinsea比之前描述的四个谱系更加多样化，特别是在淡水环境中。事实上，一些谱系可能是绿色微藻的寄生虫，但需要探索这种相互作用的正式性质。因此，到目前为止，大多数新描述的水生群集仅根据其环境序列来定义，并且仍然没有（尚未）与任何宿主相关联。这个微生物黑箱的揭示提出了许多研究挑战，以了解它们的生态作用，并最终防止它们最负面的影响。本文综述了金丝桃的生物学和生态学特性——多样性、生命周期、寄主偏好、致病性，并强调了其多样性和普遍性与广泛寄主的关系。
The last century has witnessed an increasing rate of new disease emergence across the world leading to permanent loss of biodiversity. Perkinsea is a microeukaryotic parasitic phylum composed of four main lineages of parasitic protists with broad host ranges. Some of them represent major ecological and economical threats because of their geographically invasive ability and pathogenicity (leading to mortality events). In marine environments, three lineages are currently described, the Parviluciferaceae, the Perkinsidae, and the Xcellidae, infecting, respectively, dinoflagellates, mollusks, and fish. In contrast, only one lineage is officially described in freshwater environments: the severe Perkinsea infectious agent infecting frog tadpoles. The advent of high-throughput sequencing methods, mainly based on 18S rRNA assays, showed that Perkinsea is far more diverse than the previously four described lineages especially in freshwater environments. Indeed, some lineages could be parasites of green microalgae, but a formal nature of the interaction needs to be explored. Hence, to date, most of the newly described aquatic clusters are only defined by their environmental sequences and are still not (yet) associated with any host. The unveiling of this microbial black box presents a multitude of research challenges to understand their ecological roles and ultimately to prevent their most negative impacts. This review summarizes the biological and ecological traits of Perkinsea—their diversity, life cycle, host preferences, pathogenicity, and highlights their diversity and ubiquity in association with a wide range of hosts.
