克氏锥虫支系是由克氏锥虫及其近亲组成的一组寄生虫。虽然有几个物种在系统发育上被证实属于这个分支，但还不确定还有多少物种可以被认为属于这个群体。本文报道了巴拿马运河区蝙蝠牙买加Artibeus jamaicensis的锥虫寄生虫的调查结果，该寄生虫是重要的种子传播者。利用泊松树过程（Poisson tree process， PTP）方法，我们初步鉴定了5种锥虫，它们都属于克氏锥虫支系。一个由三个假定的锥虫物种组成的单系小群位于进化枝系统发育的基础，为这些寄生虫进入新大陆的至少五次独立殖民事件提供了证据。Artibeus jamaicensis提出了一种高这些血液寄生虫和脊椎动物的多样性最高的假定的锥体虫物种的数量报告从一个位置。我们的结果强调需要继续努力调查哺乳动物锥虫。
The Trypanosoma cruzi clade is a group of parasites that comprises T. cruzi sensu lato and its closest relatives. Although several species have been confirmed phylogenetically to belong to this clade, it is uncertain how many more species can be expected to belong into this group. Here, we present the results of a survey of trypanosome parasites of the bat Artibeus jamaicensis from the Panama Canal Zone, an important seed disperser. Using a genealogical species delimitation approach, the Poisson tree processes (PTP), we tentatively identified five species of trypanosomes - all belonging to the T. cruzi clade. A small monophyletic group of three putative Trypanosoma species places at the base of the clade phylogeny, providing evidence for at least five independent colonization events of these parasites into the New World. Artibeus jamaicensis presents a high diversity of these blood parasites and is the vertebrate with the highest number of putative trypanosome species reported from a single locality. Our results emphasize the need for continued efforts to survey mammalian trypanosomes.
