Abstract

Tick-borne Apicomplexa encompass a group of parasites responsible for significant medical and veterinary diseases, including babesiosis, theileriosis, and hepatozoonosis. In this study, we investigated the presence and diversity of tick-borne Apicomplexa in wildlife and ticks inhabiting the Amazon rainforests of French Guiana. To this end, we conducted molecular screening and typing using 18S rRNA sequences on a collection of 1161 specimens belonging to 71 species, including 44 species of wild mammals, five species of passerines, and 22 species of ticks. We characterized eight genovariants of Babesia, Theileria, Hemolivia, and Hepatozoon parasites, some matching known species, while others suggested potential novel species. These parasites were detected in wild mammals, including opossums, sloths, armadillos, porcupines, margays, greater grisons, and ticks, but not in passerines. Finally, similarities with surveys conducted in Brazil highlight the specific sylvatic transmission cycles of South American tick-borne Apicomplexa.

法属圭亚那野生动物和蜱虫中的蜱传Apicomplexa。

蜱传吸虫包括一组寄生虫，可引起严重的医疗和兽医疾病，包括巴贝西亚原虫病、蜱虫病和肝吸虫病。在这项研究中，我们调查了栖息在法属圭亚那亚马逊热带雨林中的野生动物和蜱虫中蜱传吸虫的存在和多样性。为此，我们使用 18S rRNA 序列对隶属于 71 个物种的 1161 份标本进行了分子筛选和分型，其中包括 44 种野生哺乳动物、5 种雀形目动物和 22 种蜱虫。我们鉴定了巴贝西亚原虫、毛丝虫、血丝虫和肝吸虫寄生虫的 8 个基因变异体，其中一些与已知物种相匹配，另一些则可能是新物种。这些寄生虫在负鼠、树懒、犰狳、豪猪、箭猪、大灰狼和蜱等野生哺乳动物体内均有检出，但在雀形目动物体内没有检出。最后，与在巴西进行的调查相似，凸显了南美蜱传吸虫的特殊传播周期。

期刊介绍： Parasite is an international open-access, peer-reviewed, online journal publishing high quality papers on all aspects of human and animal parasitology. Reviews, articles and short notes may be submitted. Fields include, but are not limited to: general, medical and veterinary parasitology; morphology, including ultrastructure; parasite systematics, including entomology, acarology, helminthology and protistology, and molecular analyses; molecular biology and biochemistry; immunology of parasitic diseases; host-parasite relationships; ecology and life history of parasites; epidemiology; therapeutics; new diagnostic tools. All papers in Parasite are published in English. Manuscripts should have a broad interest and must not have been published or submitted elsewhere. No limit is imposed on the length of manuscripts, but they should be concisely written. Papers of limited interest such as case reports, epidemiological studies in punctual areas, isolated new geographical records, and systematic descriptions of single species will generally not be accepted, but might be considered if the authors succeed in demonstrating their interest.
