摘要

南非沙漠是温带潮间带地区的一个主要组成部分,已知它也参与了几组寄生虫的生命周期和传播。然而,对这些鱼类吸虫多样性的认识尚不完整。本研究在南非沿海的6个地点采集了两种Cuvier鱼,即超级klipfish Clinus superciliosus (Linnaeus)和钝鼻klipfish Clinus cottoides Valenciennes,并检查了吸虫的存在。suarikov, 1959在超纤毛瓢虫的玻璃体和大脑以及棉绒瓢虫的玻璃体中发现了包囊蚴。结合形态学和分子序列数据(28S rDNA、ITS2 rDNA区域和COI mtDNA)进行详细分析,发现它们属于两个种,一个是Cardiocephaloides physalis (Lutz, 1926),另一个是Cardiocephaloides的未知种。本研究首次报道了作为吸虫中间寄主的临床鱼类,揭示了南非Cardiocephaloides的多样性高于以往的记录,并强调了进一步研究这些吸虫物种的生命周期的必要性。本研究基于分子序列数据,证实了该植物广泛的地理分布。临床鱼类与头足纲囊蚴之间的宿主-寄生虫相互作用尚待探讨。

Molecular and morphological characterisation of the metacercariae of two species of Cardiocephaloides (Digenea: Strigeidae) infecting endemic South African klipfish (Perciformes: Clinidae).

South African clinids are a major component of the temperate intertidal regions that are also known to participate in life cycles and transmission of several groups of parasites. However, the knowledge of trematode diversity of these fishes is incomplete. In this study, two species of Clinus Cuvier, the super klipfish Clinus superciliosus (Linnaeus) and the bluntnose klipfish Clinus cottoides Valenciennes, were collected from six localities along the South African coast and examined for the presence of trematodes. Metacercariae of Cardiocephaloides Sudarikov, 1959 were found in the eye vitreous humour and brain of C. superciliosus and in the eye vitreous humour of C. cottoides. Detailed analyses integrating morphological and molecular sequence data (28S rDNA, ITS2 rDNA-region, and COI mtDNA) revealed that these belong to two species, Cardiocephaloides physalis (Lutz, 1926) and an unknown species of Cardiocephaloides. This study provides the first report of clinid fishes serving as intermediate hosts for trematodes, reveals that the diversity of Cardiocephaloides in South Africa is higher than previously recorded, and highlights the need for further research to elucidate the life cycles of these trematode species. The broad geographical distribution of Cardiocephaloides spp. was confirmed in the present study based on molecular sequence data. The host-parasite interactions between clinid fishes and metacercariae of Cardiocephaloides are yet to be explored.

期刊介绍: FOLIA PARASITOLOGICA, issued in online versions, is an international journal that covers the whole field of general, systematic, ecological and experimental parasitology. It publishes original research papers, research notes and review articles. Contributions from all branches of animal parasitology, such as morphology, taxonomy, biology, biochemistry, physiology, immunology, molecular biology and evolution of parasites, and host-parasite relationships, are eligible. Novelty and importance in the international (not local or regional) context are required. New geographical records of parasites, records of new hosts, regional parasite and/or host surveys (if they constitute the principal substance of manuscript), local/regional prevalence surveys of diseases, local/regional studies on epidemiology of well known diseases and of parasite impact on human/animal health, case reports, routine clinical studies and testing of established diagnostic or treatment procedures, will not be considered. One species description will also not be considered unless they include more general information, such as new diagnostic characters, host-parasite associations, phylogenetic implications, etc. Manuscripts found suitable on submission will be reviewed by at least two reviewers.
