摘要

Lamproglena von Nordmann, 1832种的雌性寄生在硬骨鱼的鳃上,38种名义种主要基于形态学资料。这些物种中只有四个已经被遗传表征,并且没有线粒体数据可用于该属。本研究旨在提供另外两个非洲Lamproglena的代表性核糖体DNA (rDNA)数据:1956年的Lamproglena clariae Fryer和2001年的Lamproglena hoi Dippenaar, Luus-Powell et Roux,以及这两个物种和另外两个非洲物种Lamproglena hemprichii von Nordmann, 1832年和1944年的Lamproglena monodi Capart的线粒体DNA (mtDNA)。4种分别采自蛱蝶科、蛱蝶科、蛱蝶科和蛱蝶科。分别获得了L. clariae和L. hoi具有代表性的18S rDNA和28S rDNA数据,并获得了cox1 mtDNA。各自的单倍型支持所有物种使用所有三个基因区域的独特性。有趣的是,物种似乎更多地按地理来源而不是寄主家庭分组,L. hoi与其他非洲物种的关系比与从鲤科寄主收集的亚洲物种的关系更密切。尽管本文的研究结果大大增加了Lamproglena的分子数据,但仍有32种(>80%)没有遗传数据。因此,本文对结果的解释是初步的,在对该属和该科其他成员(如1758年的林奈勒纳)的系统发育进行适当研究之前,还需要更多的数据。

Genetic characterisation of four Lamproglena spp. (Copepoda, Lernaeidae) from Africa and the first mitochondrial data.

Females of species of Lamproglena von Nordmann, 1832 are parasitic on the gills of teleost fishes and the 38 nominal species are based on mainly morphological data. Only four of these species have been genetically characterised and no mitochondrial data are available for the genus. The present study aimed to provide representative ribosomal DNA (rDNA) data for two additional species of Lamproglena from Africa: Lamproglena clariae Fryer, 1956 and Lamproglena hoi Dippenaar, Luus-Powell et Roux, 2001, alongside mitochondrial DNA (mtDNA) for these and two other African species, Lamproglena hemprichii von Nordmann, 1832 and Lamproglena monodi Capart, 1944. The four species were collected from Clariidae, Cyprinidae, Alestidae and Cichlidae, respectively. Representative 18S rDNA and 28S rDNA data were obtained for L. clariae and L. hoi, while cox1 mtDNA was obtained for all four species. The respective haplotypes supported the distinctness of all species using all three gene regions investigated. Interestingly, species appeared to be grouped more by geographical origin than host family, with L. hoi more closely related to other African species than to Asian species also collected from cyprinid hosts. Even though the results presented here greatly add to the molecular data available for Lamproglena, there are still 32 (>80%) species for which no genetic data are available. The interpretation of the results presented here is thus preliminary and much more data are required before the phylogeny of this genus, and other members of the family, such as Lernaea Linnaeus, 1758, can be studied appropriately.

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.
