Abstract

Summary During a survey of soil nematodes in South Africa, a species of predatory nematodes, namely Mylonchulus hawaiiensis was recovered from soil in the Magoebaskloof mountain of Limpopo Province, South Africa. The morphology of the material studied fit well with the previous populations of the same species. A molecular study of 18S rDNA region of M. hawaiiensis indicated a 100% similarity between the South African population and the Japanese population of M. hawaiiensis (AB361438; AB361439; AB361440; AB361442). In addition, phylogenetic analysis placed all M. hawaiiensis in a group with 0.97 posterior probability. Additionally, ITS rDNA of M. hawaiiensis amplified for the first time. However, Principal component analysis (PCA) showed a morphological variation among the different populations of M. hawaiiensis. In addition, haplotype analysis also revealed that the South African population is close to the Japanese population. In conclusion, 18S rDNA was a good marker for detecting M. hawaiiensis. Measurement, photographs, and phylogenetic position of South African M. hawaiinesis are given.

首次从分子角度观察南非的 Mylonchulus hawaiiensis

摘要在对南非土壤线虫进行调查期间，从南非林波波省 Magoebaskloof 山的土壤中发现了一种掠食性线虫，即 Mylonchulus hawaiiensis。研究材料的形态与该物种以前的种群十分吻合。哈瓦伊蝇 18S rDNA 区域的分子研究表明，南非种群与日本哈瓦伊蝇种群（AB361438；AB361439；AB361440；AB361442）的相似度为 100%。此外，系统进化分析还将所有哈瓦伊蝠鲼归入一个组，后验概率为 0.97。此外，还首次扩增了哈瓦伊蝠的 ITS rDNA。然而，主成分分析（PCA）显示，M. hawaiiensis 不同种群之间存在形态差异。此外，单倍型分析还显示南非种群与日本种群接近。总之，18S rDNA 是检测 M. hawaiiensis 的良好标记。本文给出了南非哈瓦伊蝠的测量值、照片和系统发育位置。

期刊介绍： Helminthologia (HELMIN), published continuously since 1959, is the only journal in Europe that encompasses the individual and collaborative efforts of scientists working on a different topics of human, veterinary and plant helminthology. The journal responsibility is to enrich the theoretical and practical knowledge in very specific areas and thus contribute to the advancements in human and veterinary medicine and agronomy. Taking the advantage of comprehensive and multidisciplinary approaches journal still maintains its original spirit and is principal source of fresh scientific information regarding helminths, endoparasites and plant parasites. Addressing the most up-to date topics journal gained rightful and exceptional place next to the other high-quality scientific journals publishing in its field.
