摘要
目的:本研究分析了来自巴西东北海岸 4 个不同物种的 143 种琵琶鱼寄生虫。本研究的目的是重新详细描述从巴西琵琶鱼身上收集到的 R. (I.) vicentei,包括首次使用扫描电子显微镜(SEM)观察该物种:方法:对在新月形甘油系列中发现的澄清线虫进行拍照和测量(单位:毫米),并对一些标本进行扫描电镜观察。使用带绘图管的光学显微镜进行说明:发现的线虫被确认为 Raphidascaris (Ichthyascaris) vicentei,感染了 6.29%的鱼类。详细的形态分析表明,在该物种中首次发现了以下特征:唇乳头、狭窄的侧唇和雄性棘突的详细结构。这些贡献有助于填补文献空白,扩大对该寄生虫形态的了解:结论:在四种恙螨中发现 R. (I.) vicentei 可能表明寄主特异性较低,突出了其对不同寄主的适应性。此外,还提供了新的寄主记录。这项研究提供了迄今为止对 R. (I.) vicentei 最全面的形态学描述,为更好地了解巴西东北海岸寄生虫的生物多样性提供了重要见解,并为今后研究这些寄生虫在该地区鱼类种群中的生态和影响奠定了基础。
Redescription of Raphidascaris (Ichthyascaris) vicentei (Nematoda: Raphidascarididae) Parasitizing Lutjanid Fishes (Actinopterygii: Lutjanidae) from the Northeast Coast of Brazil, Including First Observation Using SEM
Purpose
In this study, 143 lutjanid fishes representing four different species from the Northeast coast off Brazil were analyzed for parasites. The aim of the present study is to provide a detailed redescription of R. (I.) vicentei, collected from lutjanid fishes in Brazil, including the first observation of the species using scanning electron microscopy (SEM).
Methods
Nematodes found clarified in a crescent glycerin series, were photographed and measured (in mm), and some specimens destined for SEM. The Illustrations were made using an optical microscope with a drawing tube.
Results
Nematodes found were identified as Raphidascaris (Ichthyascaris) vicentei, infecting 6.29% of the examined fish. Detailed morphological analysis revealed the following characteristics observed for the first time in this species: labial papillae, narrow lateral alae and the detailed structure of male spicules. These contributions help filling the gaps in the literature and expand the knowledge of this parasite morphology.
Conclusions
The presence of R. (I.) vicentei in four lutjanid species may indicates low host specificity, highlighting its adaptability to different hosts. Furthermore, new host records are given. This research provides the most comprehensive morphological description of R. (I.) vicentei to date, generating crucial insights for a better understanding of the parasitic biodiversity off the Brazilian Northeastern coast of Brazil, as well as establishing foundation for future investigations on the ecology and impacts of these parasites in fish populations from this region.
期刊介绍:
Acta Parasitologica is an international journal covering the latest advances in the subject.
Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews.
The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
