Abstract

Although some studies have identified parasites in green turtles (Chelonia mydas), little is known about the morphology of helminth eggs in the feces of these animals. The aim of this study was to morphologically characterize helminth eggs recovered in coproparasitological exams by sedimentation and to analyze their relationship with helminth species recovered during necropsy of juvenile specimens of C. mydas. Four different egg morphotypes were found, identified, and classified as digenetic trematodes of the families Microscaphidiidae, Cladorchiidae, and Spirorchiidae. There was morphological diversity in the size of the eggs measured directly in adult parasites, with sizes ranging from 19.07 to 99.28 μm in length and from 11.35 to 45.66 μm in width. The observation of eggs on coproparasitological exams is important for studying the ecology of sea turtle parasites, since the life cycle of some species is not yet fully understood.

巴西圣州Espírito海岸绿龟(Chelonia mydas)吸虫卵的形态特征

尽管一些研究已经在绿海龟（Chelonia mydas）身上发现了寄生虫，但对这些动物粪便中蠕虫卵的形态知之甚少。本研究的目的是从形态学上表征通过沉淀在共寄生虫学检查中回收的蠕虫卵，并分析它们与在对C.mydas幼年标本进行尸检时回收的蠕虫物种的关系。发现、鉴定了四种不同的卵形态类型，并将其归类为微囊吸虫科、枝睾吸虫科和螺科的双生吸虫。在成年寄生虫中直接测量的卵的大小存在形态多样性，大小从19.07到99.28μm不等，从11.35到45.66μm不等。由于某些物种的生命周期尚未完全了解，因此在共寄生虫学检查中观察海龟卵对于研究海龟寄生虫的生态学非常重要。

期刊介绍： A bilingual open-access publication, Ciencias Marinas (CM) is an international peer-reviewed journal that contains original research findings in all areas of marine science. It is published quarterly by the Autonomous University of Baja California, Mexico, and all its contents are publicly available on our journal website. Though a limited number of copies are still printed, the journal is mainly distributed in its electronic format. CM was conceived in 1973 as part of an academic project aimed to entice local researchers to publicly disclose their findings by adopting the culture of peer-review publishing. This academic project evolved into an international journal after accepting papers from researchers in the United States and, eventually, other parts of the world. Because of the diversity in authorship, CM issues were initially published in either Spanish or English, and occasionally in both languages. It was not until 1984 when CM included both language versions of all its contents, and it then became the fully bilingual journal it still is today. At CM we believe our inclusive format allows us not only to address a wider range of submissions from international authors but also to make published findings available to a wider international audience. So whether you are looking for information on the redfish in Icelandic waters or the physical and biological properties of the Gulf of California, feel free to peruse CM contents. You may find them to provide source material for your research.
