Clinostomid metacercariae infect a wide range of freshwater fish species, posing a zoonotic risk to human health when consumed raw or undercooked, potentially leading to Halzoun disease. Although these parasites are generally considered a health threat in Asian countries, they are also present in various regions of Türkiye and have been found in 12 different freshwater fish species commonly consumed in local cultures. However, their presence has not been reported in the endemic Anatolian fish, Alburnus escherichii. This study aims to determine the presence of clinostomid species in A. escherichii from the Sarısu stream in Eskişehir, Türkiye.
In addition to using a combination of ecological, morphological, molecular and histopathological approaches, our findings revealed the presence of Clinostomum complanatum within the branchial and buccal cavities of A. escherichii. Further histopathological examination revealed encysted metacercariae of C. complanatum invading the host tissues encapsulated within a thin fibrotic layer and accompanied by moderate inflammatory cell infiltration and degenerative changes in muscle cells.
These results provide new insights into the geographical and host distribution as well as histopathological impacts of C. complanatum metacercariae in teleost species.
斜睾科吸虫囊蚴感染多种淡水鱼类，当这些鱼类被生食或未煮熟时，会对人类健康构成人畜共患病风险，可能导致哈尔宗病。尽管这些寄生虫在亚洲国家通常被视为健康威胁，但它们在土耳其的各个地区也有存在，并且在当地文化中常见的12种不同淡水鱼类中被发现。然而，在当地特有的安纳托利亚鱼类埃氏雅罗鱼中尚未有它们存在的报道。本研究旨在确定土耳其埃斯基谢希尔萨勒苏河中的埃氏雅罗鱼体内是否存在斜睾科吸虫物种。
除了采用生态、形态、分子和组织病理学方法相结合外，我们的研究结果显示埃氏雅罗鱼的鳃腔和口腔内存在扁体斜睾吸虫。进一步的组织病理学检查发现，扁体斜睾吸虫的囊蚴包囊侵入宿主组织，包囊被一层薄的纤维化层包裹，伴有中度炎性细胞浸润和肌肉细胞的退行性变化。
这些结果为扁体斜睾吸虫囊蚴在硬骨鱼物种中的地理分布、宿主分布以及组织病理学影响提供了新的见解。
