Euclinostomum heterostomum and E. ardeolae in tilapia species of Aswan Governorate, Egypt: morphological, molecular, and histopathological characterization

Exploring the Relationship Between Water Quality, Parasitic Infestation, and Pathological Alterations in Tilapia Fish

“…Moreover, similar changes were detected in the renal tissue and the EMC causing tubular nephritis accompanied with chronic inflammatory signs with fibrous tissue formation surrounding the cyst. All detected histopathological changes coincide with previous studies that demonstrated the damage caused by parasitic invasion of the viscera, including the gills, liver, musculature and kidney (Younis et al, 2020;Younis et al, 2022;Shinn et al, 2023).…”

Morphological and molecular identification of Euclinostomum heterostomum in the spotted snakehead (Channa punctata) in Narayanganj, Bangladesh

“…The present study represents the rst molecular report of E. heterostomum in the country. This nding is consistent with previous research using molecular approaches for identifying E. heterostomum in Channa striata(Kaur et al, 2020)d heterostomum and E. ardeolae in Tilapia(Younis et al, 2022). The distinctive morphological variances were validated through a comprehensive analysis that compared the sequences of internal transcribed spacers (ITS) within ribosomal DNA and the mitochondrial gene cytochrome c oxidase I (CO1) across 39 individual specimens(Caffara et al, 2011).…”

Prevalence of diegenetic encysted metacercariae and their histopathological alterations in the Nile tilapia (Oreochromis niloticus), and the African catfish (Clarias gariepinus)

“…In Egypt, parasitic diseases represent a large sector of fish diseases about 80% (GAFRD, 2020; Eldanasory et al, 2022). Therefore, many previous studies have been conducted to explore the different parasites infecting various fish species (Eman et al, 2014;Ghoneim et al, 2015;Shaheen et al, 2017;Mahmoud et al, 2018;Younis et al, 2022;Abd-ELrahman et al, 2023). Endoparasites, particularly metacercaria of digenetic trematodes can affect the wild and cultured freshwater fish's health causing not only high economic losses but also can seriously affect human health, leading to sever digestive disorders (WHO, 2017).…”
