A study of infestation of Alburnoides bipunctatus with Ligula intestinalis in Latian reservoir Dam Lake, Tehran province, Iran: A histopathological stud

. Objective: The objective of this study was to report infestation of the fish with Ligula intestinalis as a food borne zoonoses and to study its histopathological effects on one Alburnoides bipunctatus in Latian reservoir Dam Lake, Tehran province, Iran. Material and methods: In July 2010, 6 fish (Alburnoides bipunctatus) from Latian reservoir Dam Lake, Tehran province, Iran were referred to Laboratory. After autopsy, two of them (Mature and Female) were found infested with plerocercoid of Ligula intestinalis based on taxonomical features. For histopathological studies samples were stained with Haematoxylin and Eosin (H&E) and observed under light microscopy. Results: Pathological findings showed inflammation of the reservoir adipose tissue (in the loose conjunctive tissue between lipocytes) surrounding intestine. Severe atrophy in follicular cells of ovary was evident. In liver cholangiohepastitis with metaplastic hyperplasia was seen. Conclusion: Considering the importance ofLigula intestinalis as a food borne parasite, performance of other comprehensive studies is a necessity.
