Pathological effect on naturally infected kidneys of freshwater murrels by Euclinostomum heterostomum metacercariae

Abstract

Present investigation was carried out to study the histo-pathological alterations induced by metacercariae of digenetic trematode, Euclinostomum heretostomum on the kidney of Channa striatus and Channa marulius in natural condition. Histo-architectural alterations induced by parasite included reduced size of glomeruli, severe degeneration and necrosis of haemopoietic tissue and tubule cells with hypertrophied nuclei in C. striatus. Whereas, infected kidney of C. marulius exhibited the development of several melano-macrophage centers, hypertrophied nuclei of tubule cells and detached epithelial cells of renal tubules. Therefore an attempt has been made to record the first naturally occurring pathogenicity of E. heterostomum in kidney of freshwater murrels.

Aumento de mastócitos, neutrófilos e células mucosas e menos frequentemente de eosinófilos e linfócitos ao redor do corpo do parasito no lúmen intestinal.…”

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

“…involved a decrease in glomerular size, severe degeneration, and necrosis of hemopoietic tissue. In C. marulius, the infected kidney displays melanomacrophage centers, hypertrophied nuclei of tubule cells, and detached epithelial cells (Kaur et al, 2016). Heavy in ltration of immune cells at cyst attachment sites was observed, leading to tissue damage (P. A.…”
