Fascioliasis is not only an endemic infectious disease recorded in the most tropical and sub-tropical areas, but it also has been recognized as a significant disease attributed to appreciable animal mortalities, growth retardation, drops in livestock production, and condemnation of the infected livers attributed to hepatic damage. The cross-sectional study was conducted on slaughtered cattles among 2018 to 2022 in abattoirs belonging to Qena province, Egypt. Each selected carcass was inspected well macroscopically for adult liver flukes by dissecting the livers and lymph nodes.
For histopathological study, specimens from the two aforementioned tissues were taken and fixed in 10% neutral buffered formalin. Postmortem observation represented whitish pale and firm livers which indicated necrosis; notably bile ducts engorged with liver fluke and a thickened opaque wall. Concerning lymph nodes, darkish red collections obviously distributed because of suffered intense congestion and hemorrhages. For histopathological changes, infected cattle denoted hepatic cytoplasmic vacuolation of hepatocytes and necrobiotic changes of the liver. Thickening and hyperplasia of the bile duct wall was elucidated. Besides that, there was hemorrhagic inflammation of the lymph nodes and remarkable lymphoid depletion of the white pulp.
We explored some evidence of a close relation between fasciola infection and damage in else critical organs other than liver fundamentally lymph nodes.
