Fish of Oreochromis niloticus were acted with various concentrations of Enterotoxigenic Escherichia coli (ETEC) as (103-105, 106-107 109-1010/ml water). The study was carried out to discover the impact of E. coli toxins on Oreochromis niloticus fish during the whole of physiological liver function and histopathological changes in the liver. The principles of GPT, GOT and alkaline Phosphatase categorized between (905.90 IU/L -75.40 IU/L), (4827.7 IU/L - 385.50 IU/L) and (106- 107 CFU /ml - 103 - 105 CFU / ml) for the three liver enzymes individually. When Oreochromis niloticus liver was exposed to Escherichia coli, it displayed signs of fatty degeneration, ballooning deterioration, pyknotic hepatocyte nuclei, necrosis of the hepatocytes and pancreatic acini, haemorrhage, angering WBC infiltration, and hemosiderin shade buildup. The experiment's verdicts showed that the liver of O. niloticus was intensely vulnerable to E. coli contamination, which caused bigger liver enzyme levels, erratic and irreversible liver damage, and eventually the highest aggregation of mortality.
