Humans benefit from the fish since it is a good source of protein. Enterotoxigenic Escherichia coli (ETEC) doses of 103-105, 106-107, and 109-1010 CFU/ml water were used to treat Oreochromis niloticus [1]. The study was carried out to see how E. coli toxins affected Oreochromis niloticus fish in terms of cell blood counts (WBCs, RBCs, and Platelets), haemoglobin concentration, and muscle histological alterations. The haematological indices of WBCs, RBCs, Platelets, and haemoglobin ranged from (90.70 K/ml -7.10 K/ml), (2.00 m/ml – 0.53 m/ml), (21 K/ml – 3 K/ml), and (8.2 G/dl to 2.50 G/dl). The number of white blood cells (WBCs), red blood cells (RBCs), and platelets (RBCs) in the In all phases of the trial, platelets and haemoglobin were lower than the control. Degeneration, necrosis, atrophy, and inflammatory infiltration of WBCs were seen in O. niloticus treated with E. coli. The findings demonstrated that high levels of E. coli toxins in the muscles of O. niloticus caused muscular tissue damage, which might be passed on to humans and cause significant sickness. It is recommended that you avoid fishing in sewage-polluted oceans or rivers, as well as using sanitation on farms.
