| Abstract | ||
| The present study was conducted in the fish diseases laboratory of College of Veterinary Medicine-University of Baghdad to investigate the effect of magnetized treated water on common carp Cyprinus carpio infected with Aeromonas hydrophila.A total of 80 specimens of common carp were used ranges between 150 gm in weight. Fish were distributed randomly with ten fish to every aquarium with diamension 70x40x40 cm upon four treatment. First treatment considered control which free of magnetized water while the second treatment contained magnetized treated water with 500 gauss, third treatment contained magnetic treated water with1000 gauss, forth treatment contained magnetized treated water with1500 gauss with two replicates for each treatment through the period of experiment attain four weeks. The experiment represented by inducing the infection by addition of bacterial suspension of Aeromonas hydrophila to the water of the aquarium with dose of 107 cfu/10 liter of aquarium water. The histopathological results reports the best treatment 1500 gauss which mainly the treated treatments were less sever compared to the control , the best result in which presences of epithelial lamellar hyperplasia of gills and biliary epithelial layer with lymphoid aggregation in the hepatic and renal tissue mainly in fourth treatment as well as presence of basal cortical tubules specially in the kidney of the second treatment while severe sloughing and separation of primary and secondary epithelial lamellae association with focal necrosis in liver and kidney with evidence of observation of colonies mainly in the hemorrhagic areas of gill and renal tissues. Results concluded the efficiency of magnetized treated water in the treatment and improvement of health status of trial fish which increased with magnetized intensity increasing with of time. | ||
