Abstract
Experimental infection method for Edwardsiellosis was studied to imitate histopathologically natural infections in the Tilapia Oreochrimis niloticus. Prior to the bacterial challenge, the intestine of tilapia was damaged by 0.2ml of 30% hydrogen peroxide introduced through a silicon tube which was inserted 4 to 5cm into the intestine from anus. E. tarda was mixed a 10% Gum arabia and administered into the stomach by a cannula 20 hours after the hydrogen peroxide treatment. Bacterial doses used were from
틸라피아에 실험적으로 Edwardsiella tarda를 경구감염 시켰다. 틸라피아의 장을 자극시키지 않았을 때는 E. tarda가 감염되지 않았으나 과산화수소로 장을 자극시킨후 E. tarda를 투여하였더니 감염되었다. 150~200g되는 틸라피아 한마리에
