Results & Conclusion: Isolation of rods gram negative bacteria determined as Aeromonas sobria by using the tests previously described by other investigators. Microscopic examination of the tissues revealed histopathologic changes including hemorrhages, necrosis and degeneration of muscular cells and hemorrhages, appearance hyaline, rupture in kidney and shrinkage of tubules and necrosis of interstitial tissue and distention Bowmans space in kidney .in liver degeneration of hepatocytes, congestion of blood vessels were seen, congestion, necrosis and degeneration of sub-mucusal in the intestine tissue. The clinical, histopathological and bacterial examination results indicated that Aeromonas sobria similar to other motile Aeromonases caused histopathological signs in Ctenopharyngodon idella.
