Virulence of Aeromonas hydrophila in frog (Rana tigerina) were studied. A number of 60 frogs (2-3 month-olds) were induced by intraperitoneal injection route with A. hydrophila at concentration of 5*10**(6), 5*10**(7) cfu/frog and dipping route at concentration of 5*10**(6), 5*10**(7) cfu/ml. The result showed that accumulative mortality was 33.3 percent and 75 percent respectively after 12 days in only intraperitoneal administration group. The affected frog showed depress, anorexia, decreased movement, dull colour skin and pectechial hemorrhage of proximal of both hind limbs and necrosis of hepatocytes. The hematology and histopathology were also studied.
