The hydropic degeneration of hepatocytes are characterized by cytoplasmic vacuolations and areas of hepatocytic necrosis with cellular infiltration. There may be dilatation of sinuses and disruption of hepatic cords seen in affected animals [20, 22, 27]. Lesions in Kidneys reveal as vascular congestion and focal areas of haemorrhages. Haemorrhages used to be intertubular (**Figure 12**). Cortical tubular epithelium may invariably swollen or degenerated with increased cytoplasmic granularity. The degenerative and necrotic changes of tubular epithelium will be diffuse in nature. Generalized degenerative and necrotic changes in the tubular epithelial cells

There will be depletion of lymphocytes from germinal centre of the spleen and widespread necrosis can also be seen Spleen reveals as variably dilated and engorged vasculature, haemosiderosis, necrosis of lymphoid elements and infiltration of inflammatory cells mainly neutrophils [29, 30]. The microscopic lesions in the intestine are characterized by haemorrhages, necrosis of villi epithelium and desquamation of lining epithelium with focal infiltration of mononuclear cells in

Swine Pasteurellosis is an acute infection in swine caused by members of the *Pasteurella multocida*. Swine throughout the world are affected by pasteurellosis. *Pasteurella multocida* of swine can be isolated from natural field cases. Field isolate of *Pasteurella multocida* on sheep blood agar yield non-hemolytic, round, grayish, smooth or mucoid colonies. The isolates are Gram negative, cocco-bacilli in morphology and non-motile facultative anaerobe. Biochemically the isolates are positive for oxidase, catalase, indole production, reduction of nitrate, glucose and sorbitol

may also be seen with variable severity from mild to high [20, 28].
