The gross pathological examination showed hemorrhagic, degenerative or necrotic and proliferative nature in liver and kidneys. Microscopic examination of liver showed fatty changes, perilobular necrosis megalocytosis and megalokaratosis in centrilobular zone. Kidneys showed necrosis of proximal convoluted tubules with cellular casts in distal convoluted tubules. There was increase in relative weights of bursa, spleen and thymus. Hematological studies showed significant reduction in hemoglobin, packed cell volume and total erythrocyte counts. Serum biochemical analysis revealed a significant decrease in serum total protein and cholesterol values contrary to increase in serum glucose level and significantly higher serum SGOT and SGPT levels in affected birds.
