Abstract: Kidney of Clarias batrachus infected with Procamallanus showed varying degrees of histopathological alterations on 15, 30, 45 and 60 days post-infection. The infected kidney showed variable sized glomeruli, cloudy swelling in tubules, vacuolar/atrophic degeneration, fibrosis, mild degenerative changes in distal convoluted tubules, enlarged Bowmen?s capsule, necrotic changes as well as increased granulation and hyperplasia in proximal convoluted tubules after 15 days. After 30 days of infection, the changes were rupture of Bowmen?s capsule wall, degenerative changes, edema, necrosis, pyknosis, karyorrhexis and karyolysis in proximal and distal convoluted tubules, fibrosis, cloudy swelling and inflammatory lymphocytes, proliferation and shrinkage in glomeruli, and vacuolization in proximal convoluted tubules as well as cloudy swelling. After 45 days, the infected kidney showed cloudy swelling in glomeruli as well as variation in their size, infiltration of RBCs in intralobular vein and necrosis in proximal convoluted tubules, cloudy swelling in interstitium, vacuolization in the epithelial lining cells, necrosis in haemopoietic tissue and inflammatory edema. After 60 days post-infection, the changes were rupture of intralobular vein, cloudy swelling, necrosis in few proximal convoluted tubules, atrophy and shrinkage in glomeruli, distinct inflammatory edema, pyknosis, karyorrhexis and karyolysis, aggregation of lymphocytes and dilation in blood vessels.
