HISTO-PATHOLOGICAL EFFECT OF SENGA SPECIES (CESTODE: PSEUDOPHYLLIDEA) IN INTESTINE OF PISCIAN HOSTS
*Pinky Kaur
ABSTRACT Present study was conducted to investigate the occurrence and pathological changes induced by Senga sp. in the intestine of freshwater fishes, Channa punctatus and C. striatus. In all, 175 and 150 specimens of Channa punctatus, C. striatus, were examined, out of which 60 and 42 were found infected by cestode parasite, respectively. The total percentage of cestodal infection was calculated to be 34.28 % in Channa punctatus, 28.0 % in C. striatus. Parasites were found attached to the submucosal layer of intestine with scolex and diagnostically characterized by excess mucus secretion which resulted in severe degeneration and necrosis in mucosal, submucosal, serosa layer and muscular layers Histo-pathological examination of infected intestine of C. punctatus revealed ruptured serosa layer, vacuolization in tunica muscularis and lamina propria, shortened, fused and irregular shaped villous processes.
