ABSTRACT
Present study was conducted to investigate histopathology of intestinal tissue of freshwater fish, Mastacembelus
armatus, parasitized by Pseudophyllidean cestodes, Polyonchobothrium Sp. and Senga Sp. Obviously, the direct effect
of cestode parasites mainly depend on their holdfast organs. In all 360 host specimens of Mastacembelus armatus
were examined out of which 212 were found infected by cestode parasites viz. Polyonchobothrium Sp. and Senga Sp.
Total incidence of cestodal infection was recorded to be 58.88 % during February, 2015-January, 2016. Deep penetration
of intestinal tissue of Mastacembelus armatus infected with Polyonchobothrium Sp. and Senga Sp. were found to
occur due to penetrative scolex. Transverse section of intestinal tissue showed that cestodes attached to mucosal,
sub-mucosal and muscularis mucosa of intestine with scolex and damaged host intestinal villi, invaded deep forming
cyst. Its scolex caused destruction and defection of the infected intestinal tissue of fish host. Parasite derives nutritive
material, required for growth, from host tissue by causing damage to it. Thus the study reveals that association of
Polyonchobothrium Sp. and Senga Sp. with Mastacembelus armatus is more negative on health of fish host.
