- Abstract
[Objective]The present experiment was conducted to understand Pallisentis (Neosentis) celatus parasitic mechanism in Monopterus allbus in order to provide scientific information for prevention and treatment of P. celatus. [Method]Morphological characteristics of P. celatus and histopathology of intestinal tract of M. allbus infected by P. celatus were observed with scanning electron microscopy and paraffin histological section. [Result] The Results showed that rostrum of P. celatus was smaller, and hook rooted in rostrum was horned, sharp and smooth. Mucros pointed to the back of worm. The body wall of P. celatus was composed of cuticle, epidermis and muscle layer, and digestive tract did not existed in the worm. Because P. celatus and M. allbus squeezed each other, it brought about mechanical damage of M. allbus intestine and disappearance of cuticle, epidermis and muscle layer in parasitic position. Meanwhile the contact segment of P. celatus with intestinal mucosal was in deformation seriously, which resulted in hardly distinguishing between worm suface and intestinal mucosal. [Conclusion] On the early stage of P. celatus parasiting in intestinal tract of M. allbus, hook of rostrum plays an important fixing role. As the growth of P. celatus, intestinal mucosa of M. allbus and body wall of P. celatus integrate each other, and P. celatus retracts rostrum into body wall of itself.
