Birds live in open environment carry a great risk of parasitic infections. The most im-portant of these parasites are pathogenic cestodes. In February 2016, a total of 10 laughing dove (Streptopelia senegalensis) were examined grossly and microscopically. This study estimated ultrastructural features and histopathological impacts of 27 cestodes parasites isolated from the intestine of laughing dove (S. senegalensis) collected from Damietta Governorate. Data on morphology, hosts and infection intensity of the para-sites were provided. The intestine was opened longitudinally examined looking for hel-minthes which examined by using both light and electron microscopy for identification.
Fine morphological criteria of cestodes in the present study are shown by using both light and electron microscopy. Microtriches, the surface features among cestodes comprised two basic types that actually play in the lives of cestodes and an integral role in the for-mation of certain "hard" structure in cestodes. At present some surface features "microtrich-es" are illustrated through scanning electron microscopy. Tissue samples were also taken for histopathological examination.
