title: SEM studies on Trichurus muris from Psammomys obessus from Sinai Peninsula, Egypt.
abstract: The whipworm Trichuris muris was recovered from the caecum of the wild rodent Psammomys obessus trapped from Sinai Peninsula, Egypt. The cuticular surface ultrastructure is described using SEM. T. muris is closely related to other Trichuris species but can be distinguished from them mainly by differences in the posterior end of males. Details of the surface such as the bacillary gland, cuticular inflations and several morphological details obtained by scanning electron microscopy confirmed the characteristics that differentiate the species. P. obessus (Cretzschmar, 1828) is considered a new host record and Sinai is considered a new locality for the genus. This may through light on the spread of T. muris between Asia and Africa.
