Abstract

Enterobius vermicularis is nematode the commonest human parasites particularly among
children aged school based on behavioral and ecological factors that facilitate spreading. To ensure
the phylogenetic relation to Nematoda ultrastructure of Enterobius vermicularis worms
and male spermatogenesis criteria must be studied
This study was performed on school children from both rural and urban areas to identify the
Enterobius vermicularis worm in fecal samples. The adults were examined macroscopically
and microscopically as well as by scanning electron microscopy (SEM), for strain identification
and spermatogenic criteria were examined by transmission electron microscopy (TEM).
The SEM showed the criteria of different parts of the adult female and TEM clarified the
males' spermatogenic criteria that showed many ribosomes, rough endoplasmic reticulum
(RER), mitochondria, and golgi bodies in spermatocyte's cytoplasm. A prominent nucleolus and
a perforated nuclear membrane are features of a large nucleus
