Abstract
This is the first time to identify the nematode Procamallanus (Procamallanus) pseudolaeviconchus in Egypt from the stomach and intestine of the Nile catfish Clarias gariepinus. In this study, the female reproductive system has been studied in detail for the first-time using phase contrast microscopy. It consists of a single ovary, an oviduct, a seminal receptacle, a uterus, a vagina, and a vulva. The ovary appears telogonic and differentiated into 3 main regions namely germinal, growth and maturation zones. In the proximal widened (sac-like) region of the ovary, the oocytes reach their maximum maturation and size and assume cuboidal form. Four oocyte forms could be detected in the sac-like region of the ovary. In most forms, the nuclear membrane is surrounded by a thin layer of dense material and the cytoplasm contains different types of secretory bodies and vesicles. In between, the different forms of mature oocytes, lie non-nucleated cytoplasmic regions, some of them have no cytoplasmic inclusions while others contain dense granular bodies. Moreover, relatively large, spherical membrane-bound vacuoles, containing secretory bodies and vesicles, are seen in between the mature oocytes. There are constrictions between the ovary and oviduct, the oviduct and seminal receptacle and between the seminal receptacle and uterus.
