Ultrastructural study of the body surface and the flame cell of oochoristica sp [cestoda: anoplocephalidae]

Ultrastructural studies on the body surface of the adult tapeworm Oochoristica sp. revealed that all the strobilar surface including the scolex and the adhesive surfaces of the suckers are covered with long filamentous microtriches. Using scanning and transmission electron microscopes, the basic morphology of the microtriches was studied and found to be similar to those described in other cestodes, but differs in having a relatively long basal regions. The flame cell was also described

Larval stages of digenetic trematodes of pirenella conica from Deversoir Ismailia, Egypt

Two cercariae are described from the prosobranch snail Pirenella conica collected from Deversoir marine water, Ismailia, Egypt. One of the cercariae is prepleurolophocercous group, belonging to genus Stictodora, while the second is a Ephemera monostome cercaria. The latter is a new record for Pirenella conica snail in marine water from Ismailia. Details are presented on the morphology and behavior of the cercariae and rediae, as well as of their development within the snail, with discussion and comparison of previously described cercariae. The incidence of single [pure] and simultaneous mixed [double] infection of snail with two larval trematodes were also Determined

Studies on larval digenetic trematodes of xiphidiocercariae from some Egyptian fresh water snails

Six xiphidiocercariae are described from seven Egyptian snails, includes Cleopatra bulimoides, Malanoides tuberculata, Lymnaea caililaudi, Bulinns truncatus, Biomphalaria alexandrina and Lanistes carinatus collected from Giza [Abou Rawash] and Qualiobyia [Qualiuob]. Details are presented on the morphology, behavior of the cercariae, as well as other larval stages within the snails, with discussion and comparison between the previously described cercariae

Studies on the nematode parasites from Egyptian rodents 1- spirurid nematodes

Three spirurid nematode species have been collected from Egyptian rodents in Giza province. Streptopharagus kuntzi was collected from stomach and small intestine of Rattus ratus, R. norvegicus, Arvicanthis niloticus and Gerbillus gerbillus. Protospirura muris and P. marsupialis have also been collected from A. niloticus, R. rattus and R. norvegicus but P. marsupialis was collected only from the stomach while P. muris collected from stomach and small intestine. P. marsupialis was firstly recorded in Egypt during this work and no males of this species were collected. Females of S. kuntzi and P. muris showed marked dominance over males. Streptopharagus sudanensis and S. kuntzi are placed in synonomy
