HISTOPATHOLOGICAL ANALYSIS OF SCHISTOSOMA HAEMATOBIUM METAPLASIA OF THE URINARY BLADDER.

The present cross sectional study was carried out to analyze the histopathological changes in the urinary bladder affected by Schistosoma haematobium among 54 patients (aged between 20-60 years; 40 males, 14 females; 44 from rural, 10 from urban areas) attending Sohag University Hospital, Egypt from. October 2015 to March 2016. 10% formalin fixed biopsy specimens were examined from which sections of 5 jum were prepared and examined microscopically.

Pelopscreadium aegyptense n. gen., n. sp. and Pelopscreadium spongiosum (Bray & Cribb, 1998) n. comb., (Digenea: Lepocreadiidae), each from disjunct populations of the Yellow boxfish, Ostracion cubicus Linnaeus (Ostraciidae).

Bianium spongiosum Bray & Cribb, 1998 (Lepocreadiidae), described from the yellow boxfish, Ostracion cubicus Linnaeus (Ostraciidae), off Lizard Island, Queensland, Australia, possesses a combination of the following three morphological features which distinguishes it from all the other species currently assigned to the genus: (1) large internal patches of large cells forming sponge-like pads we have termed "pelops"("pelop" sing.) laterally in the forebody extending from near the anterior extremity to about the level of the intestinal bifurcation rather than possessing a scoop; (2) ceca that reach to near the posterior extremity where they end blindly without ani; and (3) a vitellarium which is present laterally but not dorsal to the ceca. Based on this we propose the erection of Pelopscreadium n.

Redescription of Pseudolepidapedon balistis Manter, 1940 and a biological variant (Trematoda: Acanthocolpidae) from the Red Sea fishes; Balistoides viridescens and Rhinecanthus assasi.

During a survey of Red Sea fish parasites, two trematodes belonging to the genus Pseudolepidapedon Yamaguti, 1938 were encountered: P. balistis Manter, 1940 was found in the small intestine of the fish Balistoides viridescens and was redescribed for the first time from Egypt; adding many detailed morphological and ultrastructural characters. The second trematode was found in the small intestine of the fish Rhinecanthus assasi and found to represent a biological variant of the previous species as it differs from it in its generally smaller dimensions, shape of suckers and pharynx and the testes.

Present status of protozoan pathogens causing water-borne disease in northern part of El-Minia Governorate, Egypt.

Little is known about the role of different water supplies in the diversity and public health significance of pathogenic protozoan parasites. Most of these organisms have been ubiquitous in waters worldwide. The numbers of waterborne infections indicate a significant risk for their transmission even by drinking water.

Unusual localization and presentation of non-visceral hydatid cysts: review article.

Echinococcosis is a major parasitic zoonosis of public health importance worldwide. This is particularly true in sheep-raising countries including Egypt. Therefore, it is very important to identify the significant risk factors of the diseases by reviewing studies done in the region in the past decade to help policy makers design appropriate control strategies.

Consumption hazards of cattle liver infected with Fasciola spp.: II. Experimental study on rats.

This study evaluated and revealed the consumption hazards of cattle liver infected with Fasciola spp. and revealed its effects on the serum estimation of liver enzyme (ALT) on experimental rats. A total of42 Wister albino rats were classified into 7 groups.

Histological and PCR xenomonitoring of culicine mosquitoes for filarial infestation in Sohag Governorate, upper Egypt.

The nematodes Wuchereria bancrofti and Brugia malayi; the principal etiologic agents of lymphatic filariasis are mosquito dependant in the biological transmission. Dirofilariasis is essentially a disease of canines which can also be transmitted to humans by culicine mosquitoes. The present work studied the histological and PCR xenomonitoring filarial infestation in culicine mosquitoes in Sohag Governorate.

Comparative study of the sensilla on antenna and maxillary palpsof five culicine mosquitoes in Sohag Governorate, Egypt.

Mosquitoes are unquestionably the most medically important arthropod vectors of disease. The maintenance and transmission of the pathogens that cause malaria, lymphatic filariasis, and numerous viral infections are absolutely dependent on the availability of competent mosquito vectors. Although the medical community has known for over a century the role played by mosquitoes in the transmission of malaria and lymphatic filariasis, these diseases continue to have a devastating influence on less privileged populations throughout the tropical and subtropical regions of the world.

Genetically confirmed Fasciola hepatogigantica n.sp.

Identification of liver fluke species cannot be achieved by clinical, pathological, coprological or immunological methods. However, the differential diagnosis between F. hepatica and F.

Studies on some metacestodes immunohistochemical response in mice as a model for human cysticercosis: II-THI type immune response in experimental Braintaenia crassiceps infected mice.

Neurocysticercosis is a serious zoonotic diseas, encountered worldwide, caused by the larval stage of Taenia solium. Due to the difficulties facing scientists to study the biological, histological and immunological effects of these larvae on the human brain, other cestodes with more or less similar larvae (Taenia crassiceps) were used. In brain infected mice, Th1 predominant cytokines were significantly detected.

Histochemical and ultrastructural studies on the calcareous corpuscles and eggs of Taenia taeniaeformis and Dipylidium caninum.

Calcareous corpuscles were noticed by several previous workers to be present in larval and adult cestodes without knowing their function. However, nothing was mentioned in the available literature about distribution of these corpuscles and their density, structure and composition in different parts of the body of different cestodes. Hence, in the present work, a comparative study of their distribution, density, histochemical and ultrastructural characters in different parts of the body was performed in Taenia taeniaeformis and Dipylidium caninum.

Development and hatching mechanism of Fasciola eggs, light and scanning electron microscopic studies.

Both light microscopy and scanning electron microscopy were used in the description. There were variable measurements of eggs from the same fluke and there was no relationship between the size of the fluke and size of eggs. Light microscopy revealed that the operculum has different shapes in Fasciola gigantica and F.

Comparative morphological studies on three Sarcocystis species in Sohag, Egypt.

Samples from the tongue, heart, oesophageal and skeletal muscles were collected from 100 cow and 100 buffalo from Sohag slaughterhouses. Macroscopic examination for sarcocysts was followed by microscopic ones on impression smears and compressed muscles. Histological sections and transmission electron microscope (TEM) studies were done on positive cases.
