Experimental infection trails of Lymnaea (cailliaudi) natalensis snails with miracidia of Fasciola hepatica revealed neither cercariae nor larval stages shed. Infection of white mice with metacercariae from field-collected snails proved to be negative for Fasciola eggs and immature juveniles or adults after 84 days post infection. The infection of eight(More)
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(More)
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.(More)
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. hepatica. Under normal laboratory(More)
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(More)
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. Hence, a total of 336 water samples(More)
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(More)
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(More)
We are hereby reporting a case where the eggs and adults of the mold mites; Tyrophagus putrescentiae (Shrank) and the trophozoites of Blastocystis sp. were found in stool of three years old child from Minia City, Egypt. Intestinal mite infection was diagnosed after repeated identification of mite' stages from six consecutive stool samples to exclude the(More)
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. Four groups were fed on raw and cooked cattle liver with various intensity of Fasciola spp.(More)
