Virulence of geographically different Cryptosporidium parvum isolates in experimental animal model.

Cryptosporidium parvum is a coccidian parasite which causes gastrointestinal disease in humans and a variety of other mammalian species. Several studies have reported different degrees of pathogenicity and virulence among Cryptosporidium species and isolates of the same species as well as evidence of variation in host susceptibility to infection. The study aimed to investigate infectivity and virulence of two Cryptosporidium parvum “Iowa isolate” (CpI) and a “local water isolate” (CpW).

SODIUM DODECYL SULPHATE POLYACRILAMIDE GEL ELECTROPHORESIS (SDS-PAGE) FOR DIFFERENTIATION OF DIFFERENT SCHISTOSOME AND FASCIOLID SPECIES.

Fasciola and Schistosoma spp. are digenetic trematodes that have a major detrimental impact on human health worldwide. It is not unusual to find common molecules among parasites of different species, genera, or phyla.

Prevalence of schistosomiasis among patients attending Qena General Hospital over the years 2011 and 2012.

Schistosomiasis is a public health problem in Egypt. To detect the prevalence of schistosomiasis in Qena Governorate, 1601 urine and stool samples of patients attending Qena General Hospital were examined of whom 1601 patients had urinary symptoms and 893 patients had dysentery and bloody stool. Sheets were filled out on each patient.

Comparative study between non lethal and lethal strains of Plasmodium yoelii with reference to its immunological aspect.

Innate immunity has an important role in the protection against malaria. To clarify the effect on non lethal and lethal strain of Plasmodium yoelii, comparison between two groups of C57BL/6 mice infected with 10(4) parasitized RBCs was performed. Liver and spleen mononuclear cells were isolated and analyzed by flow cytometry.

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.
