Wuchereria bancrofti, Dirofilaria immitis, and Dirofilaria repens are filarial nematodes transmitted by mosquitoes belonging to Culex, Aedes, and Anopheles genera. Screening by vector dissection is a tiresome technique. We aimed to screen filarial parasites in their vectors by single and multiplex PCR and evaluate the usefulness of multiplex PCR as a rapid(More)
Various isolates of S. mansoni, originally showed marked diminished susceptibility to PZQ, were used in this work. These isolates were taken from patients not cured after two or three doses of the drug. They were passed in experimental mice and treated with sub-curative doses of PZQ to determine the effect of drug pressure on the offspring of these(More)
A double antibody sandwich ELISA technique, using a chromatography purified antisera against E. histolytica, G. lamblia and Cryptosporidium antigens, was applied to detect copro-antigens of the corrosponding parasites in 90 patients. All positive cases were diagnosed by parasitological examination and proved to have the infection solely. Beside the 90(More)
Oocysts of C. muris and the events of excystation using 0.5% sodium hypochlorite as excystation medium were described with light microscope. The response of the immunocompetent BALB/c mice against infection was studied using sera of orally infected mice at different periods postinoculation by indirect immunofluorescence antibody test using 1:150 FITC(More)
This cross sectional study was done in aswan Governorate to determine the prevalence of intestinal parasites and to identify the risk factors for infection in primary school children in this geographical area. The results will facilitate evaluation of the endemic level of different intestinal parasites and the determination of whether widespread or focal(More)
Wolbachia is an obligatory intracellular endosymbiotic bacterium, present in over 20% of all insects altering insect reproductive capabilities and in a wide range of filarial worms which is essential for worm survival and reproduction. In Egypt, no available data were found about Wolbachia searching for it in either mosquitoes or filarial worms. Thus, we(More)
Stool examination using modified Kato thick smear method was performed to detect Fasciola eggs and other parasites. Abdominal pain was the major presenting symptom (87.7%) followed by pallor (83.3%) and fever (16.7%). Anaemia and hepatomegaly were recorded in 77.7% of patients compared to 27.7% with splenomegaly. Abdominal ultrasonography revealed(More)
