| tissue responses exhibited by biomphalaria alexandrina snails from different egyptian localities following schistosoma mansoni exposure. | snails' susceptibilities to infection with schistosoma mansoni were determined through observation of infection rates, total cercarial production and tissue responses of the first generation (f1) of biomphalaria alexandrina snails, originally collected from different egyptian governorates (giza, fayoum, kafr el-sheikh, ismailia and damietta) and responses were compared between groups. the emergence of cercariae for a 3-month period and the calculation of survival and infection rates, in control ... | 2011 | 21295031 |
| school non-enrollment and its relation with health and schistosomiasis knowledge, attitudes and practices in rural egypt. | children who are not enrolled in school are deprived of schistosomiasis treatments delivered through school health programmes. we explored perceptions of barriers to school enrolment and health and schistosomiasis knowledge, attitude and practices among 58 enrolled and 41 non-enrolled children and 80 adults in a village in el-fayoum governate, egypt. economic factors, cultural factors and the school system were perceived as barriers. maternal education had a significant role in enrolment. non-en ... | 2005 | 16602459 |
| efficacy of myrrh in the treatment of schistosomiasis (haematobium and mansoni) in ezbet el-bakly, tamyia center, el-fayoum governorate, egypt. | schistosomiasis remains a public health problem in egypt, despite the continuous control effort. most of the anti-schistosomal drugs have deleterious side effects or low efficacy. this necessitates a search for new safe and effective drug. a field survey was done in ezbet el-bakly (tamyia center) el-fayoum governorate to determine the magnitude of schistosomiasis haematobium and mansoni and to evaluate the efficacy of mirazid (the oleo-resin extract from myrrh of commiphora molmol tree, family: ... | 2004 | 15287168 |
| the epidemiology of schistosomiasis in egypt: fayoum governorate. | health questionnaires and parasitologic examinations of urine and stool were performed upon a stratified random sample of 7,710 individuals from 1,109 households in 21 rural communities in fayoum governorate, egypt in 1992 to investigate the prevalence of, risk factors for, and changing pattern of, infection with schistosoma sp. in the governorate. a subset, every fifth household, or 1,038 subjects, had physical and ultrasound examinations to investigate prevalence of, and risk factors for, morb ... | 2000 | 10813501 |
| developing strategies to control schistosomiasis morbidity in nonenrolled school-age children: experience from egypt. | schistosomiasis is a major health problem in school-age children in much of the tropical world. they harbour the most intense infections for both schistosoma mansoni and s. haematobium. in egypt, the ministry of health and population (mohp) has implemented a successful school-based treatment programme in which children are screened and those found to be infected treated with praziquantel. high nonenrolment rates in some rural areas have a negative impact on the coverage of this programme and on ... | 1999 | 10499078 |
| invasion of the nile valley in egypt by a hybrid of biomphalaria glabrata and biomphalaria alexandrina, snail vectors of schistosoma mansoni. | two years (1996-1997) of systematic survey showed that a hybrid of biomphalaria glabrata and biomphalaria alexandrina has invaded the irrigation and drainage systems in the nile delta and the valley nor the of el-menya. however, the infestation of water courses by and the population density of this snail were variable in various localities. the infestation rate ranged between 7.1% in el-fayoum governorate and 52.6% in el-dakahliya governorate and the snail density from 2 snails/site to 69.7 snai ... | 1998 | 9707685 |
| is schistosoma mansoni replacing schistosoma haematobium in the fayoum? | schistosoma mansoni is progressively replacing s. haematobium along the nile river in egypt. this change has occurred in the past 15-20 years following construction of the aswan high dam in the 1960s. the cause is a shift in relative abundance of the snail vectors biomphalaria alexandrina and bulinus truncatus. biomphalaria is increasing while the latter has disappeared from a village in the fayoum where formerly only schistosomiasis haematobia was endemic. a cross-sectional household survey in ... | 1993 | 8279637 |
| the epidemiology of schistosomiasis in egypt: summary findings in nine governorates. | health questionnaires and parasitologic examinations of urine and stool were evaluated from a stratified random sample of 89,180 individuals from 17,172 households in 251 rural communities in 9 governorates of egypt to investigate the prevalence of, risk factors for, and changing pattern of infection with schistosoma sp. in egypt. a subset, every fifth household, or 18,600 subjects, had physical and ultrasound examinations to investigate the prevalence of and risk factors for morbidity. prevalen ... | 2000 | 10813505 |
