Schistosoma haematobium and S. bovis are widespread schistosome species causing human and cattle schistosomiasis, respectively, in Africa. The sympatric occurrence of these two species and their ability to infect the same Bulinus intermediate snail hosts necessitates precise methods of identification of the larval stages. A rapid diagnostic 'mulitplex' one-step polymerase chain reaction protoco...

Eleven enzymes, which were used to compare South African S. mattheei and S. haematobium in a former study, were employed to study intraspecific variation within S. mattheei, using starch gel electrophoresis and iso-electric focusing where resolution in starch gel was poor. Acid phosphatase varied intraspecifically within S. mattheei in that the most southern population differed from the norther...

BACKGROUND Preventive chemotherapy against schistosomiasis has been implemented since 2005 in Mali, targeting school-age children and adults at high risk. A cross-sectional survey was conducted in 2010 to evaluate the impact of repeated treatment among school-age children in the highly-endemic region of Segou. METHODOLOGY/PRINCIPAL FINDINGS The survey was conducted in six sentinel schools in ...

BACKGROUND Diagnosis of urogenital schistosomiasis by microscopy and serological tests may be elusive in travelers due to low egg load and the absence of seroconversion upon arrival. There is need for a more sensitive diagnostic test. Therefore, we developed a real-time PCR targeting the Schistosoma haematobium-specific Dra1 sequence. METHODOLOGY/PRINCIPAL FINDINGS The PCR was evaluated on ur...

OBJECTIVE To evaluate the diagnostic accuracy of a circulating cathodic antigen (CCA) urine dipstick test for detecting Schistosoma mansoni and S. haematobium alongside an integrated rapid mapping survey in Southern Sudan. METHODS AND RESULTS A total of 373 children aged 5-16 years were included in the study. Of these 26.0% were infected with S. haematobium and 24.5% were infected with S. man...

BACKGROUND Schistosomiasis is a major parasitic disease affecting over 200 million people in the developing world with a further 400 million people at risk of infection. The aim of this study was to identify a single antigen from adult Schistosoma haematobium worms and subsequently use this antigen to study the development of schistosome-acquired immunity in a human population. METHODS The fu...

during 1979-77 a large number of kurdish populations in northern part of iraq temporarily immigrated to iran and settled in dezful area of khuzestan province, south-west iran. faecal examination of 3,263 samples for intestinal metazoan parasites and 1,154 urine samples for detecting schistosoma haematobium, infection were performed in different sex and age groups. the percentages of prevalent i...

FORD J. W. and BLANKESPOOR H. D. 1979. Scanning electron microscopy of the eggs of three human schistosomes. Znternational Journalfor Parasitology 9: 141-145. The surface of the eggs of Schistosoma haematobium, S. japonicum and S. mansoni, examined by scanning electron microscopy, are covered with microspines. The spines of S. mansoni and S. haematobium are essentially similar; however, in S. j...

With the current paucity of vaccine targets for parasitic diseases, particularly those in childhood, the aim of this study was to compare protein expression and immune cross-reactivity between the trematodes Schistosoma haematobium, S. bovis and Echinostoma caproni in the hope of identifying novel intervention targets. Native adult parasite proteins were separated by 2-dimensional gel electroph...

background: a parasitological survey of schistosoma haematobium and s. intercalatum infection among primary schoolchildren in capital area of democratic republic of são tomé and príncipe (drstp) was undertaken. methods: subjects with positive infection were confirmed by the detection of s. haematobium ova in the urine or s. intercalatum ova in the stool by using centrifugation concentration or ...
