in this paper the histopathological observation of the migratory phase of schistosome larvae (schistosomulae) in the laboratory animal were studied. the first tissue samples were taken from the skin of infected animals 30 minutes after exposure to the cercariae and continued daily up to 40 days post infection. the tissue specimens were taken from skin, liver. lung, lymph nodes, kidney, brain, b...

Schistosoma mansoni, which causes schistosomiasis has humans as the primary definitive host and mollusks Biomphalaria glabrata, B. straminea tenagophila intermediate hosts. The goal of this research was to undertake a malacological survey on watercourses in city Betim, using data provided by city´sHealth´s Department. were collected from pre-selected sites, examined for presence cercariae taxon...

central nervous system involvement arising from schistosomiasis is uncommon. it may be produced most fre­quently by schistosoma japonicum infection, but reports of s. mansoni presenting as an intracerebral mass lesion are particularly rare. the authors describe the case of a 35-year-old woman with a 3-month history of partial epilep­tic seizures and head­aches. she immigrated to egypt 4 years a...

Schistosomiasis is a Neglected Tropical Disease caused by trematode species of the genus Schistosoma. Both, autochthonous and imported cases urogenital schistosomiasis have been described in Europe. The present study focuses on eggs, considered pure S. haematobium genetic characterisation (intergenic ITS region rDNA cox1 mtDNA). A phenotypic eggs was made morphometric comparison with experiment...

Schistosoma mansoni is a parasitic fluke that infects millions of people in the developing world. This study presents the first application of population genomics to S. mansoni based on high-coverage resequencing data from 10 global isolates and an isolate of the closely-related Schistosoma rodhaini, which infects rodents. Using population genetic tests, we document genes under directional and ...

Pulmonary sparganosis mansoni is uncommon in general clinical practice, but prevalent in endemic foci. Pulmonary sparganosis mansoni shares some clinical and radiologic similarities that mimic other common pulmonary pathogens. Delayed diagnosis of pulmonary sparganosis mansoni can pose a significant hazard to the patient. Indeed, a history of ingesting uncooked stone cracks in endemic areas is ...

BACKGROUND Promising results have been reported for a urine circulating cathodic antigen (CCA) test for the diagnosis of Schistosoma mansoni. We assessed the accuracy of a commercially available CCA cassette test (designated CCA-A) and an experimental formulation (CCA-B) for S. mansoni diagnosis. METHODOLOGY We conducted a cross-sectional survey in three settings of Côte d'Ivoire: settings A ...

Infection caused by the trematode Echinostoma paraensei has been shown to interfere in the natural resistance to infection by Schistosoma mansoni. Biomphalaria glabrata is susceptible to infection, while Taim isolate Biomphalaria tenagophila is resistant to infection by S. mansoni. These two snail species were assessed for infection with E. paraensei two days after exposure to S. mansoni miraci...

The water rat, Nectomys squamipes, closely involved in schistosomiasis transmission in Brazil, has been found naturally infected simultaneously by Schistosoma mansoni and Echinostoma paraensei. Laboratory experiments were conducted to verify parasitic interaction in concurrent infection. It was replicated four times with a total of 42 water rats and essayed two times with 90 mice pre-infected w...

Fecal examination on 112 and a subset of 58 wild lions (Panthera leo) in the Serengeti National Park and the Ngorongoro Crater, Tanzania, East Africa revealed eggs, larvae, and protozoan cysts of 15 parasite taxa. The most prevalent were Spirometra sp. (63% prevalence), Taeniidae (58%), Ancylostoma sp. (56%), and a coccidian (53%). Three parasites were considered spurious. Of the hosts, 97.3% w...
