schistosomiasis is the second most common parasitic cause of death, after malaria. biomphalaria glabrata is a fresh water snail with medical importance since it is the intermediate host of schistosoma mansoni, an agent of schistosomiasis. the internal defense system of b. glabrata snails is mostly represented by circulating elements of the hemolymph, hemocytes, which are important factors in fi...

background: the aim of this study was to evaluate the possible use of biomphalaria alexandrina snail antigens in diagnosis of schistosomiasis mansoni using enzyme linked immunolectrotransfere blot (eitb). methods: s. mansoni adult worm crude antigens (awa), feet and visceral humps of b. alexandrina and bulinus truncatus were used. hyperimmune mice sera (his) versus each antigen were prepared fo...

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...

In endemic regions, Mansoni schistosomiasis is responsible for high morbidity-mortality rates due to diseases associated with infestation of the hepatic system. Genital involvement caused by Mansoni schistosomiasis is rare. We report the first case of Mansoni schistosomiasis in the seminal vesicle, which was diagnosed incidentally by means of histopathological study of the prostate and seminal ...

background: schistosomiasis and soil transmitted infection is a major health problem of children from rural areas of developing countries including yemen. in an attempt to reduce this burden, the ministry of public health and population in yemen established in 2002 a programme for schisto-somal, soil transmitted infection control that aimed to reduce morbidity and prevalence rates of schistosom...

BACKGROUND Symptomatic acute schistosomiasis mansoni is a systemic hypersensitivity reaction against the migrating schistosomula and mature eggs after a primary infection. The mechanisms involved in the pathogenesis of acute schistosomiasis are not fully elucidated. Osteopontin has been implicated in granulomatous reactions and in acute hepatic injury. Our aims were to evaluate if osteopontin p...

INTRODUCTION Schistosomiasis mansoni is an endemic disease in underdeveloped or developing countries. The study aimed to define schistosomiasis prevalence in Bom Gosto village, Tutóia, Maranhão, in 2008 and detect intermediate host occurrence. METHODS A survey of data from stool samples examined by the Municipal Department of Health and National Health Foundation was conducted. Next, 60 snail...

Schistosomiasis mansoni is usually a chronic infection that leads to long-term, systemic exposure to schistosome antigens. Experimental Schistosoma mansoni infection is associated with immunoregulatory mechanisms, including T regulatory cells (Treg) that may help control morbidity and dampen resistance to re-infection. We now show that some schistosomiasis mansoni patients have high proportions...

Egyptian subjects living in areas endemic for Schistosoma mansoni or Schistosoma haematobium were selected on the basis of their apparent extremes of resistance or susceptibility to schistosomiasis and examined for T and B cell responses against the major electrophoretically resolved protein species from soluble adult worm extracts. A 42-kDa band was specifically recognized by a significant maj...

TO THE EDITOR—We read the photo quiz authored by Bagdure and Khasawneh with interest [1]. The authors described a case of schistosomiasis colitis caused by Schistosoma mansoni, which was diagnosed after review of hematoxylin-eosin– stained colonic biopsy sections. This case emphasizes the challenges associated with obtaining a laboratory diagnosis of schistosomiasis based on examination of ova ...
