7Sgamma2b antibody was found attached to and in the integument of adult Schistosoma mansoni removed from CF1 white mice. With the techniques used, IgA, IgM, 7Sgamma1, 7Sgamma2a, 7Sgamma3, and C3 complement were not found to be attached to the integumental surfaces. 7Sgamma2b does not seem to fix C3, and it is suggested this antibody may be acting in enhancing and blocking roles which protect th...

In February 2015, a male patient from Eritrea with persistent abdominal pain and rectal bleeding was diagnosed with Schistosoma mansoni infection upon examination of a rectal biopsy. In May 2015, repeated stool microscopy identified S. mansoni infection in another Eritrean patient with abdominal pain and considerable eosinophilia (34%). Use of point-of-care circulating cathodic antigen (POC-CCA...

Schistosomiasis mansoni is a chronic liver disease that is endemic in rural areas of Egypt. Some patients may acquire infection and develop minimal complications, while others may develop severe complications and progress to portal hypertension and cirrhosis, especially if coinfected with viral hepatitis [1,2]. Egypt has the highest worldwide prevalence for the concomitant infection of schistos...

Schistosomes are endoparasites causing a serious human disease called schistosomiasis. The quantification of parasite genetic diversity is an essential component to understand the schistosomiasis epidemiology and disease transmission patterns. In this paper, we propose a novel assay for a rapid, low costly and efficient DNA extraction method of egg, larval and adult stages of Schistosoma manson...

Twelve Israeli travelers acquired schistosomiasis in Laos during 2002-2008, and 7 of them had acute schistosomiasis. The patients were probably exposed to Schistosoma mekongi in southern Laos, an area known to be endemic for schistosomiasis. Four possibly were infected in northern Laos, where reports of schistosomiasis are rare.

School-aged children suffer the most from schistosomiasis infection in sub Saharan Africa due to poverty and limited sanitary conditions. Mapping of disease burden is recommended and there is a need of updating prevalence data which is as old as 20 years in the Democratic Republic of Congo. An epidemiological and parasitological study was carried out in 2011 in the health zone of Kasansa. Six h...

BACKGROUND Schistosomiasis transmission is typically focal. Understanding spatial variations of Schistosoma infections and their associated factors is important to help to invent site-specific intervention strategies. METHODS A five-year longitudinal study was carried out prospectively in 12 natural villages, Guichi district of Anhui province. A GIS-based spatial analysis was conducted to ide...

background: schistosomiasis is one of the major communicable diseases of public health and socioeconomic importance in developing countries. this study assessed the situation of schistosomiasis among villagers of the new halfa agricultural scheme, sudan. methods: an epidemiological survey was carried out in three randomly selected residential sites: village 19, village 26 and talat shagrat camp...

Schistosoma mansoni causes morbidity in human beings, with the highest prevalence in rural sub-Saharan Africa. Prolonged S. mansoni infection with egg deposition in intestinal blood vessels leads to liver and spleen enlargement, and thus chronic morbidity. The objective of this study was to assess whether preschool-aged children develop severe S. mansoni-related morbidity. Parasitological, clin...

Even brief visits abroad may bring travellers into contact with pathogens against which they have no immunity. Though returning home apparently well, the travellers may be incubating an exotic illness with which they then present to their local doctor. We report a recent outbreak of acute Schistosoma mansoni infection that occurred in this way.
