the laboratory infection of lymnaea gedrosiana with 2,5 and 10 miracidia of fasciola gigantica resulted in infection rates of 20%, 40% and 69%, respectively, with a prepatent period of 66-88 days. there was a significant difference in infection rate between the snails infected with 2 and those with 10 miracidia (p<0.05). at 92 days post- infection there was 25% to 33.3% of live snails still har...

 ABSTRACT Background: Schistosoma haematobium is a parasite that is carried by freshwater snails and induces gastrointestinal and urinary disease, depending on its species. In Khoozestan, one of the provinces in Iran, schistosomiasis was endemic. This study reports the results of schistosomiasis control in this region. Methods: From 1981 to 2001 nearly 650 villages and 20 cities were under surv...

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...

Schistosomiasis or bilharziasis is a disease caused by Schistosoma. When infecting men the most common parasites are Schistosoma mansoni, Schistosoma japonicum and Schistosoma haematobium. The Schistosoma mansoni is the only endemic parasite in Brazil. We present a case of testicular schistosomiasis simulating malignancy. The case was treated successfully by excisional biopsy and praziquantel t...

Studies on parasite-induced immunoregulatory mechanisms could contribute to the development of new therapies for inflammatory diseases such as type 2 diabetes (T2D), which is a chronic inflammatory disease characterized by persistent elevated glucose levels due to insulin resistance. The association between previous Schistosoma infection and T2D has been confirmed-Schistosoma infection and Schi...

The cystatin family comprises cysteine protease inhibitors distributed in 3 subfamilies (I25A-C). Family members lacking cystatin activity are currently unclassified. Little is known about the evolution of Schistosoma cystatins, their physiological roles, and expression patterns in the parasite life cycle. The present study aimed to identify cystatin homologs in the predicted proteome of three ...

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...

Schistosoma are dioecious digenetic trematodes carrying a large (270 Mb) genome. Gaining knowledge about the genome of these parasites is of importance for the understanding of their biology, mechanisms of drug resistance and antigenic variation that determine escape from the host's immune system. This review will provide an update on the Schistosoma Gene Discovery Program, which is part of the...

Adults of Schistosoma edwardiense Thurston, 1964, were recovered from Hippopotamus amphibius in the Kruger National Park. Small round to oval Schistosoma margrebowiei-like eggs, presumed to be those of S. edwardiense, were found fairly frequently in the faeces of infected hippopotami together with a few Schistosoma haematobium-like eggs the identity of which remains uncertain. Biomphalaria sp.,...
