Immunodiagnostic methods based on the detection of antibodies continue to be the most effective and practical methods for the diagnosis of imported schistosomiasis. Schistosoma bovis is a species whose final natural hosts are bovines, ovines, caprines, and small wild ruminants. Different studies have demonstrated the analogies existing between S. bovis and other Schistosoma species which affect...

Schistosomiasis is a debilitating disease caused by trematode worms of the genus Schistosoma. Three members Schistosoma mansoni, Schistosoma haematobium, and Schistosoma japonicum are responsible for the great majority of human infections. Schistosomiasis is widespread in sub-Saharan Africa, several countries of the Mid‐ dle East, South America, and South-East Asia. Vaccination against the infe...

BACKGROUND The global distribution map of schistosomiasis shows a large overlap of Schistosoma haematobium- and S. mansoni-endemic areas in Africa. Yet, little is known about the consequences of mixed Schistosoma infections for the human host. A recent study in two neighboring co-endemic communities in Senegal indicated that infection intensities of both species were higher in mixed than in sin...

in the field trials of slow-release nollusicide, copper content mcckechnie chemical inc. 30 cuso4 5h2o or 7.5 cupellet/sinking material 7 days release life were tested against the common aquatic snails bulinus truncatus, physa acuta and lymnaea gedrosiana in stagnant water bodies in khuzestan province, south-west of iran. snail densities before treatment and 7 days after mollucicide application...

background: trematodes belonging to the genus schistosoma cause schistosomiasis. the relationship between schistosomes and their intermediate hosts varies among snails. this study investigated the effects of s. japonicum on its snail host, oncomelania hupensis, and cercarial release rythmicity of s. japonicum and the effects of light on it. methods: : seven groups of o. hupensis (n = 40 each) w...

A large Schistosoma mettheei ovum containing two miracidia was recovered from a squash preparation of the liver of an experimentally infected hamster. When observed, the miracidia were motile and facing in opposite directions.

Trioxaquine PA1259 is an efficient drug on larval- and adult-stage schistosomes, able to alkylate heme inside worms treated with it, leading to the formation of covalent heme-drug adducts. Such a mechanism, similar to one reported for other trioxaquines in Plasmodium, indicates that heme may be a common target of these trioxane-based drugs in different blood-feeding parasites.

The relationship between bladder tumors and Schistosoma haematobium is well known, but only sporadic cases of bladder infection due to Schistosoma mansoni have been reported. In this case, a 48-year-old woman with macroscopic hematuria, dysuria and a palpable abdominal mass was investigated. Ultrasound showed a large exophytic mass in the bladder. Transurethral resection of the bladder revealed...

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...
