Schistosomiasis is an important parasitic disease that infects humans. Among the main species of schistosomes infecting humans is Schistosoma mansoni and S. haematobium. Snails of various genera, such as Biomphalaria alexandrina and Bulinus truncates, act as intermediate hosts and play a major role in the transmission of schistosomes. Transmission from human to snail is under the influence of t...

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...

Molecular interplay during snail-schistosome interactions is poorly understood and there is much to discover concerning the effect of snail host molecules on molecular processes in schistosomes. Using the Biomphalaria glabrata - Schistosoma mansoni host-parasite system, the effects of exposure to haemolymph, derived from schistosome-resistant and susceptible snail strains, on protein tyrosine p...

Schistosomiasis has been classified as a category II disease after malaria in importance targeted tropical disease. Praziquantel (PZQ) which is the chemotherapeutic agent of choice against adult worms, already faces drawback drug resistance some Schistosoma isolates. Therefore, searching for new alternative drugs intention many researchers. In current study, effect different doses 6.25, 12.5, 2...

In the present study, we examined the effect of amphotericin B on larval stages (miracidia and primary sporocyst) of the helminth Schistosoma mansoni, the causative agent of human schistosomiasis. Amphotericin B (AmB) is a polyene macrolide that disturbs the function of the cell membrane; it is widely used as prophylactic antimycotic agent in in vitro culture. We show for the first time that S....

23 In the present study, we examined the effect of amphotericin B on larval stages (miracidia and 24 primary sporocyst) of the helminth Schistosoma mansoni, the causative agent of human 25 schistosomiasis. Amphotericin B (AmB) is a polyene macrolide that disturbs the function of the cell 26 membrane; it is widely used as prophylactic antimycotic agent in in vitro culture. We show for the 27 fir...

MCKINDSEY, C.W., and MCLAUGHLIN, J.D. 1994. Transmission of Cyclocoelum mutabile (Digenea) to snails: the influence of temperature on the egg and miracidium. Can. J. Zool. 72: 1745 175 1. This study examined the survival and hatching dynamics of eggs of the digenean Cyclocoelum mutabile and the survivorship and infectivity of the miracidia under different temperature regimes. Hatching did not o...

In the present study, the efficacy of 6 different species of medicinal plants belonging to 5 different families against Biomphalaria alexandrina snails and Schistosoma mansoni stages were examined. During screening test of water suspension and methanol extract, results revealed that Oreopanax reticulatum (Family: Araliaceae) had the strongest molluscicidal activity against Biomphalaria alexandr...

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.

The attraction exerted by Biomphalaria glabrata infected with Angiostrongylus costaricensis on Schistosoma mansoni miracidia of the BH strain was tested, using a glass apparatus composed by two circular chambers connected to a channel. One mollusk or a sample of a snail conditioning water (SCW) was placed in one of the chambers, randomly selected, and the remaining of the apparatus was filled w...
