Schistosoma mansoni: Phytochemical Effect on Aquatic Life Cycle

Background: Two aspects need to be considered for schistosomiasis control: morbidity and transmission. In this context, many soluble substances have been tested and Euphorbia milii latex is one of the most promising Brazilian molluscicides. Phytochemical studies involving simulation of the applicability of this latex on all aquatic forms of the S. mansoni life cycle are rare in the literature. ...

Double impact: natural molluscicide for schistosomiasis vector control also impedes development of Schistosoma mansoni cercariae into adult parasites

BACKGROUND Schistosomiasis has been reported in 78 endemic countries and affects 240 million people worldwide. The digenetic parasite Schistosoma mansoni needs fresh water to compete its life cycle. There, it is susceptible to soluble compounds that can affect directly and/or indirectly the parasite's biology. The cercariae stage is one of the key points in which the parasite is vulnerable to d...

Effects of the Extracts of Euphorbia pulcherima and Atriplex nummularia on the Infectivity of Schistosoma haematobium to Bulinus truncatus Snails

Effects of extracts of Euphorbia pulcherima and Atriplex nummularia on infection rate and cercarial production of The Bulinus truncatus infected with Schistosoma haematobium, as well as on the free living stages of the parasite (miracidia and cercariae) besides biochemical parameters of the snail were studied. The results showed that the LC25 of the extracts of E. pulcherima and A. nummularia c...

Hybridization of Schistosoma mansoni and Schistosoma japonicum in mice.

Crossing experiments in mice with two human species of Schistosoma japonicum (Taiwan strain) and Schistosoma mansoni (Puerto Rican strain) were performed. The hybrid miracidia from the cross between female S. japonicum and male S. mansoni infected both Biophalaria glabrata and Oncomalania h. chiui. However, those from the reciprocal crossing could infect only B. glabrata. B. glabrata infected w...

DNA barcoding of schistosome cercariae reveals a novel sub-lineage within Schistosoma rodhaini from Ngamba Island Chimpanzee Sanctuary, Lake Victoria.

While Schistosoma rodhaini is typically considered a parasite of small mammals and is very scantly distributed in the Lake Victoria basin, it is known to hybridize with the more widespread Schistosoma mansoni, the causative agent of intestinal schistosomiasis. As part of broader parasitological and malacological surveys for S. mansoni across Lake Victoria, schistosome cercariae were harvested f...
