Human schistosomiasis is a common parasitic disease endemic in many tropical and subtropical countries. One barrier to achieving long-term control of this disease has been re-infection of treated patients when they swim, bathe, or wade in surface fresh water infested with snails that harbor and release larval parasites. Because some snail species are obligate intermediate hosts of schistosome p...

Schistosomiasis - a parasitic disease that affects over 200 million people across the globe - is primarily transmitted between human definitive hosts and snail intermediate hosts. To reduce schistosomiasis transmission, some have advocated disrupting the schistosome life cycle through biological control of snails, achieved by boosting the abundance of snails' natural predators. But little is kn...

Planktonic samples were collected from two habitats in Giza Governorate, Kafr Hakem (+ snails) and Sadek canals (snails). Oscillatoria accuminata and Lyngbya perelegans were collected from the first location, while Phormidium valderianum, Spirogyra sp and Lyngbya perelegans were separated from the second one. Nostoc muscorum was obtained from Theodor Bilharz Research Institute (TBRI) and used i...

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...

This study aims to investigate macroinvertebrate assemblage structure and composition across the three major waterbody types (temporary rivers, depression wetlands and semi-permanent dams) of the Eastern Cape Karoo, and to identify important environmental and spatial correlates of macroinvertebrate assemblage composition in the region. A total of 33 waterbodies (9 dams, 13 depression wetlands a...
