Can the freshwater crayfish (Procambarus clarkii) help control schistosomiasis and fascioliasis in Egypt
TLDR
The present study is providing encouraging indication of the possible overcoming schistosomiasis and fascioliasis in Egypt by the freshwater crayfish Procombarus clarkii.Abstract:
ab experiments and field survey have been carried out to investigate the impact and the relationship between the exotic crayfish; Procambarus clarkii and Schistosoma and Fasciola vector snails in Egypt. In the Lab, several species of freshwater snails, fish and aquatic plants were reported to serve as food for the freshwater crayfish. In the field, a survey for the crayfish and freshwater snails has been conducted at several irrigation channels in Qalyobiya, Ismailia and Behera governorates, which had been previously surveyed during 1990s. The results of the experimental Lab indicated that the vector snails; Biomphalaria alexandrina, Bulinus truncatus and limnaea natalensis were the preys of first choice for the crayfish. The field surveys showed high reduction and sometimes complete disappearance of vector snails in irrigation channels, which have been invaded by Procambarus clarkii, while in water courses which do not harbor the crayfish, such as El Manayef drain and Fayed canal (West of Suez Canal), high densities of these vector snails were recorded. The present study is providing encouraging indication of the possible overcoming schistosomiasis and fascioliasis in Egypt by the freshwater crayfish Procombarus clarkii.read more

Impact of the freshwater operculate snail Melanoides tuberculata on Survival and Egg Production of the planorbid snail Bulinus truncates and on its transmission of Schistosoma haematobium Infection
TL;DR: The effects of Melanoides are additive and thus could lead to considerable depression in schistosomiasis transmission, and supports the utilization ofMelanoides in the biocontrol of schistOSomiasis in Egypt.

Schistosomiasis in newly reclaimed areas in Egypt. 1-distribution and population seasonal fluctuation of intermediate host snails.
TL;DR: Two newly reclaimed areas located west & east of Suez Canal, namely El Manayef area and El Morra area, were studied for patterns of distribution and population seasonal fluctuation of Biomphalaria alexandrina and Bulinus truncatus, the intermediate host snails of Schistosoma mansoni and S. haematobium.

Schistosomiasis in newly reclaimed areas in Egypt. 2--Patterns of transmission.
TL;DR: The results confirm the occurrence of transmission of both Schistosoma mansoni and S. haematobium since infected snails of both species were recovered in these areas, which proves that reclamation of parts of the desert utilizing Nile water had led to spread of schistosomiasis to these areas.

Ecology of Biomphalaria alexandrina the snail vector of Schistosoma mansoni in Egypt.
TL;DR: Results shown that the spreading patterns of snails along canals are changeable because of water current and irrigation activities, and double sampling of 50% of sampling sites the next day should be satisfactory as a quality control system in snail population studies.
