[2] Experiments confirmed it to be a host of the Schistosoma parasites, while the Bulinus truncatus freshwater snail has been known much longer as a carrier of schistosomiasis.

[5] Likewise, in the laboratory, snail specimens from Portugal and Salamanca were found to be very susceptible to infections by Schistosoma bovis strains gathered from the Salamanca region, but the 1977 study urged a prevalence survey of free-living snails.

P. metidjensis is immune to experimental infection with hybrid parasites collected in Corsica that contain 23% genetical material from S.

[6] In a 2007 study carried out in Morocco, the snail was found in larger altitudes, and not in man-made water bodies like canals and artificial lakes.

It tolerated a wide range of electrical conductivities (120 to 3650 microsieverts/cm) and up to 1.1 grams of chlorides per liter.
