The host-parasite relationships of a Schistosoma haematobium isolate, originating from Niger, and the white mouse are described. Swiss OF1 albino mice were exposed individually to 200 cercariae and worms were recovered 9, 12, 16 and 20 weeks post infection. The mean worm returns ranged between 10.54 and 13.05% and did not alter significantly between 9 and 20 weeks post infection. The sex ratio ...
We report about field and theoretical studies on the ecology of the aquatic snails (Bulinus spp. and Biomphalaria pfeifferi) that serve as obligate intermediate hosts in the complex life cycle of the parasites causing human schistosomiasis. Snail abundance fosters disease transmission, and thus the dynamics of snail populations are critically important for schistosomiasis modeling and control. ...

Molluscs are among the most important group of faunistic diversity in aquatic habitats. In this paper, abundance, species diversity and some of the morphological traits such as body length and whorl numbers of the mollusks found in three rivers, Hablehrood, Jajrood and Lar in east Tehran, through three seasons of autumn, spring and summer were studied.
