Host-parasite relationship of S. mansoni and B. glabrata.

Experiments were conducted to study the host-parasite compatibility of various isolates of Biomphalaria glabrata snail and Schistosoma mansoni parasite isolates. A series of experiments conducted on 12 S. mansoni isolates have shown a range of infectivity potential for B. glabrata snail and 9 isolates of B. glabrata were found differentially susceptible to infection with S. mansoni trematode parasite.
