The genetic variation of compatibility in Biomphalaria glabrata and Schistosoma mansoni.
Interactions between different Biomphalaria glabrata stocks and Schistosoma mansoni strains were studied. A series of inbred stocks of B. glabrata were characterized as to genetic variations in susceptibility at different ages to a series of different S. mansoni strains. A series of inbred strains of S. mansoni were characterized as to genetic variations in infectivity for B. glabrata stocks at different ages. Also described is a process of selection for substrains from a single S. mansoni isolate that differ genetically in snail infectivity.
