The Establishment of a Strain of Australorbis glabratus Which Combines Albinism and High Susceptibility to Infection with Schistosoma mansoni

Abstract

An albino strain of A. glabratus highly susceptible to a Puerto Rican strain of S. mansoni was devel-oped from pigmented susceptible and albino resistant strains. The new strain was established as a colony following 10 consec-utive generations of selfing after the initial cross between the parent strains. Small daughter sporocysts can be seen moving about in the live infected snail because of the relative trans-parency of the latter.
