Figure 1. Experimental design for the simultaneous comparison of haemocyte gene expression in Biomphalaria glabrata strains upon exposure to Schistosoma mansoni.

A. Resistant (R) and susceptible (S) strains of B. glabrata were exposed to S. mansoni (E) or kept unexposed as controls (C) B. Microarray hybridizations: 16 array hybridizations in double loop design with dye swaps were performed.
