Much is known regarding the host-parasite interactions of these two organisms, and the B. glabrata embryonic (Bge) cell line has been an invaluable resource in these studies. The B. glabrata BB02 genome sequence was recently released, but nothing is known of the sequence variation between this reference and the Bge cell genome, which has likely accumulated substantial genetic variation in the ~50 years since its isolation. Here, we report the genome sequence of our laboratory subculture of the Bge cell line (designated Bge3), which we mapped to the B. glabrata BB02 reference genome. Single nucleotide variants (SNVs) were predicted and focus was given to those SNVs that are most likely to affect the structure or expression of protein-coding genes. Furthermore, we have high...

With the World Health Organization's goal to eliminate schistosomiasis as a global health problem by 2025, there is now renewed emphasis on snail control. Here, we characterize the genome of Biomphalaria glabrata, a lophotrochozoan protostome, and provide timely and important information on snail biology. We describe aspects of phero-perception, stress responses, immune function and regulation of gene expression that support the persistence of B. glabrata in the field and may define this species as a suitable snail host for S. mansoni. We identify several potential targets for developing novel control measures aimed at reducing snail-mediated transmission of schistosomiasis.
