A. Total number of transcripts exhibiting increased (above zero line) or decreased (below zero line) expression in BS-90 snails immunocompromised by irradiated <i>E. paraensei</i> before challenge with <i>S. mansoni</i> (see key for bar colors on figure).

<p>Analysis compared experimental snails at 2 or 4 days post <i>S. mansoni</i> challenge to time and size matched control BS-90 snails exposed to irradiated <i>E. paraensei</i> only. Of the 6 individual snails analyzed at each time point, 3 were successfully infected with <i>S. mansoni</i>, and 3 remained resistant. B) Expression profiles of transcripts deemed important to <i>S. mansoni</i> resistance in snails. Fold-changes in expression of snails suppressed by irradiated <i>E. paraensei</i> before <i>S. mansoni</i> challenge are compared to snails exposed only to irradiated <i>E. paraensei</i>. Bars represent standard error (n = 3).
