A rotten apple was the source of virally infected C. elegans, as reported in this issue by Félix et al. (e1000586). The small pictures making up the photomosaic show Caenorhabditis nematodes, some of which are infected as revealed by FISH staining of viral RNA. C. elegans mounts a small-RNA response that acts in antiviral defense, and this immune response varies among C. elegans wild isolates.
