An evolutionarily conserved transcriptional response to viral infection in Caenorhabditis nematodes

Background Caenorhabditis elegans is a powerful model organism for probing many biological processes including host-pathogen interactions with bacteria and fungi. The recent identification of nematode viruses that naturally infect C. elegans and Caenorhabditis briggsae provides a unique opportunity to define host-virus interactions in these model hosts.
