C. elegans immune response to Staphylococcus aureus, 4 hour exposure. Caenorhabditis elegans

Transcriptional profiling of C. elegans young adult worms exposed to pathogen Staphylococcus aureus for 4 hours versus age-matched worms exposed to control lab food E. coli OP50. The goal was to identify genes regulated in response to pathogen. The broader goal of study was to study evolution of pathogen response by comparing this expression profile to that obtained by exposing the nematode Pristionchus pacificus to the same pathogen. Other experiments which are a part of this study include expression profiling of C. elegans and P. pacificus on other pathogens including Staphylococcus aureus, Serratia marcescens, Xenorhabdus nematophila. Keywords: Expression profiling by array Overall design: One-condition experiments. C. elegans young adults: Exposed to Staphylococcus aureus versus exposed to E. coli OP50 : 4 hours. 4 biological replicates for each condition, including 2 dye-swaps.
