Relative gene expression changes of the seven antimicrobial enzymes and peptides, and ins-7 genes in C. elegans , fed on P. luminescens for 6, 12 and 24 hours. Values are means ± SE from at least three independent experiments. The significant differences were determined by Student’s t-test, compared to a normalized value of 1.0 for control C. elegans fed on E. coli OP50. *P < 0.05; **P < 0.005.
