To assess if the priming effect can last for longer, we primed wild type but also Imd and Rel mutant flies 7 days prior to PA14 infection, and we noticed that priming had no significant effect in the survival rates of any of the genotypes tested: Canton S (P=0.0726), Rel (P=0.9163), Imd (P=0.0663) (Figure 6). Here, REL is linked to infection.
