ADSL and infection: As shown in Figure 3B, unlike the wt Bt407 strain, which is highly resistant to the Relish-dependent AMPs response in flies thus killing wt, ΔAMPs and relish mutants with the same kinetics (approximately 100% of lethality 12 h post-infection), the fliK mutant displays an attenuated virulence in immunocompetent flies (37% of lethality at 12 h post-infection) while remaining fully virulent in immunodeficient flies sharing the same lethality kinetics with its parental strain (Figure 3B).
