Probability to produce the second clutch according to female’s weight and treatment. Curves were calculated using average marginal effects of the absence/presence of the second clutch (0/1) related to the weight of females. Coloured distributions represent the confident interval for each treatment (95%). Abbreviations: control: never-injected females; NP: non-primed females LBP: females primed with sterile LB broth, SAP: females primed with 103 living S. enterica. SAP, NP and LBP received the LD50 injection.
