Course of simulated S. Enteritidis outbreaks in groups of 200 laying hens: baseline simulation scenario A. Top panels: % culture-positives with time; lower panels: % egg-positives with time. Simulations: the white line denotes the 50th percentile of simulation results for every sampling day, within the 90% grey area. Experimental data: "X" denote cloacal swab culture-positives or egg-positives, respectively; "O" denote proportion positive cecal swab culture (experiment 3 only).
