Following publication of the original article in Gut Pathogens [1], it was brought to our attention that graphs for Figures 6 and 8 were interchanged and are therefore incorrect.

Please find the correct Figs. 6 and 8 below. Also in the Results and Discussion section titled “SPI-13 does not contribute to the survival of S. Enteritidis in chicken macrophages,” the uptake of the ΔSPI-13 mutant is incorrectly described as having a higher uptake in HD11 macrophages compared to the WT strain. We observed higher uptake of the WT strain in HD-11 cells. We apologize for the inconvenience this may have caused.

Fig. 6

Deletion of SPI-13 results in increased uptake and reduced survival (2 and 20 h) in mouse RAW264.7 macrophages. Bars represent mean percent of each phenotype from three biological replicates ± SEM. Significant differences were determined using two sample t test not assuming equal variances (*P < 0.05)

Fig. 8

Deletion of SPI-13 does not affect survival in HD11 chicken macrophages. Macrophages were infected at an MOI of ~20 and the mean percent uptake and percent survival at 2 and 20 h post infection was determined from three biological replicates. Significant differences were determined using two-sample t test not assuming equal variances (*P < 0.05)
