Each open circle represents one mouse fed control diet and each black circle represents one mouse fed pAOS diet. Bars represent median values. Lines indicate differences between each day of infection within each dietary mice group or between the pAOS and control mice groups on the same day of infection.; The p-values are based on the Mann-Whitney U test. *, <i>P</i><0.05; **, <i>P</i><0.01
