MPP2 and infection: Among the 11 putative genes identified in the murine model, six were found to have human orthologues that exhibited significantly different levels of expression in patients with S. aureus BSI as compared to healthy subjects with no infection (n = 43): Dcaf7 (0.85fold; p = 0.003), Dusp3 (1.73 fold; p<0.0001), Fam134c (0.75fold; p<0.0001), Psme3 (0.78fold; p<0.0001), Mpp2 (1.21fold; p = 0.004), and Slc4a1 (0.81fold; p = 0.012) (Figure 3A).
