Table 1. Physiological ratios of tissue metal concentrations.

Zn(II)/Mn(II) Ratio
Sample Naïve (n = 5) Infected (n = 10) Fold Change*
Brain 33 93 2.8
Lung 39 96 2.4
Nasopharynx 63 336 5.3
Blood serum 37 905 24.4

*The statistical significance of the differences between the metal ion concentrations before (naïve) and after (infected) infection for all samples were analyzed using a two-tailed unpaired t-test. P-values for all analyses were at least <0.05.
