The emergence of superspreaders depends on the acquisition and utilization of L-arabinose by S. Tm

(A) 129X1/SvJ mice infected with WT S. Tm, S. Tm^araBAD, or S. Tm⁰¹⁴⁸. S. Tm CFU/g feces quantified over 21 days. WT SL1344 infected mice (n = 25) represented in white, S. Tm^araBAD (n = 25) in blue, and S. Tm⁰¹⁴⁸ (n = 25) in pink. ^∗p < 0.05, ^∗∗p < 0.01 Multiple Mann-Whitney tests.

(B) Bar graph quantification of percent superspreaders at 7, 14, and 21 DPI. WT infected mice represented in gray bars, S. Tm^araBAD in blue, and S. Tm⁰¹⁴⁸ infected mice in pink.
