<i>S</i>.Typhimurium infection of <i>Il17ra^−/−</i> mice.

<p><i>Il17ra^−/−</i> mice, <i>Il17ra^+/−</i> littermates and C57BL/6 control mice were pretreated with streptomycin and infected for 12 hours with <i>S</i>.Tm* or isogenic derivatives <i>S</i>.Tm^SipA, <i>S</i>.Tm^SopE, <i>S</i>.Tm^avir (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0013804#s2" target="_blank">Material and Methods</a>). We analyzed colonization levels in the gut lumen (A) and the mLN (B), as well as the degree of inflammation of the cecum mucosa (C). n.s.: No significant difference between <i>Il17ra^−/−</i> mice and <i>Il17ra^+/−</i> littermates. Strippled line: minimal detectable value.
