Naip5⁺ C57BL/6 mice restricted the growth of L. pneumophila that encode flagellin. C57BL/6 and A/J mice were infected via the trachea with L. pneumophila Lp01 or its flaA-deficient mutant, and the lung bacterial burden was quantified 1, 2, and 3 d later. Mean CFUs ± SD (error bars) are shown, each calculated from five animals.
