Infection profile of <i>ΔpfkA</i> mutant in mouse.

<p>8-weeks old female BALB/c mice were nasally infected with the wild-type (black circle) or Δ<i>pfkA</i> (open circle) strains. Four animals per time point per group were used. Bacterial loads in lung (A) and spleen (B) were determined by CFU counts. Data are expressed in Log₁₀ CFU per organ as the mean ± SD of four mice per group.
