Differential cell counts from BALF. Transgenic (TG) and WT mice were challenged with A. suis and euthanized 16 h postinoculation. BALF was collected, cytocentrifuged, and stained with May-Grünwald Giemsa. Data represent the means ± SEMs from two independent experiments (transgenic mice, n = 9; WT mice, n = 10). *, P < 0.05.
