Figure 3.

Monocyte/macrophage subpopulations within the lung tissue. Total counts were calculated of CD14+/− CD163+/− CD203α+/− or MHCII+/− monocytes/macrophages (dark bar: CD+, clear bar: CD−) in alveolar and interstitial compartments, including the lesion (LL) compartment, before and 24 and 72 h after Actinobacillus pleuropneumoniae (APP) infection. The total counts of cells ± SEM per gram of lung tissue are shown. The significant differences (p < 0.05) between noninfected (0 h after infection) and infected piglets are marked with asterisks (*). IS, interstitial.
