Specific elimination of NK cells by <i>P. aeruginosa</i>.

Absolute numbers of immune cells in total splenocytes (×105). Comparative statistical analyses of immune cell population in spleen at 24 h post infection of PAK were shown in Table 1. The numbers of immune cells including NK cells (NK1.1+/CD3e−), NKT cells (NK1.1+/CD3e+), T cells (NK1.1−/CD3e+), Neutrophils (Ly6G and Ly6C+), Macrophage (CD11b+) and B cells (B220+/CD19+) were determined by calculating the absolute numbers of each cell type from the FACS profiles and total cell numbers in the tissues. Results are expressed as mean±SD of three individual experiments (n = 3, *p<0.05).
