Figure 2. Pulmonary immune cell numbers in rats with acute pneumonia.
Rats were nasally infected with 1 × 108Streptococcus pneumoniae colony forming units (CFU). Eight post-infection, lungs were collected and measured for the total number of pulmonary immune cells. Data are means ± SE. * Denotes P < 0.05 compared to control. ** Denotes P< 0.01 compared to control. N=10 rats per group.
