Bacterial burdens in BALB/c mice’s blood, liver, and lung tissues. The procedure of vaccination and A. baumannii challenge. BALB/c mice were infected with fatal concentrations of A. baumannii ATCC19606 (2108 CFU/mouse) 3 weeks after their last vaccination. A Bacterial burdens in mice’s blood 24 h after the challenge. Bacterial burdens in the liver and lungs B–C. After a 24-h challenge with A. baumannii, the liver and lungs were removed. The mean SD (n = 6) is indicated by the bars. (ns nonsignificant, *p ≤ 0.05; **p ≤ 0.01, ***p ≤ 0.001, ****p ≤ 0.0001)
