Figure 8B shows the colony-forming unit (CFU) of bacteria recovered from the lungs compared to the initial inoculum at 18 h post infection, with a geometric mean indicated for each group. The WT PAO1 was able to colonize the lungs of infected mice, and the number increased by approximately 570% over the course of the 18 h infection (Figure 8B). In contrast, the ΔgtrS and ΔgltB bacteria were, respectively, recovered in numbers approximately at 52% and 38% of initial inoculum dose from lungs (Figure 8B). In complemented strains, the colonization was completely restored to WT levels (Figure 8B). The gene discussed is SMOX; the disease is infection.
