CXM treatment at 50 μg/mL could not clear the infection (intracellular or extracellular), and exponential increases in bacterial CFU were observed (Figure 4F), and the numbers of intracellular PAO1 enumerated at 3 h (∼103 – ∼105 CFU) in the presence of 200 μg/mL of CXM remained essentially unchanged by 24 h (Figure 4F). This evidence concerns the gene SMOX and infection.
