Proinflammatory cytokine and chemokine levels in cell-free BAL fluids at 24 h postinfection. Each bar represents average values, and the error bars show the standard errors of the means (n = 8 mice per group). Mice infected with P. aeruginosa PAO1/pMJT1-aiiM produced lower levels of TNF-α, IL-1β, IL-6, and MIP-2 in cell-free BAL fluid than in mice infected with PAO1/pMJT1.
