Bacterial loads in lung and pro-inflammatory cytokine levels after intranasal challenge with <i>S</i>. <i>maltophilia</i>.

A. Mice were challenged intranasally with S. maltophilia 10 days after the last immunization. Twenty four hours after the challenge, S. maltophilia loads in lung homogenate were detected. Data are shown as the median with interquartile range. Results are representative for at least three independent experiments. ** P B) and IL-6 (C) in BALF were measured from rOmpA group and control group at 6h and 24h post-challenge. Data are shown as the mean ± SD. Results are representative for three independent experiments. * P <0.05 for the rOmpA group compared with control group (PBS) was analyzed by Mann-Whitney rank test (two-tailed).
