Pulmonary clearance of P. aeruginosa mucoid strains from lungs of infected mice by antisera to PMA and PMA-FLA. (A) Clearance of strain 2192 (≈6.65 × 107 CFU/mouse) 4 h after infection (anti-PMA-FLA versus anti-PMA, P < 0.05; anti-PMA-FLA versus NRS, P < 0.01; anti-PMA versus NRS, P > 0.05). (B) Clearance of strain FRD1 (≈3.175 × 107 CFU/mouse) 4 h after infection (anti-PMA-FLA versus anti-PMA, P < 0.05; anti-PMA-FLA versus NRS, P < 0.001; anti-PMA versus NRS, P > 0.05). (C) Clearance of strain 8050 (≈3.175 × 107 CFU/mouse) 4 h after infection (anti-PMA-FLA versus anti-PMA, P < 0.05; anti-PMA-FLA versus NRS, P < 0.01; anti-PMA versus NRS, P > 0.05). Values for P were determined by one-way analysis of variance (ANOVA) with Bartlett's test for equal variances and Tukey's multiple comparison test.
