Fig 5. Bacterial loads in the BAL fluid, lung lobes, trachea, thoracic lymph nodes and spleen of pigs infected with P. aeruginosa.

Pigs were inoculated with 70 mL of an 8 x 10⁶ cfu/mL suspension of P. aeruginosa PAK strain. Controls were obtained by inoculating 70 mL of 1X sterile PBS. Data were analysed by two-way ANOVA followed by Bonferroni’s post hoc test. Data are means ± S.E.M. * indicates p<0.05. ** indicates p<0.01. *** indicates p<0.001.
