Histogram of haptoglobin, C-reactive protein, and annexin A1 ELISA results (means of three tests) for BALF from uninfected control (n = 13), infected untreated (n = 17), and infected treated (n = 16) rabbits. (A) Hp concentration is high in BALF from untreated rabbits and minimal in BALF from uninfected and treated animals. (B) CRP level is abundant in BALF from untreated rabbits, while in BALF from treated and uninfected animals it is almost undetectable. (C) Anx A1 is present in BALF from uninfected animals, decreased following IPA infection, and restored after therapy.
