Lung histopathology in B. pseudohinzii-infected mice. (a–d) H&E-stained paraffin section; (c) and (b) represent higher magnifications of boxed areas in (b) and (a), respectively, demonstrating BALT aggregates; additional BALT is indicated by arrows in (a). The lung section depicted in a–c is taken from an animal which was also positive for Pasteurella pneumotropica. (d) Interstitial pneumonia with neutrophils (arrow). (e) The incidence of neutrophils is significantly elevated in the BAL fluid from B. pseudohinzii-positive (pos; n = 6) compared to B. pseudohinzii-negative mice (neg; n = 6) (mean ± SEM; Student’s unpaired t-test).
