Airway inflammation following challenge with Haemophilus influenzae or Prevotella nanceiensis in mice. Flow cytometry of bronchoalveolar lavage (BAL) cells (a), absolute cell numbers in BAL (b), chemokine/cytokine levels in lung tissue homogenates (c), representative haematoxylin & eosin-stained lung tissue sections (d), and pathology scores (e) obtained from murine lungs 24 hr after airway challenge with vehicle (PBS), Haemophilus influenzae or Prevotella nanceiensis. Data represent two independent experiments (n = 8, mean + SEM). *P < 0·05; **P < 0·01; ***P < 0·001.
