Fig. 2: Bacteriocin-mediated turnover triggers host inflammation.

Images denote lung sections, 2 days following intranasal inoculation of mice with either PBS or Spn (WT, Δblp, and Δply). A H&E-stained lung sections. Scale: 100 µm. B Immunofluorescence images. Scale: 50 µm. White arrows denote phagocytosed and lysed Spn. These are also depicted at ×5 magnification in insets, and in comparison with intact WT diplococci.
