Phagocytosis mediated by murine alveolar macrophages.

<p>(A) Adhesion of D39 wild-type strain and <i>lytB</i>, <i>lytC</i> and <i>lytB lytC</i> strains to alveolar macrophages. (B and C) Phagocytosis of the wild-type D39 and CWHs defective strains by alveolar macrophages. Error bars represent the SDs and asterisks indicate statistical significance compared to the wild-type strain (two-tailed Student's <i>t</i> test; *, <i>P</i><0.05; **, <i>P</i><0.01; ***, <i>P</i><0.001). <i>P</i><0.05 and <i>P</i><0.01 for the comparison of the results in adhesion and phagocytosis for <i>lytB lytC</i> vs. <i>lytB</i> or <i>lytC</i> respectively. <i>P</i><0.001 for the overall comparison in phagocytosis (one-way ANOVA with a post hoc Dunnett test).
