Zmp is not implicated in adhesion to PBEC under ALI conditions. Immunofluorescence analyses of PBEC differentiated under ALI conditions and infected for 4 h with A S. suis wild-type P1/7 (WT) and B S. suis ∆zmp strain. Ciliated cells were stained for ß-tubulin (red) and streptococci (green). Bars represents 50 µm. C Adherent bacteria were quantified by analyzing the epithelial cell surface positive for green fluorescence signal in four randomly chosen areas for each treatment. Results are expressed as mean ± SEM.
