The internalized bacteria were estimated by flow cytometry, by measuring the mean fluorescence intensity (MFI) of the cells. The phagocytosis was analysed by flow cytometry or confocal microscopy. Images were assembled and analysed with the Leica Confocal software LCS Lite 2.6 (Leica Microsystem). Images were acquired with a TCS SP2 AOBS confocal microscope (Leica Microsystem, […]
