Abstract:
:A new method for measuring the uptake of Staphylococcus aureus by human polymorphonuclear neutrophils (PMN) using flow cytometry (FCM) is described. Bacteria were labeled with fluorescein isothiocyanate (FITC) and incubated with PMN in a suspension assay. At the end of the assay, phagocytosis was arrested by the addition of cold paraformaldehyde. Thereafter, phagocytosis was quantitated by FCM, using crystal violet to distinguish adherent versus ingested bacteria. The method was validated in multiple samples by reference to our microscopic technique; correlations of phagocytic indices were in good agreement. The FCM method was also found to be reproducible and provided a mean to detect low phagocyte values. Another feature of the approach is that FCM readings can be delayed without any appreciable alterations in the results.
