We have developed a method that enables the rates of phagocytosis and killing of bacteria by neutrophils to be measured in a single assay. Neutrophils were incubated with bacteria, and at specific intervals were separated from uningested bacteria by low speed centrifugation. Rates of phagocytosis and killing were calculated from the decrease in number of extracellular bacteria and change in the number of intracellular bacteria. Both phagocytosis and killing were shown to follow first‐order… Expand
Quantification of Phagocytosis in Human Neutrophils by Flow Cytometry
The authors' experiments proved that flow cytometric analysis is accurate and useful for characterizing phagocytosis, adherent bacteria can be distinguished from ingested bacteria after quenching with ethidium bromide, and that phagcytosis kinetics of two bacteria with different onsets of phagocytetosis can be determined by flow cytometry and the assessment of a score that quantifies phagocytes.

Methods for quantifying phagocytosis and bacterial killing by human neutrophils.
A detailed protocol is provided for a comprehensive microbiological technique that measures both phagocytosis and killing in a single assay, along with a kinetic analysis for measuring and calculating separate rate constants for the two events. Expand
Involvement of superoxide and myeloperoxidase in oxygen-dependent killing of Staphylococcus aureus by neutrophils
It is concluded that myeloperoxidase-dependent processes are strongly favored by human neutrophils as their prime mechanism of oxidative killing of S. aureus and that superoxide makes a direct contribution to killing. Expand
Modification of neutrophil oxidant production with diphenyleneiodonium and its effect on bacterial killing.
Correlation of hydrogen peroxide or hypochlorous acid production with the killing of S. aureus showed that up to 30% inhibition had no effect on the rate of killing, implying that agents that impair neutrophil oxidant production less than this will not compromise bacterial killing. Expand
Apoptosis of monocytes and prolonged survival of granulocytes as a result of phagocytosis of bacteria
It is suggested that granulocytes and monocytes react differently to phagocytosis of bacteria, as determined by light microscopy and DNA fragmentation detected by gel electrophoresis. Expand
Phagocytosis and killing of Staphylococcus aureus by bovine neutrophils after priming by tumor necrosis factor-alpha and the des-arginine derivative of C5a.
Bovine neutrophils have enhanced bactericidal activities at inflammatory sites when TNF-alpha, C5a(desArg), or both are produced locally. Expand
Bacterial killing by neutrophils in hypertonic environments.
It is concluded that physiologic levels of sodium chloride and urea will slow, but not prevent, neutrophil activity at a hypertonic site of infection. Expand
The interrelationship between phagocytosis, autophagy and formation of neutrophil extracellular traps following infection of human neutrophils by Streptococcus pneumoniae
Findings show a complex interaction between phagocytosis, killing, autophagy and NET formation in neutrophils following pneumococcal infection that contribute to host defence against this pathogen. Expand
Analysis of neutrophil bactericidal activity.
This chapter provides details of a comprehensive microbiological technique that quantifies neutrophil bactericidal activity by measuring the loss of viability of ingested bacteria over time. Expand
Analysis of Neutrophil Bactericidal Activity.
This chapter describes three methods for measuring the bactericidal activity of neutrophils and presents a method for selectively monitoring the long-term survival of bacteria within the phagosome. Expand


Kinetics of phagocytosis of Staphylococcus aureus and Escherichia coli by human granulocytes.
The present study showed that the rate of ingestion of Staphylococcus aureus and Escherichia coli depends on the concentrations of the granulocytes and bacteria, and the effect of temperature on the phagocytosis of micro-organisms proved to be two-fold. Expand
Kinetics and mechanism of the bactericidal action of human neutrophils against Escherichia coli.
This new assay measures phagocytosis and killing in a fast, simple, and accurate way; it is not hindered by extracellular bacteria and also measures the postkilling event of inactivation of a bacterial protein, which permits a better detection of neutrophils deficient in this function. Expand
A comparison between polymorphonuclear leucocytes obtained from normal and immune animals revealed no differences in their ability either to ingest or kill coagulase-positive staphylococci. Expand
Kinetics of intracellular killing of Staphylococcus aureus and Escherichia coli by human granulocytes
The intracellular killing of Staphylococcus aureus and Escherichia coli by human granulocytes was investigated independently of the ingestion of these bacteria. Granulocytes were allowed toExpand
Assay of the human leukocyte enzymes myeloperoxidase and eosinophil peroxidase.
Methods reported here may prove useful for measuring leukocyte influx into inflamed tissues, detecting MPO or EPO deficiencies, and measuring enzyme synthesis and secretion. Expand
Chlorination of taurine by human neutrophils. Evidence for hypochlorous acid generation.
It appears that stimulated human neutrophils can utilize the hydrogen peroxide-myeloperoxidase-chloride system to generate taurine chloramine, and the biologic reactivity and cytotoxic potential of hypochlorous acid and its chloramine derivatives suggest that these oxidants play an important role in the inflammatory response and host defense.

Defective Bactericidal Activity in Myeloperoxidase-deficient Human Neutrophils
