[Phagocytosis of bacteria by polymorphonuclear leukocytes suspended in liquid or adhering to a surface].
Phagocytosis of Staphylococcus aureus by polymorphonuclear leukocytes (PNL) was studied in healthy men. PNL suspended in nutrient medium did not practically ingest bacteria. The intake of bacteria got considerably intensified if leukocytes and bacteria ran into each other by turning over the test tubes during incubation. A still greater rise of phagocytic activity was discovered under the conditions favouring the attachment of PNL to the surface and the possibility of chemotaxis. These conditions were created by introducing a gelatin-coated film into the test tube.
