The effect of teicoplanin on leukocytic activity and intraleukocytic micro-organisms.
The interference of teicoplanin with certain phagocyte activities was investigated in comparison with that of vancomycin. Neither teicoplanin nor vancomycin interfered with chemotaxis, adherence, phagocytosis or nitroblue tetrazolium reduction of human neutrophils. Teicoplanin, but not vancomycin, enhanced intracellular killing by neutrophils from normal donors and from a patient with chronic granulomatous disease. Human monocytes in the absence of fresh human serum did not significantly kill Staphylococcus aureus but when pre-treated with teicoplanin 90% of phagocytozed bacteria were killed during 4 h incubation.
