Influence of various antibiotics on phagocytosis of Staphylococcus aureus by human polymorphonuclear leucocytes.
The influence of several new antibiotics on phagocytosis of two strains of Staphylococcus aureus by human polymorphonuclear leucocytes was studied with a radioisotopic method. The following antibiotics were tested in concentrations obtained in the serum after standard administration: gentamicin, netilmicin, amikacin, oxacillin, clindamycin, vancomycin, teicoplanin, rifampicin, ansamycin, coumermycin, enoxacin, ciprofloxacin, two new fluoro-quinolones CI 934 and RO 236240, and LY 146032 a new lipopeptidic antibiotic. Among them, only coumermycin significantly decreased phagocytosis, this was dependent on concentration, strain and source of the polymorphonuclear leucocytes.
