Uptake, Transport, and Delivery of Antimicrobial Agents by Human Polymorphonuclear Neutrophils

By Gerald L. Mandell and Elizabeth Coleman


Polymorphonuclear neutrophils (PMN) are attracted to sites of infection. They have the potential to deliver antimicrobial agents to these sites if the agents enter the cells and do not alter migration. Penicillin G did not enter cells and was not transported by PMN. We found that azithromycin, ciprofloxacin, levofloxacin, moxifloxacin, and telithromycin were concentrated in PMN and transported toward a chemoattractant. These antimicrobial agents were released from the PMN and inhibited the growth of bacteria on test plates
