Research Abstract

We observed the influence of the host cells, human alveolar epithelial cells, monocytes and macrophages, on the antimicrobial activities of several antibiotics and we found antimicrobial activities of carbapenems (Cps) were decreased in the supernatant of the cells cultured with fetal calf serum (FCS)-free RPMI 1640 medium. The farther studies revealed human cell culture supernatants to decline the antibacterial activities of Cps. We developed a useful screening test for the combination of piperacillin and aminoglycosides for multidrug-resistant Pseudomonas aeruginosa (MDRP) using the disk diffusion based method. We presented the usefulness of this method compared with the Etest based method and the checkerboard method.
