Zusammenfassung: | In vitro activity of antimicrobial agents such as ABPC, SBPC, MPC, CEZ, CTM, CMZ, CTX, CMX, CZX, LMOX, CPZ, CFS and GM against major clinical isolates, S. aureus, S. pyogenes, E. coli, K. pneumoniae, P. mirabilis, C. freundii, Enterobacter spp., S. marcescens, P. vulgaris and P. aeruginosa, was examined. In this paper, we will report the susceptibility of S. aureus, S. pyogenes, E. coli, K. pneumoniae and P. mirabilis during a three-year period, 1981-4983. 1. CEZ-and GM-resistant S. aureus has markedly increased and occupied 24% and 18%, respectively, in 1983. CMZ and CFS have showed potent activity against CEZ-resistant S. aureus. It seems that the abuse of third generation-cephems and new oral cephalosporins is closely related with the increase of cephemsresistant S. aureus. 2. The penicillin-and cephem-resistant strains of S. pyogenes could not be found in our study. 3. Quite a few strains of E. coil, K. pneumoniae and P. mirabilis are resistant to penicillins, and also there is no appreciable change in susceptibility. Some strains of E. coli, K. pneumoniae and P. mirabilis showed low susceptibility to CPZ, but all strains showed high susceptibility and no change in susceptibility to third generations, and these strains showed no tendency to decrease in susceptibility to GM. |
