Abstract

Kirby-Bauer disk susceptibility tests with five standard cephalosporin disks were performed on 23 penicillin-resistant Streptococcus pneumoniae isolates for which ceftriaxone MICs were 0.125 to 4 micrograms/ml. Cefuroxime disk inhibition zone diameters distinguished clearly isolates for which ceftriaxone MICs were > or = 2 micrograms/ml from more susceptible strains, whereas cephalothin, ceftizoxime, cefotaxime, and ceftriaxone disks distinguished these isolates less clearly than the cefuroxime disk did.

摘要

对23株对青霉素耐药的肺炎链球菌分离株进行了Kirby-Bauer纸片药敏试验,这些分离株的头孢曲松MIC为0.125至4微克/毫升,使用了5种标准头孢菌素纸片。头孢呋辛纸片抑菌圈直径能清晰地区分头孢曲松MIC≥2微克/毫升的分离株与更敏感的菌株,而头孢噻吩、头孢唑肟、头孢噻肟和头孢曲松纸片区分这些分离株的效果不如头孢呋辛纸片明显。
