Abstract
Twelve isolates of Streptococcus pneumoniae with decreased susceptibility by oxacillin screen were susceptible by the FOX panel (Micro Media Systems, Cleveland, Ohio), a commercial microdilution system designed for fastidious organisms. These organisms were found to be moderately susceptible or resistant by broth macrodilution and agar dilution methods. This discrepancy indicates that the FOX panel is not reliable for susceptibility testing of S. pneumoniae.
摘要
通过苯唑西林筛选显示敏感性降低的12株肺炎链球菌分离株，对FOX药敏板（微媒体系统公司，俄亥俄州克利夫兰）敏感，该药敏板是一种为苛求菌设计的商业微量稀释系统。通过肉汤稀释法和琼脂稀释法发现这些菌株为中度敏感或耐药。这种差异表明FOX药敏板用于肺炎链球菌的药敏试验不可靠。
