Abstract

The Oxoid combination disk method for detecting extended-spectrum beta-lactamases (ESBLs) depends on comparing the inhibition zones of cefpodoxime (10-microg) and cefpodoxime-plus-clavulanate (10- plus 1-microg) disks. The presence of clavulanate enlarged the zones for all of 180 ESBL-producing klebsiellae by >/=5 mm, whereas zones for cefpodoxime-susceptible isolates and cefpodoxime-resistant isolates with AmpC and K1 beta-lactamases were enlarged by </=1 mm. Good discrimination was achieved with either the NCCLS or the British disk method.

摘要

用于检测超广谱β-内酰胺酶(ESBLs)的奥克托克斯组合纸片法,是通过比较头孢泊肟(10微克)和头孢泊肟加克拉维酸(10微克加1微克)纸片的抑菌圈来进行的。克拉维酸的存在使180株产ESBLs的克雷伯菌的抑菌圈均扩大了≥5毫米,而对头孢泊肟敏感的菌株以及产AmpC和K1β-内酰胺酶的头孢泊肟耐药菌株的抑菌圈扩大≤1毫米。无论是采用美国国家临床实验室标准委员会(NCCLS)的方法还是英国纸片法,都能实现良好的区分。
