Abstract

Fifty-seven cultures of Haemophilus influenzae were tested for production of beta-lactamase by use of a modified, 1-min test. Only the 24 cultures that were ampicillin resistant, whether type b or not, yielded positive results for the enzyme; all ampicillin-susceptible isolates were uniformly negative. The beta-lactamase procedure is simple to perform and requires only commonly available reagents.

摘要

采用改良的1分钟检测方法,对57株流感嗜血杆菌培养物进行了β-内酰胺酶检测。只有24株对氨苄西林耐药的培养物(无论是否为b型)酶检测呈阳性;所有对氨苄西林敏感的分离株均呈阴性。β-内酰胺酶检测方法操作简单,仅需常用试剂。
