Abstract

A practical approach to detect and identify ceftazidime-hydrolyzing extended-spectrum mutants of OXA-10 beta-lactamase is presented. Large numbers of bacteria were screened by colony hybridization, a 720-bp part of blaOXA was amplified by PCR from the hybridization-positive isolates, and the products were digested by PvuII and HaeIII.

摘要

本文介绍了一种检测和鉴定水解头孢他啶的OXA-10超广谱β-内酰胺酶突变体的实用方法。通过菌落杂交筛选大量细菌,从杂交阳性分离株中通过PCR扩增blaOXA的720bp片段,并将产物用PvuII和HaeIII进行酶切。
