Abstract

The mechanism of resistance to some cephalosporins in Staphylococcus aureus strains was investigated with high-pressure liquid chromatography and nuclear magnetic resonance spectrometry. Drug inactivation by penicillinase was found to be the main mechanism of resistance to cefazolin, cephaloridine, and cephalothin in S. aureus.

摘要

采用高压液相色谱法和核磁共振光谱法,对金黄色葡萄球菌菌株对某些头孢菌素的耐药机制进行了研究。发现青霉素酶使药物失活是金黄色葡萄球菌对头孢唑林、头孢噻啶和头孢噻吩耐药的主要机制。
