Abstract

Twenty-three of 89 enterotoxigenic strains of Escherichia coli were resistant to one or more antimicrobial agents. Eleven strains transferred resistance directly and five transferred resistance after mobilization. In three cases a resistant recipient was enterotoxigenic. One of these strains contained a conjugative plasmid carrying genes for both drug resistance and enterotoxin production. In the two other strains genes for drug resistance and enterotoxin production were carried on separate co-transferable plasmids.

摘要

89株产肠毒素大肠杆菌中有23株对一种或多种抗菌药物耐药。11株直接传递耐药性,5株在被激活后传递耐药性。在3例中,耐药受体是产肠毒素的。其中一株含有携带耐药基因和产肠毒素基因的接合质粒。在另外两株中,耐药基因和产肠毒素基因分别位于可共同转移的不同质粒上。
