Abstract
We reported a case of Escherichia coli with colistin resistance and an extensively drug-resistant phenotype. Molecular analysis revealed that the isolate carried mcr-1 and multiple β-lactamase genes includingblaNDM1, blaCTX-M-15, blaTEM1, and blaCMY-2. This is the first report of a clinical mcr-1 isolate in Thailand highlighting the urgent need for a comprehensive antimicrobial resistance containment strategy to prevent further spread.
