Colistin resistance genes mcr-3 and mcr-1 have been detected in an Escherichia coli isolate from cattle faeces in a Spanish slaughterhouse in 2015. The sequences of both genes hybridised to same plasmid band of ca 250 kb, although colistin resistance was non-mobilisable. The isolate was producing extended-spectrum beta-lactamases and belonged to serotype O9:H10 and sequence type ST533. Here we report an mcr-3 gene detected in Europe following earlier reports from Asia and the United States.
2015年，在西班牙一家屠宰场的一份牛粪便大肠杆菌分离株中检测到了耐黏菌素基因mcr - 3和mcr - 1。尽管黏菌素耐药性不可转移，但这两个基因的序列均与约250 kb的同一质粒条带杂交。该分离株产生超广谱β-内酰胺酶，属于O9:H10血清型和ST533序列型。继亚洲和美国早期报告之后，我们在此报告了在欧洲检测到的一个mcr - 3基因。
