A single Salmonella enterica serovar Typhimurium isolate with an UT2 phage type producing an extended-spectrum beta-lactamase (ESBL) was identified in Canada in 2000. The isolate harbored two plasmids, one containing a bla(TEM-1) gene and the other containing a bla(SHV-2a) gene. The ESBL gene was located on a 70-kb transferable plasmid which also carried tetracycline and trimethoprim resistance elements.
2000年在加拿大鉴定出一株具有UT2噬菌体类型、产生超广谱β-内酰胺酶(ESBL)的肠炎沙门氏菌鼠伤寒血清型菌株。该菌株携带两个质粒,一个含有bla(TEM-1)基因,另一个含有bla(SHV-2a)基因。ESBL基因位于一个70 kb的可转移质粒上,该质粒还携带四环素和甲氧苄啶抗性元件。
