這名來自康乃狄克州的兩歲女童，今年稍早被確診為大腸桿菌。CDC星期五證實她使用“最后的抗生素”粘菌素（colistin）無效，成為美國第四位抗粘菌素的人。去年，中國、歐洲與加拿大相繼在牲畜和人體內(nèi)發(fā)現(xiàn)了帶有MCR－1基因、可對抗多粘菌素的超級細菌。
部分原文報道如下：
Health officials have detected a potentially deadly superbug in a fourth US patient, the Centers for Disease Control and Prevention announced today. In July, scientists identified a strain of Escherichia coli that the antibiotic of last resort cannot treat in a Connecticut pediatric patient.
The girl had traveled to the Caribbean and developed fever and bloody diarrhea on June 12, two days before returning to the US. During the illness, the child made outpatient visits to a clinic and once to an emergency room, but did not require hospitalization.
