We report an atypical enteropathogenic Escherichia coli O127a:K63 strain with resistance to quinolones and extended-spectrum cephalosporins isolated from a 2010 food poisoning outbreak involving 112 adults in China. Two resistance genes [bla(CTX-M-15), aac(6')-Ib-c] and five mutations (two in gyrA, two in parC, one in parE) coexisted in this enteropathogenic E. coli strain.
我们报告了一株来自中国 2010 年一起涉及 112 名成年人的食源性疾病暴发的非典型肠致病性大肠杆菌 O127a:K63 菌株,该菌株对喹诺酮类和头孢菌素类抗生素均具有耐药性。该肠致病性大肠杆菌菌株中同时存在两种耐药基因[bla(CTX-M-15),aac(6')-Ib-c]和五种突变(gyrA 中的两种、parC 中的两种、parE 中的一种)。
