The aac(6')-Ib gene was detected in 86 of 555 (15.5%) Enterobacteriaceae isolates. Among these 86 aac(6')-Ib-positive isolates, 19 (22.0%) were positive for aac(6')-Ib-cr: 4 of 31 (12.9%) Enterobacter spp., 7 of 13 (53.8%) Escherichia coli isolates, and 8 of 42 (19.0%) Klebsiella pneumoniae isolates. There was a strong association between aac(6')-Ib-cr and OXA-1 and CTX-M-1 group beta-lactamase genes. One aac(6')-Ib-positive K. pneumoniae isolate carried both aac(6')-Ib-cr and qnrS.
在555株肠杆菌科分离菌株中,检测到86株(15.5%)含有aac(6')-Ib基因。在这86株aac(6')-Ib阳性分离菌株中,19株(22.0%)aac(6')-Ib-cr呈阳性:在31株阴沟肠杆菌中有4株(12.9%),在13株大肠埃希菌中有7株(53.8%),在42株肺炎克雷伯菌中有8株(19.0%)。aac(6')-Ib-cr与OXA-1和CTX-M-1组β-内酰胺酶基因之间存在密切关联。1株aac(6')-Ib阳性肺炎克雷伯菌分离株同时携带aac(6')-Ib-cr和qnrS。
