The number of ESBL-producing Enterobacteriaceae in community-acquired urinary tract infections worldwide is probably underestimated because of the technical difficulties encountered with their detection. In this study, out of 5,672 urine samples analyzed, 916 were positive for uropathogens, 472 of them being enterobacteria of which 7.6% produced β-lactamases. Analysis of the isolated from 36 patients showed a high level of antibiotic resistance, with 52.7% and 80.5% of isolates expressing bla TEM and bla CTX-M, respectively.
在全球范围内,由于检测技术上的困难,社区获得性尿路感染中产生 ESBL 的肠杆菌科的数量可能被低估了。在这项研究中,在分析的 5672 个尿样中,有 916 个为尿病原体阳性,其中 472 个为肠杆菌,其中 7.6%产生了β-内酰胺酶。对 36 名患者分离出的菌株进行分析显示出高度的抗生素耐药性,分别有 52.7%和 80.5%的分离株表达 blaTEM 和 blaCTX-M。
