Abstract

The Australian Group on Antimicrobial Resistance performs regular period-prevalence studies to monitor changes in antimicrobial resistance in selected enteric Gram-negative pathogens. The 2011 survey focussed on hospital-onset infections, examining isolates from all specimens presumed to be causing disease. In 2011, 1,827 Escherichia coli, 537 Klebsiella species and 269 Enterobacter species were tested using a commercial automated method (Vitek 2, BioMérieux) and results were analysed using Clinical and Laboratory Standards Institute breakpoints from January 2012. Of the key resistances, non-susceptibilty to the third-generation cephalosporin, ceftriaxone, was found in 9.6% of E. coli and 9.5%-12.1% of Klebsiella spp. Non-susceptibility rates to ciprofloxacin were 10.6% for E. coli, 0.0%-8.3% for Klebsiella spp. and 0.0%-5.0% in Enterobacter spp. Resistance rates to gentamicin were 8.6%, 2.9%-10.9%, and 0.0%-15.6% for the same 3 groups respectively. Eight strains, 5 Klebsiella spp. and 3 Enterobacter spp. were shown to harbour a carbapenemase (IMP-4).

摘要

澳大利亚抗菌药物耐药性研究小组定期开展时期患病率研究，以监测特定肠道革兰氏阴性病原体的抗菌药物耐药性变化。2011年的调查聚焦于医院感染，检查了所有疑似致病标本中的分离株。2011年，使用商业自动化方法（Vitek 2，生物梅里埃公司）对1827株大肠杆菌、537株克雷伯菌属和269株肠杆菌属进行了检测，并采用临床和实验室标准协会2012年1月起的标准对结果进行分析。在主要耐药情况中，第三代头孢菌素头孢曲松的非敏感性在9.6%的大肠杆菌和9.5%-12.1%的克雷伯菌属中被发现。大肠杆菌对环丙沙星的非敏感性率为10.6%，克雷伯菌属为0.0%-8.3%，肠杆菌属为0.0%-5.0%。上述三组对庆大霉素的耐药率分别为8.6%、2.9%-10.9%和0.0%-15.6%。有8株菌株（5株克雷伯菌属和3株肠杆菌属）被证明携带碳青霉烯酶（IMP-4）。
