确证试验 meaning in English

confirmatory test

Part 1 study on the antibiotic resistance of escherichia coil and klebsieua pneumoniae producing extended - spectrum beta - lactamases objective to investigate the prevalence of strains producing esbls among escherichia coil and klebsieua pneumoniae , look for the best detection substrate of these strains and determine the antibiotic resistance of them . methods 248 strains of e . coli . and 97 strains of k . pn from january to october , 2002 were investigated for production of extended - spectrum b - lactamases ( esbls ) by phenotypic screening and confirmatory test provided by the national committee for clinical laboratory standards ; compared the result of the phenotypic screening and confirmatory test to discuss the best detection substrate of these strains ; 16 kind of antibiotics were selected for antimicrobial susceptibility test for the resistance
方法对2002年1 ? 10月临床分离的248株e . coli和97株k . pn ，采用美国临床实验室标准委员会( nccls )规定的esbls表型筛选和确证试验，确定本地区esbls的发生率；通过对不同底物的初筛结果与确证试验结果的比较，探讨本地区临床检测产esbls菌株的最佳筛选底物；选择16种抗生素纸片做药敏试验，了解产esbls的e . coli和k . pn的耐药性。
