virulence genes (aggR, astA, pic, aaiA, aatA, and aaiG) of EAEC and HEp-2 cell adhesion test – the gold standard assay of EAEC were performed on the isolated E. coli strains. The EAEC positivity is determined according to following five

菌株主要携带的毒力基因为astA(42 株)、estIb(25 株)、pic(15 株)、escV(14 株)、aggR(14 株);最常见的毒力基因组合为astA + estIb(25 株)。 进一步分析发现，携带astA、estIb 基因的O148 和

High-precision 8/16/24 MHz factory-trimmed internal RC oscillator. In-application trimming access for frequency adjustment. Up to 48 I/O lines with external interrupt capability (edge or level), debouncing, glitch filtering and on-die series resistor termination.

其中利用eae、stx1、stx2、lt、st、aggR和ipaH 7种毒力基因进行DEC的分型鉴定，此外，检测并分析bfpA、astA、escV、pic、perA、ehxA、pet和ipaBCD等重要的毒力基因分布情况。

pic、aggR中至少有1个为阳性。所有菌株种属基因uidA 都应为阳性。astA、pic基因可在细菌间转移，当与其他毒 力基因同时阳性时不作为型别判断依据。 1.3.3 药敏试验 采用MIC和美国临床和实验室标 准协会（Clinical and Laboratory Standards Institute， CLSI）[3]的评价标准。

The detection of six virulence genes (aggR, astA, pic, aaiA, aatA, and aaiG) of EAEC and HEp-2 cell adhesion test – the gold standard assay of EAEC were performed on the isolated E. coli strains.

目的 对肠集聚性大肠埃希菌(EAEC)分子诊断方法进行性能评价.方法 对2015年1月—2019年12月上海市浦东新区腹泻门诊病例粪便样本分别进行大肠埃希菌分离鉴定,并对分离株进行"金标准"HEp-2细胞粘附试验和6种毒力基因检测(aggR、astA、pic、aaiA、aatA、aaiG).根据不同基因 ...
