EAEA

EAEA is one of the intelligence optimization algorithms. In EAEA, the estimation of distribution algorithm and elite reservation are embedded into AEA to generate a comparison population for iteration needs.

EAEA是一种智能优化算法，它将分布估计算法和精英保留策略加入到AEA中，用于产生候选参数的对比种群。

Methods: Seven genes of stx 1, stx 2, hly, eaeA , uidA , rfbE , fliC from different strains were detected by PCR and multiplex PCR.

方法: 利用单一PCR和多重聚合酶链反应(mPCR) 检测不同来源菌株志贺样毒素(stx1和stx2) 、 溶血素( hly )、粘附抹平因子(eaeA) 、 β-葡糖醛酸糖苷酶(uidA )、O157抗原编码(rfbE) 、 H7鞭毛抗原编码(fliC)基因.

Detection of the eaeA gene in Escherichia coli isolated from children with diarrhoea and characterization of the strains possessing the eaeA gene

腹泻儿童粪便分离的大肠杆菌中eaeA基因的检测及携带eaeA菌株的特性研究

Results The overall virulence gene prevalence was 62.7% ( 42/ 67); and the main virulence gene type was slt_1+ slt_2+ eaeA+ hly.

结果62.7%的株菌（42/67）携带有毒力基因，毒力图谱类型主要为slt1+slt2+eaeA+hly。

This indicates that eaeA gene is not limited to EPEC and EHEC, that the eaeA harbouring E. coli are heterogeneous with respect to their virulence determinants.

提示eaeA基因的分布不仅限于EPEC和EHEC，而且携带eaeA基因菌株含有多种毒力决定因子。

All eaeA positive isolates were rhamnose positive.

生化试验表明eaeA阳性 的大肠杆菌为乳糖发酵试验弱阳性的菌株.
