目的:对临床分离产ESBLs肺炎克雷伯菌相关基因进行研究,并对其进行基因分型。方法:临床分离295株肺炎克雷伯菌,ESBLs药敏试验采用K-B法。PCR法检测I类整合酶、I类整合子基因盒、ISCR1、blaTEM、blaSHV、blaCTX-M。I类整合子PCR扩增阳性产物送去测序,测序结果在GenBank中用blastn进行核酸序列同源性搜索。菌株基因分型采用ERIC-PCR法。结果:产ESBLs肺炎克雷伯菌阳性率为21.3%。在63株产ESBLs肺炎克雷伯菌中,分为35个基因型,I类整合酶、ISCR1、blaTEM、blaSHV、blaCTX-M的阳性率分别为46.0%、12.7%、55.6%、0、81.0%,27个I类整合子含有7种类型基因盒。结论:在产ESBLs肺炎克雷伯菌中,I类整合子携带率较高,ESBLs基因型以blaTEM和blaCTX-M为主。我院产ESBLs肺炎克雷伯菌存在某种流行株。
目的:對臨床分離產ESBLs肺炎剋雷伯菌相關基因進行研究,併對其進行基因分型。方法:臨床分離295株肺炎剋雷伯菌,ESBLs藥敏試驗採用K-B法。PCR法檢測I類整閤酶、I類整閤子基因盒、ISCR1、blaTEM、blaSHV、blaCTX-M。I類整閤子PCR擴增暘性產物送去測序,測序結果在GenBank中用blastn進行覈痠序列同源性搜索。菌株基因分型採用ERIC-PCR法。結果:產ESBLs肺炎剋雷伯菌暘性率為21.3%。在63株產ESBLs肺炎剋雷伯菌中,分為35箇基因型,I類整閤酶、ISCR1、blaTEM、blaSHV、blaCTX-M的暘性率分彆為46.0%、12.7%、55.6%、0、81.0%,27箇I類整閤子含有7種類型基因盒。結論:在產ESBLs肺炎剋雷伯菌中,I類整閤子攜帶率較高,ESBLs基因型以blaTEM和blaCTX-M為主。我院產ESBLs肺炎剋雷伯菌存在某種流行株。

Objective:Of clinical separation ESBLs pneumonia klebsiella bacteria related genes, and genes.Methods:Clinical isolated 295 strains of pneumonia klebsiella bacteria, ESBLs drug sensitive test using the K - B method. PCR method to detect the I class integrase, class I integron gene box, ISCR1, blaTEM, blaSHV, blaCTX -m. Class I integron PCR amplification positive product sent to sequencing, the sequencing results in using blastn GenBank nucleic acid sequence homology search. Strain genotyping by ERIC - PCR method.Results: Producing ESBLs pneumonia klebsiella bacteria positive rate was 21.3%. In 63 strains producing ESBLs pneumonia klebsiella bacteria, divided into 35 genotypes, I class integrase, ISCR1, blaTEM, blaSHV, blaCTX - M positive rate were 46.0%, 12.7%, 55.6%, 0, 81.0%, 27 class I integron box containing the 7 types of gene.Conclusions:In producing ESBLs pneumonia klebsiella bacteria, class I integron carried rate is higher, ESBLs genotypes is given priority to with blaTEM and blaCTX - M. Our producing ESBLs pneumonia klebsiella bacteria exist some kind of epidemic strains.
