目前发现的的CTX-M型ESBLs种类超过107种,根据其氨基酸序列的差异(大于94%的相同序列认为是一个群,小于90%的相同序列认为是不同的群)分为5个群[3]:CTX-M-1 群包括 CTX-M-1、CTX-M-3、CTX-M-10、CTX-M-12、CTX-M-15、FEC-1、CTX-M-22、CTX-M-23、CTX-M-28、CTX-M-55 和 CTX-M-79;CTX-...

The 17 isolates were shown to have bla(CTX-M) genes that were associated with large plasmids (> or =58 kb), which also carried a tetracycline resistance gene, tet(A), and various aminoglycoside resistance genes. Two CTX-M-type genes were sequenced and had amino acid sequences ...
The emergence of ESBLs followed the introduction into clinical practice of expanded-spectrum cephalosporins, which are acknowledged to be the most powerful selectors for these resistance determinants. The spread of ESBLs represents a major challenge to the activity of these drugs, which were a milesto...
CONCLUSIONS: This work shows that CTX-M-12, which confers high-level resistance to cefotaxime but not to ceftazidime, has emerged in Korea. The bla(CTX-M-12) gene was associated with an upstream ISEcp1 insertion sequence. 展开 关键词: ISEcp1 horizontal transfer ERIC-PCR ...
Conclusion: The results of this study showed the blaCTX-M-15 gene in Enterobacteriaceae isolates for the first time in Mashhad, Iran. High degrees of associated resistance to co-trimoxazole and gentamicin were found in ESBL producers. Therefore, an integrated and regular management of antibiotic ...
1.METHODS The antimicrobial susceptibility test on ESBLs KPN which we have known its phenotype was conducted, then the CTX-M gene was amplified by polymerase chain reaction and detected.结果14株产ESBLs肺炎克雷伯菌药敏结果一致,耐三代头孢和耐酶抑制剂,均检出CTX-M基因。 2.Methods The CTX-M ge...
CTX-M-3 -carrying plasmids were identified among the enterobacteria studied. The presence of ISEcp1 in all isolates may be associated with the widespread resistance among Enterobacteriaceae. Although the plasmids were not identical, they appeared to belong to the same incompatibility group (IncI1-...
