OBJECTIVES: Recently, a CTX-M-15 extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli O25b-ST131 clone, belonging to the B2 phylogenetic grou... C Olivier,D Hiran,U Mathew,... - 《Journal of Antimicrobial Chemotherapy》 被引量: 662发表: 2009年 The CTX-M-15-producing Escheric...
Two CTX-M-type genes were sequenced and had amino acid sequences indistinguishable from previously sequenced CTX-M-15 beta-lactamases. The ISEcp1 element was located upstream of bla(CTX-M-15) in the same position as previously described. In addition, 23 of the isolates produced TEM beta-...
另外一些基因型流行范围较小,如 OXA、PER、GES、VEB 和 SFO 等基因型。不同地区流行的基因亚型也有差异,在欧洲国家 CTX-M-15 检出率最高,其次是 CTX-M-14,在非洲和澳大利亚地区,CTX-M-15 占大多数,在亚洲,CTX-M-14 和 SHV-12 流行较广。 产ESBLs 大肠...
Interestingly, pMLST K7:A-:B- plasmids have been previously described among CTX-M-15-producing K. pneumoniae ST983 strains isolated from hospitalized patients in Malaysia [16], Tanzania [17], and South Africa [18]. In summary, we report genomic data of K. pneumoniae ST392 harboring blaCT...
摘要: CTX-M-15是一种同时具备水解头孢噻肟和头孢他啶能力的超广谱β-内酰胺酶,目前在世界各地广泛,快速的传播,甚至在局部地区出现暴发流行.本文就CTX-M-15酶的分子特点,流行病学及CTX-M-15编码基因(blaCTX-M-15)及其基因环境等研究方面作一综述.关键词:...

Discovery of three highly resistant CTX-M-15 mutants To examine whether any single mutations of theblaCTX-M-15gene could lead to increased resistance against the β-lactam drugs mecillinam and meropenem or the β-lactam-inhibitor combination piperacillin–tazobactam, we generated a library ofblaCT...
