Occurrence of CTX-M-3, CTX-M-15, CTX-M-14, and CTX-M-9 extended-spectrum beta-lactamases in Enterobacteriaceae clinical isolates in Korea.
Among 603 isolates of Enterobacteriaceae collected between June and November 2003 from three university hospitals within Korea, bla(CTX-M-3), bla(CTX-M-15), bla(CTX-M-14), and bla(CTX-M-9) were detected in 41 isolates of species from five different genera of Enterobacteriaceae, Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii, Enterobacter spp., and Serratia marcescens.
متن کاملDetection of CTX-M-1, CTX-M-15, and CTX-M-2 in clinical isolates of Enterobacteriaceae in Bogota, Colombia.
This is the first report regarding the detection of blaCTX-M genes encoding CTX-M-1, CTX-M-15, and CTX-M-2 cefotaximases in clinical isolates of enterobacteria collected in hospitals in Bogotá, Colombia. During a period of 4 months in 2005, 117 isolates of enterobacteria having extended spectrum beta-lactamase (ESBL) phenotype were collected from nine third-level hospitals in Bogotá, Colombia. ...
متن کاملCTX-M-137, a hybrid of CTX-M-14-like and CTX-M-15-like β-lactamases identified in an Escherichia coli clinical isolate.
OBJECTIVES To characterize a novel CTX-M chimera, CTX-M-137, from Escherichia coli clinical isolates in China. METHODS Isolates were collected from five hospitals between 22 February 2009 and 20 December 2011. Resistance genes were investigated by PCR. blaCTX-M-137 was cloned and purified for kinetic measurements. Conjugation experiments, S1-PFGE and Southern blotting were performed to study ...
متن کاملCTX-M-14 and CTX-M-15 enzymes are the dominant type of extended-spectrum β-lactamase in clinical isolates of Escherichia coli from Korea
This study was performed to assess the prevalence and genotypes of plasmid-borne extended-spectrum beta-lactamases (ESBLs) and AmpC beta-lactamases in Escherichia coli in Korea. A total of 576 isolates of E. coli was collected from 12 Korean hospitals during May and July 2007. A phenotypic confirmatory test detected ESBLs in 82 (14.2 %) of the 576 E. coli isolates. The most common types of ESBL...
متن کاملCTX-M-123, a novel hybrid of the CTX-M-1 and CTX-M-9 Group β-lactamases recovered from Escherichia coli isolates in China.
The chimeric bla(CTX-M-123) gene was identified in two ceftazidime-resistant Escherichia coli isolates from animals in different Chinese provinces. Like other CTX-M-1/9 group hybrids (CTX-M-64 and CTX-M-132), the ends (amino acids 1 to 135 and 234 to 291) of CTX-M-123 match CTX-M-15 while the central part (122 to 241) matches CTX-M-14. bla(CTX-M-123) is carried on related, but not identical, ~9...
