Ceftazidime-hydrolysing CTX-M-15 extended-spectrum beta-lactamase (ESBL) in Poland [PDF]

Journal of Antimicrobial Chemotherapy, 2002
The CTX-M-15 extended-spectrum beta-lactamase (ESBL) was recently identified in Enterobacteriaceae isolates in India, and demonstrated significant hydrolytic activity against ceftazidime, in contrast to the majority of CTX-M enzymes. CTX-M-15 differs from CTX-M-3, which is one of the most prevalent ESBLs in Poland, by only a single amino acid change ...

CTX-M-33, a CTX-M-15 derivative conferring reduced susceptibility to carbapenems. [PDF]

Antimicrob Agents Chemother, 2019
CTX-M-type extended-spectrum β-lactamases (ESBLs) are widespread among Enterobacterales strains worldwide. The most common variant is CTX-M-15, which hydrolyzes ceftazidime at a high rate but spares carbapenems. Here, we identified CTX-M-33, a point mutation derivative of CTX-M-15 (Asp to Ser substitution at Ambler ...

Veterinary Hospital Dissemination of CTX-M-15 Extended-Spectrum Beta-Lactamase-Producing Escherichia coli ST410 in the United Kingdom [PDF]

, 2016
We characterized extended-spectrum beta-lactamases (ESBLs) and plasmid-mediated quinolone resistance (PMQR) in 32 Escherichia coli extended spectrum cephalosporin (ESC)-resistant clinical isolates from UK companion animals from several clinics.

Complete Genome Sequence of Phage-Like Plasmid pECOH89, Encoding CTX-M-15 [PDF]

Genome Announcements, 2014
ABSTRACT A nonconjugative and nontypable plasmid of a clinical Escherichia coli isolate expressing resistance to extended-spectrum cephalosporins (ESCs) was isolated and sequenced. The plasmid pECOH89 contains a CTX-M-15 resistance cassette and comprises 111,741 bp, with strong homology to bacteriophage ...

The epidemic of extended-spectrum-beta-lactamase-producing Escherichia coli ST131 is driven by a single highly pathogenic subclone, H30-Rx [PDF]

, 2013
The Escherichia coli sequence type 131 (ST131) clone is notorious for extraintestinal infections, fluoroquinolone resistance, and extended-spectrum beta-lactamase (ESBL) production, attributable to a CTX-M-15-encoding mobile element.
