CTX-M-1 and CTX-M-15-producing in dog faeces from public gardens [PDF]

Acta Veterinaria Scandinavica, 2015
Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli are increasingly reported in dogs. The objective of this study was to provide data on the prevalence of ESBL-producing E. coli in dog faecal deposits in public gardens.A total of 209 faecal deposits collected in nine public gardens in Copenhagen, Denmark were screened by selective ...

CTX-M-93, a CTX-M Variant Lacking Penicillin Hydrolytic Activity [PDF]

Antimicrobial Agents and Chemotherapy, 2011
ABSTRACT Extended-spectrum β-lactamases (ESBLs) of the CTX-M type are increasingly being reported worldwide, with more than 90 known variants. Clinical Escherichia coli isolate Bre-1 was isolated in 2009 and displayed an unusual ESBL phenotype, made of a synergy image between expanded cephalosporins and ...

CTX-M-1, CTX-M-3, and CTX-M-14 β-Lactamases from Enterobacteriaceae Isolated in France [PDF]

Antimicrobial Agents and Chemotherapy, 2002
ABSTRACT Six clinical CTX-M-producing isolates of the family Enterobacteriaceae were detected between 1999 and 2000 in different French hospitals. Two strains produced CTX-M-1 and CTX-M-3 and four strains produced CTX-M-14, a mutant Ala-231→Val of CTX-M-9.

First Description of Klebsiella pneumoniae Harboring CTX-M β-Lactamases (CTX-M-14 and CTX-M-3) in Taiwan [PDF]

Antimicrobial Agents and Chemotherapy, 2002
ABSTRACT Klebsiella pneumoniae isolates from Taiwan medical centers (50 strains; 1998 to 2000) with a CTX-M resistance phenotype (ceftazidime susceptible and ceftriaxone or cefotaxime nonsusceptible) were selected for initial isoelectric focusing analysis. β-Lactamases with pIs of 7.9 ( n = 22)

First Report of CTX-M-32 and CTX-M-101 in <i>Proteus mirabilis</i> from Zagreb, Croatia. [PDF]

Antibiotics (Basel)
Background/Objectives: Proteus mirabilis is a frequent causative agent of urinary tract and wound infections in community and hospital settings. It develops resistance to expanded-spectrum cephalosporins (ESC) due to the production of extended-spectrum β-lactamases (ESBLs) or plasmid-mediated AmpC β-lactamases (p-AmpC).

Characterization of CTX-M-14- and CTX-M-15-producing Escherichia coli of porcine origin [PDF]

Journal of Antimicrobial Chemotherapy, 2012
Sir, The emergence of extended-spectrum b-lactamase (ESBL)producing Escherichia coli among human patients is largely due to the spread of CTX-M, especially the clonal spread of sequence type (ST) 131 E. coli producing CTX-M-15. In recent years ESBLproducing E. coli have also been detected in food and animals and ST131 has been detected in E.
