Synergistic Effect of Doripenem and Cefotaxime to Inhibit CTX-M-15 Type β-Lactamases: Biophysical and Microbiological Views

Frontiers in Pharmacology, 2017
CTX-M-15 type β-lactamase has the ability to hydrolyse cefotaxime, a third generation cephalosporin. The infections caused by multidrug resistant strains, especially CTX-M-15 producing strains are being treated with carbapenem group of β-lactam ...

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.

Prevalence of CTX-M β lactamases among Gram negative bacteria in a tertiary care hospital in Bangladesh

IMC Journal of Medical Science, 2015
Extended spectrum beta lactamases (ESBLs) produced by Gram negative bacteria are mainly mediated by three important genes, namely TEM, SHV and CTX-M. In this study, we used a multiplex PCR to determine the prevalence of CTX-M and its subgroups CTX-M-3 ...

Mutational change of CTX‐M‐15 to CTX‐M‐127 resulting in mecillinam resistant Escherichia coli during pivmecillinam treatment of a patient

MicrobiologyOpen, 2019
Pivmecillinam (amdinocillin pivoxil) is the recommended first‐choice antibiotic used to treat urinary tract infections (UTIs) in Denmark. The frequency of mutation to mecillinam (MEC) resistance is described as high in vitro; however, treatment of UTI ...

CTX-M Extended-spectrum β-Lactamases, Washington State

Emerging Infectious Diseases, 2007
To the Editor: The CTX-M–type β-lactamases are non-TEM and non-SHV plasmid-mediated, class A, extended-spectrum β-lactamases (ESBLs). The CTX-M–type β-lactamases have recently emerged as the most common type of ESBLs, with a global distribution (1). In contrast, the CTX-M–type ESBLs are rarely reported in the United States and have not been identified ...
